Answer:
See below.
Step-by-step explanation:
For y = a(x - b)^2 + c , the vertex is at (b, c) and the axis of symmetry is x = b.
So for y = (x-2)^2 - 2,
the vertex is (2, -2) and the axis of symmetry is x = 2.
Answer:
0,3
Step-by-step explanation:
(-3+3)/2, (6+0)/2
If there is no number in between sets of numbers, it's going to be multiplication.
So (w+2) x (w+7)
w+2, well, evaluates into w+2.
w+7 is w+7.
We'll use the FOIL method for this.
FOIL stands for:
First
Outer
Inner
Last
Let's start with the first terms. Multiply them.
So: w * w.
Combine both w's, and you get
.
Now multiply the outer terms.
w * 7 = 7w.
Then the inner terms. 2 and w.
2 x w = 2w.
So our current numbers are:
, 7w, and 2w.
We can add 7w and 2w together.
7w + 2w = 9w.
Now multiply the last terms.
2 x 7 = 14.
So, this simplifies to
Hope this helped!
Answer: D 30%
Step-by-step explanation:amount change/amount start x 100%
(20-14)/20=.3
.3 x 100% = 30%
