Which equation is the inverse of 2(x – 2)2 = 8(7 + y)? –2(x – 2)2 = –8(7 + y) y = one-fourth x squared minus x minus 6 y = negative 2 plus-or-minus startroot 28 + 4 x endroot y = 2 plus-or-minus startroot 28 + 4 x endroot

Step-by-step explanation:

we have

step 1

Exchange the variables x for y and y for x

step 2

Isolate the variable y

Divide by 2 both sides

square root both sides

Adds 2 both sides

Apply distributive property right side

---> inverse function

y = 2 plus-or-minus StartRoot 28 + 4 x EndRoot

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
