<em><u>Question:</u></em>
If y varies inversely with the square of r, what is the constant of proportionality when y =10 and r = 5?
<em><u>Answer:</u></em>
The constant of proportionality is 250
<em><u>Solution:</u></em>
Given that,
y varies inversely with the square of r
Which means,

Where, "k" is constant of proportionality
Subtitute y = 10 and r = 5

Thus the constant of proportionality is 250
The answer should be the last one D
1) add 8x on both sides
3y=12+8x
2)divide by 3 to solve for y
y=4+8/3x
y=8/3x+4
8/3x is the slope, 4 is the y-intercept
Answer:
<h2>x = 1/4 and y = -2</h2>
