Answer:
y < - 12
Step-by-step explanation:
y + 15 < 3 ( subtract 15 from both sides )
y < - 12
Answer:
we need a picture...
Step-by-step explanation:
Answer:
The value is Approximately 56
y varies directly with x.
The constant of variation is k = 7
Step-by-step explanation:
We have to check whether both vary directly with each other or not.
Every pair of x and y will be considered one by one
If y varies directly with x, it should satisfy y = kx or k = yx
So,
For x= -2, y=-14

For
x=3, y=21

For
x=5, y=35

As k is same for all pairs of x and y, it can be concluded that:
y varies directly with x.
The constant of variation is k = 7
