Answer:
-586
Step-by-step explanation:
Add 538 to both sides
p-538+538=-1124+538=
p=-1124-538
=-586
Consider all parabolas:
1.

When x=-3, y=-1, then the point (-3,-1) is vertex of this first parabola.
2.

When x=-4, y=-4, then the point (-4,-4) is vertex of this second parabola.
3.

When x=2.5, y=20.25, then the point (2.5,20.25) is vertex of this third parabola.
4.

When x=3.5, y=19.25, then the point (3.5,19.25) is vertex of this fourth parabola.
5.

When x=-1.75, y=-1.125, then the point (-1.75,-1.125) is vertex of this fifth parabola.
6.

When x=2, y=13, then the point (2,13) is vertex of this sixth parabola.
Answer:
B. (3x - 12)° = (2x + 8)°
Step-by-step explanation:
This equation can be used to solve x.
3x - 12 = 2x + 8
3x - 2x = 12 + 8
x = 20°
-------------------------------------------------------------------
Verification:
3(20) - 12 = 2(20) + 8
60 - 12 = 40 + 8
48° = 48°
Answer:
D
Step-by-step explanation:
A function is where each input (here, the input is x) corresponds to exactly one output (here, the output is y). In other words, if a function is graphed, we should be able to draw a vertical line through every single part of it that will intersect it at only one place.
Let's examine each choice.
(A) Well, if we draw a vertical line through the graph, it will obviously intersect the entire line - which is an infinite number of intersections, so this is not a function.
(B) If we draw a vertical line through the portion of the graph that lies near the positive x-axis, we note that it will intersect twice, so this is not a function.
(C) If we strategically draw a vertical line through the y-axis, we see it will intersect two times, so this is not a function.
(D) We can draw a vertical line through any portion of this graph and know that it will only intersect once.
Therefore, the answer is D.
