4|x+3|<8 i need help asap

Likurg_2 [28]

Answer:

-5 <x<-1

Step-by-step explanation:

4|x+3|<8

Divide by 4

4|x+3| /4<8/4

|x+3|<2

There are two solutions one positive and one negative, remember to flip the inequality for the negative

x+3 <2 and x+3 >-2

Subtract 3 from each side

x+3-3 <2-3 and x+3-3 >-2-3

x<-1 and x>-5

-5 <x<-1

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from table

Point (0, 3)

Point (1, 7)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m. Rate of change and slope are the same.

Substitute [SF]: $m=\frac{7-3}{1-0}$
Subtract: $m=\frac{4}{1}$
Divide: $m=4$
