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
The only numbers I could think of would be 1, 2, and 4 because 4 is greater than 3 (2+1) and four times greater than 1 (2-1)
7y + 10x = 99
y - x = 2
y = 7 , x = 5
we have: -10/4 = -2.5 ⇒ -2 > -2.5 > -3
ANSWER : -2 and -3
ok done. Thank to me :>
Answer:
A
Step-by-step explanation:
Just put x = 80 and y = 210 into the equation...
or put x = 40, y = 90.
A:
210 - 90 = 3(80-40)
120 = 120√
B:
210 + 90 = 3(80+40)
300 = 360×
C:
210 - 90 = 2.6(80-40)
120 = 104×
D:
210 + 90 = 2.6(80+40)
300 = 312×
