PLEASE HELP VERY URGENT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

j. 18 inches

Explanation:

Answer 2

Q1. Look at the picture.

`C.\\y=-(1)/(3)x+3\\\\y=2x-4`

Q2. Look at the picture.

`A.\ 4-t`

Q3.

Put the value of x = 2 to the equation 3x + y = 5:

`3(2)+y=5`

`6+y=5` subtract 6 from both sides

`y=-1\\\\F.\ -1`

Q4.

`\left\{\begin{array}{ccc}n=3m-11&(*)\\2m+3n=0&(**)\end{array}\right`

Substitute (*) to (**):

`2m+3(3m-11)=0` use distributive property

`2m+(3)(3m)+(3)(-11)=0`

`2m+9m-33=0` add 33 to both sides

`11m=33` divide both sides by 11

`m=3`

Put the value of m to (*):

`n=3(3)-11\\\\n=9-11\\\\n=-2`

`C. (3,\ -2)`

Q5.

w - width

3w - length

24 in - the sum of length and width

The equation:

`w+3w=24`

`4w=24` divide both sides by 4

`w=6\ in`

`3w=3(6)=18\ in`

`J.\ 18\ inches`
