A triangular prism Vol. = area (A) of the triangular base × height (h) of prism
A triangular pyramid V = A × 1/3 h
So since they have same base A and h, the V of the pyramid will be exactly 1/3 the V of the prism
Let x = Wally's age now
Then, 3x = Jose's age now
Wally's age 5 years from now = x+5
Jose's age 5 years from now = 3x+5
(x+5) + (3x+5) = 42
4x + 10 = 42
4x = 32 x = 8
Wally is 8 years old and Jose is 24.
Hi there!
First replace m(x) by y.
To find the inverse function we must switch the places from the variables x and y.
Now we need to isolate the y again to find the formula of the inverse function. First add 5 to both sides.
Switch sides.
And finally divide both sides by 5.
And therefore we can conclude the following:
The answer is C.
~ Hope this helps you!
