Question

Please answer quickly, it’s inequalities and it’s very confusing.

Answer 1

Answer:

A

Step-by-step explanation:

It is A, because it tells you the equation of

-5x + 8 ≥ -7

Because the key on the right tells you that shaded squares are negative and white ones are positive.

You can then subtract both sides by 8 to isolate the -5x and the equation becomes:

-5x ≥ -7 - 8

Which simplifies to

-5x ≥ -15

which you can now divide both sides by -5 to get

x ≥ 3

BUT WAIT

the general rule is that when you divide a variable (in this case x) by a negative number, you have to flip the inequality sign

so ≥

should become ≤

so the equation is x ≤ 3
