F(-5)=3(-5)+4=-11
g(-2)=4(-2)^2+2=18
Take $1.75 from the $10 then dived the 55cents into the sum. Thus $10 - $1.75 = $8.25. / .55 =15 miles exactly
When Area of rectangle is constant, then the length x is inversely proportional to the width y of the rectangle.

We know that the area of a rectangle is given by the product of the length and width of the rectangle.
Area = Length*Width
In this given problem,
The length of the rerectanglctangle is represented by x
and the width of the rectangle is represented by y
If the area of the rectangle is represented by A now.
So by the formula,
A = x*y
When A is constant then,
x = A/y

So from the above calculation we can conclude that about relation between length and width that,
"When Area of rectangle is constant, then the length x is inversely proportional to the width y of the rectangle."

Mr. chang paid the least because 10% off 25 is more than 20%off 30
I believe the answer is 18, because 5x3=15, so we can only assume that N is 6x3=18.
