Find the inverse of y=1/2x+6

Mathematics
1 answer:
Komok [63]3 years ago
3 0

Answer:

y = 2x - 12

Step-by-step explanation:

We want to find the inverse of

y =  \frac{1}{2}x + 6

We interchange x and y.

x =  \frac{1}{2}y + 6

We need to solve for y, so let us multiply through by 2.

2x = y + 12

Subtract 6 from both sides.

y = 2x - 12

Therefore the required inverse is

y = 2x  - 12

Given the function g(x) = (5 - x)^3 , what is the value of g(2)?
11111nata11111 [884]

Answer:

g(2) = 27 is the answer.

Step-by-step explanation:

If the function is g(x) = (5 - x)³

By expanding (5 - x)³ = 5³-3.5²x + 15x² -x³

g(x) = 125 - 75x + 15x² - x³

Now g(2) = 125 - 75×2 + 15×(2)² - 2³

        g(2) = 125 - 150 + 60 - 8

               = -25 + 60 - 8

              = 35 - 8 = 27

Or directly putting the value x = 2 in g(x) we get

g(2) = (5 - 2)³ = 3³ = 27

Therefore g(2) = 27 is the answer.
