Answer:
the slope is -4/5 and the y-intercept is 0
Step-by-step explanation:
Answer:
The value of m is 1000 for r=5
Step-by-step explanation:
Given that m is proportional to the cube of r
It can be written as:

When the proportionality symbol is removed a proportionality constant is introduced in the equation.
Let k be the proportionality constant

Given
r=3,m=216
Putting the values

The equation will now become

Putting r = 5

Hence,
The value of m is 1000 for r=5
396 divided by 12 will be 33
No she is not correct if she said 200+20+23 was the same as 200+40+3 she would have been correct.
