Answer:
A. y<-3
Step-by-step explanation:
They are not parallel because the slopes are different (slope of 4 and slope of 0.25)
Neither are they perpendicular. If they were then m1*m2 ( the product of their slopes) would be -1 ). The product of these slopes = 4*0.25 = 1)
So choice A is the correct one.
Answer:
3.5
Step-by-step explanation:
If you multiply 3.5 for example by 2 (which is the number of gallons) you get 7 which is the cost (also a proportional relationship).
\left[x \right] = \left[ \frac{13}{6}\right][x]=[613]
totally answer
7 - 2 (7) -8
7 - 14 - 8
7-14= -7
-7 - 8 = - 15
