Answer:
y = -(x -3)^2 +2
Step-by-step explanation:
The vertex form of the equation for a parabola is ...
y = a(x -h)^2 +k
where the vertex is (h, k) and the value 'a' is a vertical scale factor.
The value of 'a' can be found by looking at the y-value of points ±1 either side of the vertex relative to the vertex. Here, the vertex y-value is +2 at x=3, and either side goes down 1 unit (to y=1) for 1 unit to the right or left. So, a = -1.
Using the values we've read from the graph for the vertex (h, k) = (3, 2) and the scale factor a = -1, we can write the equation as ...
y = -(x -3)^2 +2
Well you really don't have to do any work, as you can see D) you have the 40 hours he need minus the one he already did. 40 - (food bank + hospital)
Answer: D)
Hope I helped
Answer:
10(1+2x)
Step-by-step explanation:
When factoring you'd take out the greatest common factor, that being ten for this problem. The greatest common factor would go on the outside of your parenthesis. What remains after dividing the greatest common factor would go on the inside of the parenthesis.
