Mrs. avery's test for her 1st period class lasted 9 minutes longer than it was supposed to. write an expression for the total amountof time her 1st period took their test if she was supposed to give it for m minutes long.

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

answer: 60%

explanation:

÷

= 60%

okey so the slope is -3/5 and the y -intercept is 7/5

hope this if needed hmu
