Answer:
See below
Step-by-step explanation:
Using formula
- x^2 - y^2 = (x + y)(x - y)
Applying to given expression
- 36 - 9 =
- 6^2 - 3^2=
- (6 + 3)(6 - 3)=
- 9*3=
- 27
Y=2(x-3)^2 +7 would be the way to rewrite this equation in vertex form.
Answer:
Only x=-2 is an extraneous solution is the answer
Step-by-step explanation:
Answer:
Step-by-step explanation:
First you have to find the slope
M= y2-y1/ x2-x1.
6-4 / 8-7 = 2/1 or 2
Then you pick one set of coordinates and plug the information into the formula. It doesn't matter which set you use as long as you plug the information in correctly.
I will choose (6,4)
Slope intercept formula is y-y1 =m(x-x1)
Y-4=2(x-6)
Then you simplify.
Y-4=2x-12
+4. +4
Y=2x-8 is your solution.
X + 2 > 3x - 8
subtract x from both sides
2 > 2x - 8
add 8 to both sides
10 > 2x
divide both sides by 2
5 > x
ANSWER: 5 > x
Hope this helps! :)
