(35 + 47 + 42 + x) / 4 = 50
(124 + x) / 4 = 50....multiply both sides by 4, cancelling the 4 on the left side.
124 + x = 50 * 4
124 + x = 200
x = 200 - 124
x = 76 <===
Domain is everything below 0. Range is all real numbers. It is a function as it passes the vertical line test.
Considering the angle of the ray, it is found that the value of x is of x = 55º.
<h3>What is the angle of the ray?</h3>
The ray has an angle of 180º. It is composed by:
Hence:
x + 35 + 90 = 180
x = 180 - 125
x = 55º.

Answer:
-3 and 1
Step-by-step explanation:
The zero(root, range) of a parabola is where the parabola touches the x axis, here you can see that the parabola touches 1 and -3 on the x axis, hence that is the root.
