A. No because -2*-3=6
B. No because if you plug in 5 it will be 1-2(5) which equals -9
C. No because when you plug in -4 it will be 4+6(-4) which equals to -20
Answer:
2 days
Step-by-step explanation:
70 miles x
————— = ———-
1 hour 14 hours
Cross multiply.
70 • 14 = x
980 = x
Alejandra drove 980 miles.
Answer:
x = 3y + 1
Step-by-step explanation:
You need to find the relationship between x and y before finding the y-intercept.
0-(-1) = 1
1-0 = 1
2-1 = 1
1-(-2) = 3
4-1 = 3
7-4 = 3
As x increases by 1, y increases by 3.
At x = 0, y is already 1. Thus:
x = 3y + 1
