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

Answer:
True
Step-by-step explanation:
We have two salaries:
My salary is A
Your salary is B
If I earn 60% more than you
This means that
You must earn 37.5% less than me
The ratio between your salary and mine is:
Your salary is 62.5% of mine. So you earn 100-62.5 = 37.5%. So this is true.

Solve The Division Problems First:
2 Divided By 5
= 0.4
1 Divided By 8
= 0.125
Compare; Which Is Larger:
V
0.125 0.4
0.4 > 0.125
If you were to graph these two numbers on a number line, you would find that 0.4 is closer to zero, making it the largest number of the two.
