P = -23 + 0.13y
For y = 350:
p = -23 + 0.13(350) = -23 + 45.5 = 22.5
For y = 400:
p = -23 + 0.13(400) = -23 + 52 = 29
For y = 450:
p = -23 + 0.13(450) = -23 + 58.5 = 35.5
Hello!
Use the slope formula to determine the slope between the points:
m = (y2 - y1) / (x2 - x1)
Plug in the values:
m = (7 - 2) / (10 - 5)
m = 5 / 5
m = 1
Answer:
A
Step-by-step explanation:
You literally just have to use a calc or solve it by yourself. Doesn't need a graph.
-2x + 3 = 3x - 2 (-3 and -x create positive)
-5x + 3 = -2 (subtract 3x from both sides)
-5x = -5
x= 1
To determine how much sand she needs, we need the area of the garage
The area can be found by multiplying the width and the length
A = 36 x 20
A = 1080 feet
Now we multiply the area by the volume (2 inches of sand)
1080 * 2 = 2160
Siobhan needs 2160 feet of sand
