Answer:
No
Step-by-step explanation:
No, because the perimeter of a rectangle is 2(x+y). Justin added the sides. Then he should have multiplied by 2 but he didn't so Justin is incorrect.

Answer:
2x + 3(8 - 3x) = 3
x = 3
y = -1
Step-by-step explanation:
2x + 3y = 3
y = 8 – 3x
2x + 3(8 - 3x) = 3
2x + 24 - 9x = 3
7x = 21
x = 3
y = 8 - 3(3)
y = -1
Answer:
Step-by-step explanation:
We know that , the equation of a line that passes through (a,b) and (c,d) is given by :_
![(y-b)=\dfrac{d-b}{c-a}(x-a)](https://tex.z-dn.net/?f=%28y-b%29%3D%5Cdfrac%7Bd-b%7D%7Bc-a%7D%28x-a%29)
Standard form of equation of line = ![Ax+By=C](https://tex.z-dn.net/?f=Ax%2BBy%3DC)
Given points = (7, -3) and (4, -8)
Then, the equation of a line that passes through the points . (7, -3) and (4, -8) is given by -
![(y-(-3))=\dfrac{-8-(-3)}{4-7}(x-7)](https://tex.z-dn.net/?f=%28y-%28-3%29%29%3D%5Cdfrac%7B-8-%28-3%29%7D%7B4-7%7D%28x-7%29)
[∵ (-)(-)=(+)]
Or
Hence, the required equation :-
The answer is D

Answer:
y = -2/3 + 18
Step-by-step explanation:
2x + 3y = 18 ----- here is the equation...
-2x - 2x ----- bring the 2x to the other side
3y = -2x + 18 ----- now you have to divide everything by 3 to get y by itself
y = -2/3 + 18 ----- Done!
