what is the value of the constant in the equation that relates the height and width of this rectangle
Doss [256]

The correct answer is C. 1.5

You can find this answer by using any of the points on the graph and putting them into the given equation. Then you can solve for the constant. For the purpose of this example, we will use (10, 15)

Height = Constant * Width ---> Plug in known values.

15 = Constant * 10 ----> Divide both sides by 10

1.5 = Constant

This will work with whatever numbers you use from the graph. Although this graph does not have any others to really choose from.

I need help on this question
melisa1 [442]

Answer:

C. y = 8x

Step-by-step explanation:

Using the slope formula, we can calculate the rate of Marisol's and Timothy's Machines.

m = \frac{y_1-y_2}{x_1-x_2}

Marisol:

m = \frac{18-12}{3-2} \\m=6

Timothy:

m=\frac{54-36}{6-4} \\m=\frac{18}{2} \\m=9

Now that we know the rate of their machines, we need to choose a rate that is between 6 and 9. Therefore, the rate of Zorian's machine needs to be y = 8x.

Need help which one is it <br> a)x=7<br> b)x=12<br> c)x=20
Svetach [21]

- you can use the pythagorean theorem for this.

a^2 + b^2 = c^2

12^2 + 16^2 = c^2

144 + 256 = c^2

400 = c^2

- square root this.

c = 20

therefore, x = 20.

so option C.
