April and Amy have a combination age oh 53.Amy is 9 years younger than April.what are April and Amy ages.
Lostsunrise [7]

If the total age of both April and Amy are 53

And Amy is 9 years younger than april.

Then to solve for Amy's age you would subtract 9 from 53 and divide by 2

which equals 22

Since amy is 9 years younger than April, then April's age is Amy's age 22 + 9 which gives you 31

April's age is 31 and Amy's age is 22

When comparing the slopes of the functions you must first make y the subject of formula.

6x - y - 2 = 0 => y = 6x - 2 => slope is 6

2y = 3/2 x + 6 => y = 3/4 x + 3 => slpoe = 3/4

5 = 2x + 4y - 3 => 4y = -2x + 5 + 3 = -2x + 8 => y = -1/2 x + 2 => slope = -1/2

The first function is steepest followed by the second function and then the third function.

The slope is not affected by the y-intercept neither is the y-intercept affected by the slope.
