Solve the Answer for x.
56 < 7(7-x)

Step-by-step explanation:

Step 1:  Distribute

Step 2:  Subtract 49 from both sides

Step 3:  Divide both sides by -7

Since you divided by a negative, you must flip the sign.

Steps to solve:

56 < 7(7 - x)

~Distributive Property

56 < (7*7) + (7*-x)

~Simplify

56 < 49 - 7x

~Subtract 49 to both sides

56 - 49 < 49 - 49 - 7x

~Simplify

7 < -7x

~Divide 7 to both sides

7/-7 < 7x/-7

~Simplify

-1 > x

Best of Luck!

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.
