If i'm not wrong its distributing property of addition. <span />
Answer:-74
Step-by-step explanation: When you are in the megatives, less is more! So -74 is actually greater then -75
Equation is y=kx. We have four chance to figure out k; hopefully they all give the same result
x=9, y=63, y=kx becomes 63=k(9) so k=63/9=7
x=4, y=28, 28=k(4), k=7
The constant of proportionality is 7; we check 2×7=14, 11×7=77
Answer: k=7, y=7x
The answer is 0.6 because you divide 21 by 35 and get 0.6
