Answer:
F=89
Step-by-step explanation:
Answer:
V= 64 ft^3
Step-by-step explanation:
The volume of a pyramide is given by the formula
V = 1/3 l*w*h
Given the l = 8 w = 4 and h = 6
V = 1/3 ( 8*4*6)
V = 1/3 ( 192)
V= 64 ft^3
Answer:
b. -x + y = 0
Step-by-step explanation:

<u>Direct variation</u>:
Direct variation means "y varies directly as x”:
where k is the (non-zero) constant of variation.
To determine which of the given equations represents a direct variation, isolate y for each and compare with the <u>direct variation equation</u>.
<u>Equation a</u>
This is not a direct variation equation as there is an addition of -2.
<u>Equation b</u>
This is a direct variation equation where the constant of variation is 1.
<u>Equation c</u>
This is not a direct variation equation as y is <u>inversely proportional</u> to x.
<u>Equation d</u>
This equation does not include the variable x, and so is therefore not a direct variation equation.
