Answer:
None of the above. -4x - 32
Step-by-step explanation:
-4(X + 8)
Distribute -4
-4x + 32 (8 × 4 =32)

Answer:
see attached
Step-by-step explanation:
The equation can be rewritten to vertex form, so you can tell the vertex is at (2, -5). The leading coefficient of 2 means the points will be twice as far apart vertically than they would be if the leading coefficient were 1. A couple of points are shown in the attached.
y = 2(x^2 -4x) +3
y = 2(x^2 -4x +4) +3 -8 . . . . . . complete the square
y = 2(x -2)^2 -5 . . . . . . . . . . . . finish putting in vertex form
Answer:
The endpoint, B, is (-7, -8)
Step-by-step explanation:
When I get a problem like this, the first thing I like to do is find the difference between the midpoint and the starting point.
In this problem it would be -5 - -3 = -2 and -2 - 4 = -6.
(-2, -6) is what will help us find the endpoint.
Take the midpoint, (-5, -2), and add those coordinates to it.
-5 + -2 = -7
-2 + -6 = -8
So our endpoint is (-7, -8)
Here is a graph, to help you visualize it.
Answer:
19 hours
Step-by-step explanation:
You have 279. First, devide the 279 by 9(dollar amount).
279/9 = 31
So combined they work 31 hours. Subtract 7 from this, since we know Katya worked 7 extra hours. Youll now have 24. (31-7 = 24)
Next, divide this number in half, which will get you what they both worked before Katya worked an extra 7 hours.
24/2 = 12.
Now that we know they both worked 12 hours, we can just add back the 7 hours Katya worked.
12+7 = 19.
So the answer to how many hours katya worked will be:
<u>19 hours</u>
