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.
