Match each inequality to the number line that represents its solution

Part 1)  shaded area at left of x=8 (close circle) --->  

Part 2) shaded area at left of x=-5 (close circle) --->

Part 3) shaded area at left of x=-6 (close circle) --->

Part 4) shaded area at left of x=7 (close circle) --->

see the attached figure

Step-by-step explanation:

Part 1) we have

Multiply by -10 both sides

Adds 2 both sides

The solution is the interval -----> (-∞,8]

All real numbers less than or equal to 8

In a number line the solution is the shaded area at left of x=8 (close circle)

Part 2) we have

Multiply by -6 both sides

Subtract 11 both sides

Divide by 100 both sides

The solution is the interval -----> (-∞,-5]

All real numbers less than or equal to -5

In a number line the solution is the shaded area at left of x=-5 (close circle)

Part 3) we have

Multiply by 2 both sides

Subtract 210 both sides

Divide by 3 both sides

The solution is the interval -----> (-∞,-6]

All real numbers less than or equal to -6

In a number line the solution is the shaded area at left of x=-6 (close circle)

Part 4) we have

Multiply by -18 both sides

Adds 10 both sides

Divide by 13 both sides

The solution is the interval -----> (-∞,7]

All real numbers less than or equal to 7

In a number line the solution is the shaded area at left of x=7 (close circle)

i would say c is the best answer, hope it's right!

good luck! =)

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
