Vertex form for a parabola with vertex (p,q) is
We have (p,q)=(-4,5) and another point (-3,2) so we can solve for <em>a:</em>
Putting it together,
Answer: 
We could multiply that out if we like but I won't bother.
Answer:
y=2x-2
Step-by-step explanation:
<em>the slope is y/x</em>
the slope is 2 or 2/1
<em>subtract 2 from the y value and 1 from the x value</em>
(3-1,4-2) = (2,2)
<em>keep doing this until you get a 0 in the x value</em>
(2-1,2-2) = (1,0)
<em>1 is your x-intercept</em>
(1-1,0-2) = (0,-2)
-2 is your y intercept.
So now you know your y-intercept and your slope so you can now write your equation.
<em>y=mx+b</em>
<em>m=slope, b=y-intercept</em>
m=2, b=-2
<em>substitute into the equation</em>
y=2x-2
Subtract 5x from both sides
0=-30x
Divide both sides by -30
0=x
Final answer: x=0
Hope this helps!
Say x is 1 1^2=1 4x=4 4*1=4 I believe that is what you were asking
Answer:
x = 2
Step-by-step explanation:
OK so lets do it together.
2x = -2x + 8
Subtract 8 from both sides
2x - 8 = -2x
Add 2x to both sides
4x - 8 = 0
Add 8 to both sides
4x = 8
Divide each side by 4
x = 2
Check:
4 = -4 + 8
4 = 4
correct
