Answer:

y=-4x+0

Step-by-step explanation:

Slope form is y=mx+b

m is the slope, and b is the y intercept. If the line must pass through (0,0) then the y intercept would be zero.

This give you y=mx+0

Now to find the slope you need a perpendicular line to the previous line. This would mean you have to swap 1/4 which is the previous lines slope.

1/4 is a positive so make it a negative, -1/4

Now flip -1/4 to make is -4/1 which also equals -4

Now with the slope -4 and y-intercept 0, you know you equation

y=-4x+0

The solution to the expression is  7r - 8

The expression is given as

Answer:

[tex]\frac{5}{42}[/tex]

Step-by-step explanation:

It makes a difference if the marbles are place bag into the bag after selecting.  Since this is not stated, I am assuming that once a marble is selected, it is not placed back in the bag.

[tex]\frac{5}{9}[/tex] x [tex]\frac{4}{8}[/tex] x [tex]\frac{3}{7}[/tex] = [tex]\frac{60}{504}[/tex]  This simplified would be [tex]\frac{5}{42}[/tex]  The 5 represent the number of blue marbles available our of 9 total marbles.  Next, we only have 4 blue marbles available out of a total of now 8 marbles and lastly, for the third draw we only have 3 blue marbles available and only 7 total marbles are left.

If the marbles are replaces that changes the problem and the answer would be [tex]\frac{5}{9}[/tex] x [tex]\frac{5}{9}[/tex] x [tex]\frac{5}{9}[/tex] = [tex]\frac{121}{729}[/tex]

Answer:

(8)(-13); -104

Step-by-step explanation:

Product means to mutliply, so the expression is (8)(-13), which evaluates to -104.

Jenna paid a total interest of $4810 (13% of the cost of the car) for the car.

Suppose there is initial amount as P.

The interest, or say charge on it is applied annually as 'C' amount.

Taking how much percent of P is C, we get:

[tex]APR = \dfrac{C}{P} \times 100[/tex]

WE have been given that Jenna bought a new car for $37,000 and paid a 10% down payment and financed the remaining balance for 72 months with an APR of 6.5%

Assuming that she makes monthly payments, to determine the total interest Jenna pays over the life of the loan.

The cost = $37,000

Time = 72 months

APR = 6.5%

Then;

Interest = (37,000 x 6.5 x 2) /100

= $4810

Percentage of interest paid = (4810/37,000 ) x 100

= 13%

Therefore, Jenna paid a total interest of $4810 (13% of the cost of the car) for the car.

The least cost per unit of peanut butter is $0.095 for 20 ounces for ​$1.90 therefore option (B) will be correct.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Division = divide any two numbers or variable called division.

Given the four options of jars;

1) 16 ounces for ​$1.70

Cost per ounces = 1.70/16 = $0.10625

2) 20 ounces for ​$1.90

Cost per ounces = 1.90/20 = $0.095

3) 26 ounces for ​$3.33

Cost per ounce = 3.33/26 = $0.128

The least cost per ounce is $0.095 for 20 ounces for ​$1.90.

Answer:

1. (-1.5,0), -3/2, or -1(1/2)

2.(-16,0)

Step-by-step explanation:

1. explanation:

the 2 and the -5 are 8 spaces apart (-5,-4,-3,-2,-1,0,1,2). the exact halfway point of them is -1.5. the exact halfway point between 5 and -5 is 0. thus led me to (-1.5,0.) I then graphed it on desmos to see if it was halfway, which it is. (refer to the image)

2. explanation:

the distance between -6 and 4 is 10, so -16 would be the first half of the endpoint location. Then the distance between 4 and 8 is 4, so 4-4 is 0. the start point of 2 is (-16,0)

Answer:

x < 0

Step-by-step explanation:

We are given this inequality:

3x + 4 < 4

And we want to solve it.

Solving inequalities is very similar to solving equations. We want to isolate the variable (in this case, x) on one side, while leaving the numbers on the other side.

To start, we can subtract 4 from both sides.

3x + 4 < 4

    -4     -4

__________________

3x < 0

Now, we have the numbers on one side and the variable on the other, but we aren't done yet, as we want to solve for the value of x, or 1x, not the value of 3x.

So, we'll need to divide both sides by 3.

3x < 0

Square both sides to have:

(60-8x)² = (x-9)²

60-8x = x²-18x+81

Equate to zero to have;

x²-18x+81 - 60 + 8x = 0

x² - 10x + 21 = 0

x² -3x-7x +21 = 0

The distance from the check point when Odalis catch up Jaquan is 1.2 kilometers.

Relative speed is the net speed difference when objects move in the same direction and sum of individual speeds when objects move in opposite direction.

Given Jaquan speed is 9km/hr which is 0.15km/minute and Odalis has a speed of 12km/hr which is 0.2km/minute.

∴ The relative speed difference between Jaquan and Odalis is

= (0.2 - 0.15) km/hr.

= 0.05 km/hr.

Given Odalis reached the check post after 2 minutes in this time Jaquan have covered (2×0.15) kilometers.

= 0.30 kilometers.

Now to catch up Jaquan, Odalis will need (0.30/0.05) minutes which is

The approximate rate of change of the function is 224.95

The rate of change of the given function is expressed according to the equation below;

f'(x) = f(b)- f(a)/b-a

Given the interval [-4, 3]

a = -4

b = 3

f(a) = 9(-4)⁴ + 7/(-4)²

f(-4) = 2304+ 7/16

f(-4) = 2304.4375

f(b) = 9(3)⁴ + 7/(3)²

f(3) = 729 + 7/9

f(3) = 729.7778

Substitute to have:

f'(x) = 729.7778-2304.4375/3+4

f'(x) = 1574.65/7

f'(x) = 224.95
