Average rate of change, Correct Answer is (0,-3)
Answer:
(3x3) /9
Step-by-step explanation:
first you triple the three (3x3) then divide by 9
x+y = 47
x-y = 21
------------ add together
2x =68 divide by 2
x=34
x+y = 47
34+ y = 47
subtract 34 from each side
y = 13
the two numbers are 34 and 13
I’m not entirely sure, but i do think it could be B.
