The steps used in the solution of the equation -6 = -2/3(x + 12) + 1/3x are based on the principles of the Distributive Property, combining like terms, addition property of equality, symmetric property, subtraction property of equality, and multiplication property of equality.

Let's analyze the steps of the solution for the given equation -6 = -2/3(x + 12) + 1/3x:

Step 1: Distributive Property

The equation begins with the Distributive Property, which states that you can distribute a factor to each term inside parentheses. In this case, we distribute -2/3 to (x + 12), resulting in -2/3 * x and -2/3 * 12.

Step 2: Simplification

We simplify the expression -2/3 * 12 to -8, as multiplying -2/3 by 12 gives us -24, and simplifying the fraction -24/3 yields -8.

Step 3: Combine Like Terms

We combine the like terms -2/3x and -8. The equation becomes -2/3x - 8 + 1/3x.

Step 4: Combine Like Terms

We combine the like terms -2/3x and 1/3x by adding their coefficients. The sum of -2/3x and 1/3x is -1/3x.

Step 5: Addition Property of Equality

We add -1/3x to both sides of the equation to isolate the constant term. The equation becomes -6 - 1/3x = -1/3x.

Step 6: Symmetric Property

Since the equation has a form of -1/3x = -6 - 1/3x, we can rearrange the terms using the Symmetric Property.

Step 7: Addition Property of Equality

We add 1/3x to both sides of the equation to isolate the constant term. The equation becomes -6 = 0.

Step 8: Subtraction Property of Equality

We subtract 0 from both sides of the equation to simplify it further. The equation remains -6 = 0.

Step 9: Multiplication Property of Equality

We multiply both sides of the equation by any non-zero number to check for consistency. In this case, there is no need for multiplication as the equation is already in its simplified form.

Answer:

Step-by-step explanation:

The area of the obtuse triangle is 34 square feet with a base of 10 ft and height of 6.8 ft.

To find the area of the obtuse triangle, we can use the formula A = (1/2) * base * height. Let's denote the unknown part of the base as x.

In the given triangle, we have the width of the obtuse angle triangle as 10 ft, the height (perpendicular) as 6.8 ft, and the unknown part of the base as x.

Using the formula, we can calculate the area as:

A = (1/2) * (10 + x) * 6.8

Simplifying this expression, we get:

A = 3.4(10 + x)

Now, we need to determine the value of x. From the given information, we know that the width of the obtuse angle triangle is 10 ft. This means the sum of the two parts of the base is 10 ft. Therefore, we can write the equation:

x + 10 = 10

Solving for x, we find:

x = 0

Since x = 0, it means that one part of the base has a length of 0 ft. Therefore, the entire base is formed by the width of the obtuse angle triangle, which is 10 ft.

Now, substituting this value of x back into the area formula, we have:

A = 3.4(10 + 0)

A = 3.4 * 10

A = 34 square feet

Hence, the area of the obtuse triangle is 34 square feet.

Answer: -24

Step-by-step explanation:

To evaluate the expression, I guess we need to break it down into steps:

Expression: -3[-4(3-10)-12] / -2(-1)

Step1: Simplify the innermost parentheses Inside the square brackets: 3 - 10 = -7 Expression becomes: -3[-4(-7) - 12] / -2(-1)

Step2: Simplify the multiplication in square brackets: -4 * (-7) = 28. Expression becomes: -3[28 - 12] / -2(-1)

Step3: Simplify the subtraction inside the square brackets: 28 - 12 = 16. Expression becomes: -3[16] / -2(-1)

Step4: Simplify the multiplication outside the square brackets: -3 * 16 = -48. Expression becomes: -48 / -2(-1)

Step5: Simplify the multiplication inside the denominator: -2 * (-1) = 2 Expression becomes: -48 / 2

Step 6: Perform the division -48 divided by 2 is equal to -24

Answer: D: The cost of one hand towel is $8 and the cost of one bath towel is $5.

Step-by-step explanation:

Let's assume the cost of one hand towel is 'x' dollars and the cost of one bath towel is 'y' dollars.

