The two functions are inverses.
Step-by-step explanation:
We are supposed to find whether the two functions are inverses.
To find the inverse of f(x)
y = 5x+4
y-4=5x
Replace x with y and y with x
So,
So,
So,The two functions are inverses.
Answer:
x = 5
Step-by-step explanation:
The sum of the side lengths shown is ...
(2x) + (3x +2) + (4x +1) = 9x +3
That is the perimeter of the inscribed triangle. That triangle is similar to triangle ABC by a scale factor of 1:2, so the perimeter of ΔABC is ...
2(9x +3) = 96 = 18x +6
90 = 18x . . . . subtract 6
90/18 = x = 5 . . . . . divide by the coefficient of x
