She should multiply y = x - 2 by -4...that way one x will be -4x and the other will be 4x and they will cancel out when added.
answer is -4
Answer:
1. y = 5x + 20
2. $20 the amount you saved mowing your aunt's lawn.
3. 21 weeks
Step-by-step explanation:
1. 5 is the slope because it is the rate. 20 is the y-intercept because that is how much you already have.
2. 20 because that is how much you already have.
3. Since you already have $20, you need to subtract 125 by 20 to get 105. Then you divide 105 by 5 to get 21 weeks.
(-5/3)•(-6/1)=(30/3)
(30/3) simplified is (10/1)
Answer:
28 ft squared
Step-by-step explanation:
The 4 sides of a square are equal in length, so if the perimeter is 20ft that means each side would have to be 5ft, (20/4 = 5). If you increase the length by 2ft, one of the sides would now become 7ft (5+2 = 7). If you decrease the length of the other side by 1ft, the length would now be 4ft (5-1=4). Now to find the area, all you have to do is length * width. So you would do 7ft*4ft which is 28ft squared.
