Rachel made 6 birdhouses and sold 4 of them for $19 each. Is it reasonable that she had $57 in receipts?

It is not reasonable. She should have $76

Step-by-step explanation:

If Rachel sold 4 birdhouses for $19 each, the amount that she should have received is:

= 19 * 4 birdhouses

= $76

It is therefore not reasonable that she had only $57 in receipts as she should have $76.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
