jose' is putting up wallpaper is $1.75 per square foot. one wall measures 10 by 9 feet. how much will wallpaper cost for this wa
Airida [17]
If you are finding the perimeter the answer would be:
$15.50
If you do 9*$1.75=$15.75
If you do 10*$1.75=17.50
When you find perimeter it’s length+length+ width+ width
This gives you $15.50
If you are finding the area the answer would be:
$157.50
To find area you do 10*9=90
Then, you do 90*$1.75=$157.50

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.
