1. solve for x. show each step. 4(8-x)+36=102-6x 2. solve for d. show each step. d (e – f) = g

1. (1st step): 32-4x+36=102-6x32−4x+36=102−6x, (2nd Step):−4x+68=102−6x, (3)−4x=102−6x−68, (4): −4x=−6x+34, (5): −4x+6x=34, (6): 2x=34, (7): x=34/2, (8): x=17.

2.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
