Find the value of x.A.5B. 40C. 45 D. 20

Answer:
B. 40
Step-by-step explanation:
This is a straight angle; this means that 20 and 4x are supplementary angles.
<u>SUPPLEMENTARY ANGLES:</u> TWO ANGLES WITH A SUM OF 180°.
First, subtract 20 from 180 and from 20.
(cancels itself out).
Now we are left with 4x = 160.
Lastly, divide 160 from 4.
Therefore, the value of x is 40.
Here's an attachment to make this process easier to understand.

<h3>Answer: 2</h3>
Explanation:
The range is y ≤ 2 which means that y = 2 is the largest y can get. The parabola opens downward to form a sort of "frowny face" so to speak. When moving down the parabola, we'll cross the x axis at two different spots. An example of this is shown below with the equation y = -x^2+2.
There's no connection between the '2' in y ≤ 2 and the final answer of 2 roots. We could easily have a range of something like y ≤ 5 or y ≤ 8 and the answer will still remain as 2. The most roots a parabola can have is 2.
