A ; C ; D
Step-by-step explanation:
Volume of a rectangular prism:
V = l x w x h
1) 5 x 4 x 3 = 60 (ok)
2) 25 x 20 x 15. The result is > 60
3) 5 x 2 x 6 = 60 (ok)
4) 4 x 1 x 15 = 60 (ok)
5) 5 x 8 x 2 = 80
Answer:
x=0
Step-by-step explanation:
Answer:
y = 1.25
Step-by-step explanation:
Use the direct variation equation y = kx, and solve for k:
y = kx
-10 = k(40)
-0.25 = k
So, the equation is y = -0.25x. Solve for y when x = -5
y = -0.25x
y = -0.25(-5)
y = 1.25
So, y = 1.25 when x = -5
