Answer:
x = 2
Step-by-step explanation:
Rearrange terms
Subtract from both sides of the equation
Simplify
Divide both sides of the equation by the same term
Simplify

Answer:
and
do not lie on the line
Step-by-step explanation:
Given

Required
Determine which points that are not on the line
First, we need to determine the slope (m) of the line:

Where


So;



Next, we determine the line equation using:

Where


becomes


To determine which point is on the line, we simply plug in the values of x to in the equation check.

Answer
so whats the question?
Step-by-step explanation:
is there a value to y? if not, this is what I got:
Y^2 + 2y + 3
Let the width be x cm.
Then length=3x-4 cm.
Its perimeter is 64 cm.
We know that perimeter of a rectangle= 2(length+width)
So,
2(3x-4+x)=64
6x-8+2x=64
6x+2x=64+8
8x=72
x=9
Therefore,
length=(3×9-4)cm=(27-4)cm=23 cm.
Width=9 cm.
