Answer:
-2.50
Step-by-step explanation:
3 is closer to 0then 10
2600 increased by 3%
there are 2 ways to do this...
(1) 2600 + 0.03(2600) = 2600 + 78 = 2678 per quarter
or
(2) 2600 * 1.03 = 2678 per quarter
Completing the square has us breaking rules of solving equations and factoring out the greatest common factor, but it is what it is! The first step is to make sure that the coefficient on the x^2 term is a 1 and it is so we are good there. Now subtract 9 from both sides to get x^2 + 16x = -9. Complete the square on the left side by taking half of the linear term (16x) which is 8 and then squaring it to get 64. That's what is added to both sides. Now it looks like this:
x^2 + 16x + 64 = -9 + 64. If you were to write it in vertex form it would look like this: (x+8)^2 - 55 = 0. Now you can use this to plot the vertex of a parabola if you want to: it sits at (-8, -55)

We are decreasing so, we first of find 68% of 225
= 68 / 100 * 225 = 17/ 25 * 225 That is using 4 into 68 and 100
17/5 * 45 Using 5 into 25 and 225.
17 * 9 = 153.
Since we are decreasing then we are going to subtract this result from 225.
If we were increasing we would have added.
= 225 - 153 = 72.
That's our answer. Cheeers.
