Justify each step 2x-5=-20 2x=-15 x=-15/2

First step had applied the addition property of equality, which states that whatever you add on one side of an equation you must add to the other side. In this case, 5 was added to both sides to cancel out -5.

And next step had applied the division property of equality, which states that whatever you divide on one side of an equation you must divide on the other side. In this case, 2 was divided on both sides to isolate x.

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
