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)
1. (x + 5, y - 6) 3/4
2. c
3. b and c
4. b and c
5. c
Answer:
x = 8
Step-by-step explanation:
(please verify) if line segment LM is congruent to line segment PN; then
9x - 25 = 5x + 7; subtract 5x from both sides
4x - 25 = 7; add 25 to both sides
4x = 32; divide by 4
x = 8
Answer:
Part A: S= 24x-72
Part B: S and T are not equivalent for any values of x since when both equations are set equal to 0 they equal different answers. T=.75, while S=3
Step-by-step explanation:
To distribute first you multiply 4 by 6x which equals 24, then you multiply 4 by -18 which gives you -72. Then you the equation together.
