Solve the real-world situation by using the substitution method.
the length of a rectangular room is 7 feet more than its width. the perimeter of the room is 70 feet.
let l represent the length of the room and w represent the width in centimeters.
l=w +7
the system of equations
70 = 2 + 2w cano
can be used to represent this situation.
what are the room's dimensions?

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

multiple all that

step-by-step explanation:

27×17

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
