Answer:

y=5x+3

Step-by-step explanation:

Hi there!

We are given that a line has a slope of 5, and a y intercept of (0,3)

We want to write the equation of this line in slope-intercept form

Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept

Since we were given the slope and the y intercept, we can simply substitute these values into the formula to find the equation.

Starting with the slope:

Substitute 5 as m into the equation

y=5x+b

Now for the y intercept:
As stated before, b is the value of y at the y intercept; in this case, b is equal to 3

Substitute 3 as b into the equation.

y=5x+3

Hope this helps!

Answer:

67.5 square units

Step-by-step explanation:

Formulae

[tex]\textsf{Area of a triangle}=\sf \dfrac12bh[/tex]

(where b is the base and h is the height)

[tex]\textsf{Area of a trapezoid}= \sf \dfrac12(a+b)h[/tex]

(where a and b are the bases, and h is the height)

Solution

We can divide this shape into a triangle and a trapezoid.

[tex]\implies \textsf{Area of triangle}=\sf \dfrac12 \cdot 10 \cdot 7=35\:\textsf{(square units)}[/tex]

[tex]\implies \textsf{Area of trapezoid}= \sf \dfrac12(3+10)\cdot 5=32.5\:\textsf{(square units)}[/tex]

Therefore:

Area of shape = 35 + 32.5 = 67.5 square units

Answer:

     x(x +3) = 108

Step-by-step explanation:

The longer string is 3 inches longer than the shorter string, whose length is x. Then the longer string is (x+3), and the product of their lengths is ...

  x(x +3) = 108 . . . . . equation for finding the shorter length

__

In standard form, the equation is ...

  x² +3x -108 = 0

  (x -9)(x +12) = 0 . . . . . factored form

The values of x that make these factors zero are 9 and -12. The shorter string length is 9 inches.

_____

Additional comments

John's guitar is unusually small if its strings are 12 inches or less.

Note that factoring is accomplished by finding factors of 108 that differ by 3. This requires the same thinking process as solving the problem directly without the use of an equation. We know the product of two numbers is 108 and one is 3 larger than the other.

The difference (3) is sufficiently smaller than the product that the square root of the product (10.4) will be about halfway between the numbers. We can reasonably guess their values to be 10.5±3/2 = {9, 12}. (There is a more formal way to make this calculation by defining a variable (a) to be the average of the two lengths: Then you have (a-3/2)(a+3/2)=108, or a² = 110.25 and a=10.5. This matches our approximation.)

There are two ways to do this depending on the information you know.

Step-by-step explanation:

In order for a quadrilateral to be a rhombus, the sides have to be of equal length, so proving that all four sides are the same length would be one way. A second way is to prove that diagonals connecting opposite corners are perpendicular bisectors (connect in such a way that they cut each other into equal pieces at right angles).

Step-by-step explanation:

[1]    2x + y = -1

  [2]    x - 2y = -8  <------- given linear equations

Graphic Representation of the Equations : ----> given in attatchment

y + 2x = -1        -2y + x = -8  < ----- point where they connect is shown in graph

Solve by Substitution :

// Solve equation [2] for the variable  x

Step-by-step explanation:

We can apply the Pythagorean theorem to this problem. First, we need to square both legs. 7^2 = 49, and 25^2 = 625. If we add them, they equal 674. We then just take the square root of 674 which is 26.96. When rounded, that is 26.0

A straight angle is an angle equal to 180 degrees

Solve for y

y + 51° + 56° = 180°

y = 180° - 56° - 51°

y = 73°

Total interior angle of a triangle sum ups to 180°

Solve for x

y + x + 72° = 180°

73° + x+ 72° = 180°

x = 180° - 72° - 73°

x = 35°

You first convert 1/3 to 3, and division to multiplication. The equation is now  21 x 3, which is equal to 63.

If the campaign of Snyder’s Moving company costs $500 to execute, it has been computed that the profit will be C. $50,480.

Firstly, the customer base will be:

= 50% × [2200 - (10% × 2200)]

= 50% × (2200 - 220)

= 990

The increase in customers will be:

= 10% × 990

= 99

The additional profit will be:

= [(99 × $260) - $500] × 2

= ($25740 - $500) × 2

= $50480

Answer:

981.496    ft^3

Step-by-step explanation:

Volume of triangular pyramid is

 1/3  base area * height

area of a equilateral triangle base  is

 sqrt (3)/4  s^2     where s = side length

so the volume is

1/3  ( sqrt(3) / 4 ) (20^2)    *   17      ft^3

= 981.496  ft^3

Answer:

Area of a triangle is 1/2 x base x height.

area of triangle = 1/2 x 20 x 17 = 170 square feet.

the image shows 4 triangles, total area = 170 x 4 = 680 square feet.

the answer is A. 680 sq. ft.

Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval is (29.6, 44.4).

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 25 - 1 = 24 df, is t = 2.0639.

The other parameters are given by:

[tex]\overline{x} = 37, s = 18, n = 25[/tex].

Hence, the bounds of the interval are given as follows:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 37 - 2.0639\frac{18}{5} = 29.6[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 37 + 2.0639\frac{18}{5} = 44.4[/tex]

The 95% confidence interval is (29.6, 44.4).
