Can u help me please?

1. x = -15

2. x = 0.25 or x = 1/4

Step-by-step explanation:

1.

8 + 9.8x + 9 = 3.8x - 16 + 3.8x

Simplify both sides

17 + 9.8x = 7.6x - 16

-17                      -17

9.8x = 7.6x - 33

-7.6x   -7.6x

2.2x = -33

Divide by 2.2

x = -15

2.

-2x - 10 = -14x - 7

+7                    +7

-2x - 3 = -14x

+2x         +2x

-3 = -12x

Divide by -12

0.25 = x

x = 0.25 or x = 1/4

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