For the first hotel, Mr. Miller ordered 27 hand towels and 48 bath towels, resulting in a bill of $540. This can be expressed as the equation:

27x + 48y = 540 ...(equation 1)

For the second hotel, Mr. Miller ordered 50 hand towels and 24 bath towels, resulting in a bill of $416. This can be expressed as the equation:

50x + 24y = 416 ...(equation 2)

To solve this system of equations, we can use any suitable method such as substitution or elimination. Let's use the elimination method:

Multiplying equation 1 by 2 and equation 2 by 3, we get:

54x + 96y = 1080 ...(equation 3)

150x + 72y = 1248 ...(equation 4)

Now, subtracting equation 4 from equation 3, we have:

(54x + 96y) - (150x + 72y) = 1080 - 1248

-96x + 24y = -168

Dividing both sides of the equation by -24, we get:

4x - y = 7 ...(equation 5)

Now, we have a system of equations:

4x - y = 7 ...(equation 5)

50x + 24y = 416 ...(equation 2)

Solving this system of equations, we find that x = 8 and y = 5.

Therefore, the cost of one hand towel is $8 and the cost of one bath towel is $5.

So, the correct answer is option D: The cost of one hand towel is $8 and the cost of one bath towel is $5.

Answer:

Step-by-step explanation:

Total cost of hand towels for first hotel = 27 * $5 = $135

Total cost of bath towels for first hotel = 48 * $8 = $384

Total cost of hand towels for second hotel = 50 * $5 = $250

Total cost of bath towels for second hotel = 24 * $8 = $192

Total cost of all hand towels = $135 + $250 = $385

Total cost of all bath towels = $384 + $192 = $576

Total number of hand towels = 27 + 50 = 77

Total number of bath towels = 48 + 24 = 72

Average cost of one hand towel = $385 / 77 = $5

Average cost of one bath towel = $576 / 72 = $8

Answer:

47 cents or $0.47

Step-by-step explanation:

1 dime = 10 cents (or $0.1)

1 quarter = 25 cents or ($0.25)

12 cents + 1 dime + 1 quarter = 12 + 10 + 25 = 47 cents

Part I- a) y = (x + 25)(x + 9)

b) y = x^2 + 34x + 225

c) y=  (x + 17)^2 - 64

d) The y-intercept is (0, 225), The y-intercept is (0, 225).

e) The graph of the parabola has the vertex at (-17, -64), x-intercepts at (-25, 0) and (-9, 0), and the y-intercept at (0, 225).

f) Only positive values of x make sense because the dimensions of a pool and deck cannot be negative.

g) y = 465 square yards

Part II- a) y = (6 + 2x)^2

b) 169 = (6 + 2x)^2

c) x = 3.5 feet

Part I:

y = (x + 25)(x + 9)

b) To rewrite the equation in standard form using the FOIL method:

y = x^2 + 9x + 25x + 225

= x^2 + 34x + 225

c) To rewrite the equation in vertex form by completing the square:

y = (x^2 + 34x) + 225

= (x^2 + 34x + (34/2)^2) + 225 - (34/2)^2

= (x^2 + 34x + 289) + 225 - 289

= (x + 17)^2 - 64

d) The vertex of the parabola is (-17, -64). The x-intercepts are found by setting y = 0 and solving the equation:

0 = (x + 17)^2 - 64

64 = (x + 17)^2

x + 17 = ±√64

x + 17 = ±8

x = -17 ± 8

x = -25, -9

Therefore, the x-intercepts are (-25, 0) and (-9, 0).

The y-intercept is obtained by setting x = 0 in the equation:

y = (0 + 17)^2 - 64

y = 17^2 - 64

y = 289 - 64

y = 225

Therefore, the y-intercept is (0, 225).

e) The graph of the parabola has the vertex at (-17, -64), x-intercepts at (-25, 0) and (-9, 0), and the y-intercept at (0, 225).

f) Only positive values of x make sense because the dimensions of a pool and deck cannot be negative. In this context, negative values for x would not provide meaningful solutions for the width of the deck.

g) The point on the graph that represents the total area including the pool but not the pool deck is the y-intercept (0, 225).

