If f(x) and f -1 (x) are inverse functions of each other and f(x) = 2x+5, what is f -1 (8)?
Aleksandr [31]

Answer: 3/2

Step-by-step explanation:

The first one: y=2x+5

X=2y+5.Then solve for y after switching x and y

X-5=2y, X-5/2=y

Since F-1= X-5/ 2, we plug the value of X in

8-5/2, so it should be 3/2

Please help again thank you in advance
mojhsa [17]

Answer:

20 units

Step-by-step explanation:

Since the triangle is equilateral then all 3 sides are equal in length.

Equate any 2 sides and solve for x

4x = 3x + 5 ( subtract 3x from both sides )

x = 5

hence

4x = 4 × 5 = 20

3x + 5 = (3 × 5) + 5 = 15 + 5 = 20

7x - 15 = (7 × 5) - 15 = 35 - 15 = 20

The lengths of the sides are 20 units
