Hello from MrBillDoesMath!
Answer: Only the top left relation is a function.
Discussion:
In the other 3 relations, a vertical line drawn through their graphs intersects the graph in more than 1 point (meaning they aren't functions)

The triangle NET is an <em>isosceles</em> triangle as <u>ET</u> ≅ <u>TN</u> and ET = TN < EN given the condition that BEST is a <em>cyclic</em> quadrilateral.
<h3>How to determine the existence of an isosceles triangle</h3>
In this question we must apply <em>geometric</em> properties of angles and triangles to determine that the triangle NET is an <em>isosceles</em> triangle. <em>Isosceles</em> triangles are triangles with two sides of equal length. In addition, we must apply the geometric concept of proportionality.
Now we proceed to prove the existence of the isosceles triangle:
- <u>BE</u> ≅ <u>SN</u> Given
- ET is the bisector of ∠BES Given
- ET/ES = ET/EB Definition of proportionality
- ES = EB (3)
- <u>ES</u> ≅ <u>EB</u> Definition of congruence
- <u>ET</u> ≅ <u>TN</u> SSS Theorem/Result
Therefore, the triangle NET is an <em>isosceles</em> triangle as <u>ET</u> ≅ <u>TN</u> and ET = TN < EN given the condition that BEST is a <em>cyclic</em> quadrilateral.

To solve for x, the first thing to do is to distribute the 4 to (x-2). When you do this, you should get 4x-8=4x+10
Then, subtract 4x from both sides and then you are left with -8=10. Because -8 is not equal to 10, meaning the equation you are left with is not a true statement, the answer to this would be that there are no real solutions.
divide 42 cm. by 5 minutes, which leaves you with 8.4 cm/minute. hope this helps, please mark brainliest and have a great day
