Positive correlation, likely causal
Answer is A
Step-by-step explanation:
Answer:
1) y= 2x-4
2) y= 2/3 - 3
3) y=1/2x+2
4) y=-4x-4
Step-by-step explanation:
all you basically has to do is is subtract the x to isolate the y and if the y and if the y still has a number by it you use it to decide it
Up to 100, the common multiples of 3 and 7 are 21, 42, and 63
12-12x+7=100
-12x+19=100
-12x=81
x=-27/4
