Step-by-step explanation:

did them as fast i could

Answer 1.)

⇒ 4x - 15 + 2x = x +20

⇒ 6x -15 = x +20

⇒ 5x = 35

⇒ x = 7

Answer 2.)

⇒ 2(2x−5)=20−x

⇒ 4x - 10 = 20 - x

⇒ 5x = 30

⇒ x = 6

Answer 3.)

⇒ 3−4x=10x+10

⇒ 14x = -7

⇒ x = -1/2

Answer 4.)

⇒ 4(2x−1)=−10(x−5)

⇒ 8x - 4 = -10x + 50

⇒ 18x = 54

⇒ x = 3

Answer 5.)

⇒ 5/3 = 6/x + 2

⇒ x = -18

Answer 6.)

⇒ x - 7/5 = -3

⇒ x = -8/5

Answer 7.)

⇒ 4/5x - 3 = 2/3x + 5

⇒ 12x - 10x = 120

⇒ x = 60

Answer 8.)

⇒ 6x − 3 = 2 + 4x − 11

⇒ 2x = -6

⇒ x = -3

Answer 9.)

⇒ 3 − (4−x) = 5 + 3(x−4)

⇒ 3 - 4 + x = 5 + 3x - 4

⇒ -1 + x = 1 +3x

⇒ x = -1

Answer 10.)

⇒ 10 + 5x − 2 = 2 − 3x + 6

⇒ 8 + 5x = 8 - 3x

⇒ x = 0

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)
