Set 2x=x²-3 to each other.
Subtract 2x from both sides and get the following
x²-3-2x
Rearranging the formula to make factoring easier, we get
x²-2x-3
Factor and you should get the following:
(x-3)(x+1)
set both equal to 0 and solve for x.
x-3=0⇒x=3
x+1=0⇒x=-1
Now plug both of these values back into one of your original equations to get your y-values. It does not matter which equation you plug your xs back into due to the fact they intersect at the same x, and thus will also intersect at the same y.
For times sake,
y=2x
plug in x=3 and get y=6
plug in x=-1 and get y=-2
Ergo, the equations y=2x and y=x²-3 intersect at
(3,6) and (-1,-2)
Graph is incorrect.
Find points (x,y)
If x=#, what does y=?
Example:
Y=5x+4
Y=5•0+4
Y=0+4
Y=4
Points:
(0,4)
(-1,1)
(-2,-6)
Also, only draw the line in areas where x≤0
Meaning nothing should be on the right half of the square.
The range means what Y values are possible?
When draw properly, with nothing on the right half, the highest Y value will be 4.
So, the range is y≤4
Answer:
No, because the correlation coefficient is closer to 0 than to 1, which indicates a weak association between the variables.

<span>90 + 35 = 125.
180 -125 = 55 degrees.
4.59^2 + 6.55^2 = 8^2
21.1 + 42.9= 64 inches</span>
