What is the solution to the inequality 0.8x+20< 1.2x−40?
a
x< −30

b
x> 150

c
x> −30

d
19860

0.8x-1.2x < -20 - 40

-0.4x < -60

if you get ride of minus sign on both sides you have to flip the < sign so

0.4x>60

X>60/0.4

X>150

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
