I would try B.
I'm not positive i got it right
(sorry if its wrong)
Hope this helped!
:)
Answer:
Option A.
and 
Step-by-step explanation:
we know that
The solution of the first inequality is the shaded area below the solid line 
The solid line passes through the points (0,4) and (3,0) (the y and x intercepts)
therefore
The first inequality is

The solution of the second inequality is the shaded area to the right of the solid line x=0
therefore
The second inequality is

<u>Answer</u>:
x = 20
<u>Explanation</u>:
all the interior angles in the triangle is 180°
<u>therefore</u>:
4x - 17° + 71° + 46° = 180°
4x + 100° = 180°
4x = 180° - 100°
4x = 80°
x = 20°
The vertex is (-1, 2).
The equation of parabola:
where (h, k) is the vertex
We have h = -1 and k = 2.
Substitute:


Step-by-step explanation:
Given expression is;

Solving for 
Multiplying both sides by 2

Dividing both sides by h

Subtracting
from both sides
