Answer:

Last option.

Step-by-step explanation:

12 is not less than or equal to the value of 10.

Since x is equal to 8, you add 4 with 8 and get 12 on the left side.

Answer:

x+4 [tex]\leq[/tex] 10

Step-by-step explanation:

Let's test 8 as a solution, and see which one is false. This will be the answer, since we are looking for the inequality where x=8 is not a solution.

4x+3 >0

Substitute 8 in for x

4(8)+3>0

Multiply

32+3>0

Add

35>0

This is true. 35 is greater than 0, so this is not the answer

72/8 [tex]\geq[/tex] 4

Substitute 8 in for x

72/8 [tex]\geq[/tex]  4

Divide

9  [tex]\geq[/tex] 4

This is true. 9 is greater than 4, so this is not the answer

9x-5 < 100

Substitute 8 in for x

9(8)-5 < 100

Multiply

72-5 <100

Subtract

67 <100

This is true. 67 is less than 100, so this is not the answer.

x+4 [tex]\leq[/tex] 10

Substitute 8 in for x

8+4 [tex]\leq[/tex] 10  

Add

12 [tex]\leq[/tex]10

This is not true. 12 is not less than 10, so this is the correct choice.
