Translate into an algebraic expression: 22 decreased by y%

We have to decrease 22 by y%.

First we need to calculate what is y% of 22. y% of 22 simply means y% into 22 i.e.

y% x 22

= 0.01(y) x 22

= 0.22y

So 0.22 y is the y% of 22. Now we have to decrease 22 by its y% which becomes:

22 - y% of 22

= 22 - 0.22y

This expression can also be written as:

22 ( 1 - 0.01y)

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.
