Answer:

Step-by-step explanation:
First off, <em>B</em> is zero, so there is no <em>phase shift</em>, meaning that the vertex stays on the y-axis. Next, <em>A</em> is negative, so the parabola opens down, and whenever you have a parabola opening down, it does so at maximum. Finally, <em>C</em> represents our y-intercept, or in this case, our <em>vertical shift</em>. Our y-intercept is (0, −1), and so as our vertex, hence our answer.

Since the triangles are similar, we can use ratios to find what x equals.
Ratios:
3x+8/4 = 25/5
The easiest way to solve ratios, in my opinion is to cross multiply.
3x+8*5 = 4*25. Simplify to get 15x + 40 = 100.
Subtract 40 on both sides. 15x = 60.
Divide 15 on both sides. x = 4.
