Answer:
y = x-4
Step-by-step explanation:
you can put it in a calculator to be sure
64
4 x 10 = 40
4 x 6 = 24
(40)+(24) = 64
Answer: r = 11
Step-by-step explanation:
We know that the point (-2, r) lies on the graph of:
2*x + y = 7.
Then, if we that point is on the graph of the equation, we can replace the values and we will have:
2*(-2) + r = 7
and now we solve this for r-
-4 + r = 7
r = 7 + 4 = 11
r = 11
