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

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

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
