Here are the pairs:
(from the left)
First group: 3rd graph, y = x - 2, table g
Second group: 2nd graph, y = 2x, table b
Third group: 1st graph, y = x + 2, table m
Answer:
x = -15
Step-by-step explanation:
7 - 3x = -4(2+x)
7 - 3x = -8 -4x
7 + x = -8
8/3
(12/15)/(3/10)=(12/15)(10/3)=120/45=8/3
5x 1000