h) When x = 6 yards, the total area of the pool and deck can be found by substituting the value into the equation from Part b:

y = (6 + 17)^2 - 64

y = 23^2 - 64

y = 529 - 64

y = 465 square yards

Part II:

a) The equation for the area of the enclosed space in the form y = (side length)^2, considering the hot tub and the deck around it, is:

y = (6 + 2x)^2

b) Substituting the area of the enclosed space (169 square feet) for y in the equation:

169 = (6 + 2x)^2

c) Solving the equation for x:

√169 = √((6 + 2x)^2)

13 = 6 + 2x

2x = 13 - 6

2x = 7

x = 7/2

x = 3.5 feet

Therefore, the width of the deck space around the hot tub is 3.5 feet.

The equivalent function that best shows the x-intercepts on the graph of f(x) = 4x² - 1 is option (a) or (b): Of(x) = (4x + 1)(4x - 1).

The correct answer to the given question is option a or b.

The given function is f(x) = 4x² - 1. We need to choose the equivalent function that best shows the x-intercepts on the graph.The x-intercepts are the points where the graph of a function intersects the x-axis. At the x-intercepts, the value of y is zero.

Therefore, to find the x-intercepts, we need to solve the equation f(x) = 0 for x. The function f(x) = 4x² - 1 can be factored as:(2x + 1)(2x - 1)

To find the x-intercepts, we set f(x) = 0:4x² - 1 = 0(2x + 1)(2x - 1) = 0So, either 2x + 1 = 0 or 2x - 1 = 0. Solving these equations, we get:

x = -1/2 or x = 1/2

These are the x-intercepts of the graph of f(x) = 4x² - 1.Now, let's look at the given options and determine which one shows the x-intercepts on the graph:

Option (a):

Of(x) = (4x + 1)(4x - 1)

This is the factored form of f(x) = 4x² - 1. It correctly shows the x-intercepts.

Option (b):

Of(x) = (2x + 1)(2x - 1)

This is the same as option (a) and correctly shows the x-intercepts.

Option (c): f(x) = 4(x² + 1)

This function does not have any x-intercepts. It has a minimum value of 4 at x = 0.

Option (d): f(x) = 2(x² - 1)

This function has x-intercepts at x = -1 and x = 1. It does not show the x-intercepts of the given function.

Therefore, the equivalent function that best shows the x-intercepts on the graph of f(x) = 4x² - 1 is option (a) or (b):

Of(x) = (4x + 1)(4x - 1).

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 16 and h = 8 , then

A = [tex]\frac{1}{2}[/tex] × 16 × 8 = 8 × 8 = 64 ft²

The probability that the dial stops on yellow is 2/5 or 0.4 (or 40%).

Therefore, there is a 40% chance that the spinner will stop on yellow.

To find the probability that the spinner stops on yellow, we need to determine the number of favorable outcomes (yellow) and the total number of possible outcomes.

The spinner has 10 equally sized slices, with 4 yellow, 4 red, and 2 blue.

The number of favorable outcomes (yellow) is 4 because there are 4 yellow slices.

The total number of possible outcomes is 10 because there are 10 slices in total.

Therefore, the probability of the spinner stopping on yellow can be calculated as:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 4 / 10

Simplifying this fraction, we get:

Probability = 2 / 5

So, the probability that the dial stops on yellow is 2/5 or 0.4 (or 40%).

Therefore, there is a 40% chance that the spinner will stop on yellow.

Answer:

(x + 5)² + (y – 1)² = 25

Step-by-step explanation:

Note that the general equation of a circle is (x – h)² + (y – k)² = r², where (h, k) represents the location of the circle's center, and r represents the length of its radius.

The circle is 10 units in diamater, so the radius is half this: r=10/2=5.

The circle goes from -10 to 0 along the x-axis, so the x-coordinate of its centre is halfway between this: h=(-10+0)/2=-10/2=-5

The circle goes from -4 to 6 along the y-axis, so the y-coordinate of its centre is halfway between this: k=(-4+6)/2=-2/2=1

Now that we know r, h, and k, we can sub these into the general formula to get our equation:

(x - (-5))² + (y – 1)² = 5²

(x + 5)² + (y – 1)² = 25
