Answer: 30 degrees
Step-by-step explanation:
You can use the vertical line test to determine if the graph is a function.
A function must: for every x value have only one y value.
Vertical line test: if you draw a bunch of vertical lines each line only touches the graph once.
So a circle would not be a function, or a horizontally facing parabola, etc... Remember, if you draw a vertical line "|" and it touches the graph more than once at any point then it is not a function.
Now take a look at the graph in the question.
In this graph if we do the vertical line test there are no place where a vertical line touches the graph twice so this graph is indeed a function.
This means your answer is C. Yes

Step-by-step explanation:
30% of the pie chart is pizza. 30% of 80 = 0.3 * 80 = 24
Answer:
(4,1)
Step-by-step explanation:
when points are reflected on the y-axis you switch your x coordinate from positive to negative or the other way around the y coordinate stays the same.
(2,1) reflected is (-2,1)
(7,4) reflected is (-7,4)
(-8,-4) reflected is (8,-4)
so (-4,1) reflected is (4,1)
