Answer:

-½(30) = -15

Step-by-step explanation:

Marta's pool decrees ½ inch each day, so that would be -½ each day. You would take that -½ and multiply it by 30 so you can find out the decrees in inches over 30 days so the equation would be -½ × 30 = -15 (im sorry if that didn't make sense)

Answer:

3x - y = - 15

Ax + By = C ( A is a positive integer and B, C are integers )

rearrange y = 3x + 15 into this form

subtract y from both sides

0 = 3x - y + 15 ( subtract 15 from both sides )
