Inverse of g(x)=2x -8

The inverse is 1/2x +4

Step-by-step explanation:

g(x)=2x -8

y = 2x-8

Exchange x and y

x = 2y-8

Solve for y

x+8 = 2y-8+8

x+8 = 2y

Divide by 2

1/2 x + 8/2 = 2y/2

1/2x +4 = y

The inverse is 1/2x +4

answer: rolling a number cube and flipping a coin.

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
