Answer:

(r*s) = (x-5)(2x+6) = 2x2 + 6x - 10x - 30 = 2x2 - 4x - 30

(r-s)(x) = x-5 - (2x+6) = x - 5 - 2x - 6 = -x - 11

(r+s)(x) = x - 5 + 2x + 6 = 3x + 1

(r + s)(3) = 3(3) + 1 = 9 + 1 = 10

Answer:

$y=\frac{1}{2}x$

Step-by-step explanation:

To find the inverse of a function, switch the x and y values and isolate y. After switching the x and y values of $y=2x$ , we get $x=2y$ .

Now divide by 2 to isolate y:

$y=\frac{x}{2},\\\boxed{y=\frac{1}{2}x}$
