The value of y varies directly with x and y=12 when x=-6 find y when x=-4
FinnZ [79.3K]

Answer:

B)8

Step-by-step explanation:

That is the right answer because when y=12,  x=-6

12/-6 = -2

This means that x = y/-2

or y = x * -2

-4 * -2 = 8

Answer:

  They are not commutative, because f(g(x)) and g(f(x) are not equal.

Step-by-step explanation:

In order for the composition of the functions to be commutative, we must have ...

  f(g(x)) ≡ g(f(x))

for all values of x.

Here, we have f(g(x)) = 1 and g(f(x)) = 2. f(g(x)) and g(f(x)) are not equal, so the composition of the functions is not commutative.

To solve this question you would first multiply all the dimensions of the pillar together. That would be:

2.5 x 2.5 x 12 = 75 square feet

Then you take the weight of the pillar and divide it by the amount of square feet:

12,000 / 75 = 160 pounds per square foot.
