Question

I need to know the answer so I can correct it so I can fully retake my test

Answer 1

Explanation:

4(x+3) - 7 ≥ x + 3(x + 1)

4x + 12 -7 ≥ x + 3x + 3

5≥3

so this answer tells us that this equation will always be true no matter what number you plug in for x ... so all real numbers works

Answer 2

D. all real numbers

Explanation:

4(x+3)-7greater than or equal to x+3(x+1)

4x+12-7> or equal to x+3x+3

4x+5>or equal to 4x+3

so, by testing

if x=1, is it true that 4x+5 is greater than or equal to 4x+3

4(1)+5=4(1)+3

9=7

hence it true 9 is greater than 7

Option D is collect
