Answer:
I have labeled the arcs AB and CD. The measure of angle x is 60°
Step-by-step explanation:
The measure of angle x is ½(mAB + mCD)
![x = \frac{1}{2} (80 + 40) \\ \frac{120}{2} = 6 \\ x = 60](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%2880%20%2B%2040%29%20%5C%5C%20%20%5Cfrac%7B120%7D%7B2%7D%20%20%3D%206%20%5C%5C%20x%20%3D%2060)
Step One they didn't bring the negative into the answer when dividing - 4(3/2) which would = -6 but in the equation it's a positive so that wouldnt be the answer
Using the function concept, it is found that this sequence is a function because it passes the vertical line test.
A function relates <u>each value of the input to one value of the output</u>, hence, option b is incorrect.
- On a graph, each value of x(horizontal axis) is mapped to a value of y(vertical axis), hence, a vertical line test can be applied to determine whether the relation is a function.
In this problem:
- For each day, there is only one output, which is her balance, hence, it passes the vertical line test.
