+60 two negatives equal a positive
Yes. For example, 25. The square root of 25 is 5 because 5*5=25. Multiplying two negatives always= a positive, so -5*-5=25.
Answer:
y=3/4m
Step-by-step explanation:
All proportional relationships have the form y=mx where m is the rate of change from the families donations x to the business donations y. We can find the rate of change m by substituting values we already know. We know when x=$12 then y=$9.
9=m*12
We solve for m by dividing by 12 on both sides.
m=9/12
This simplifies to 3/4 so
m=9/12=3/4.
The equation is y=3/4m
8 * 54 = 8 * 50 + 8 * 4 = 8(50 + 4)
