12(0.57)= 6.84
10-6.84= 3.16
Mr. Turner’s change is $3.16.
Hope this helps!
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
Well, we can find the answer by multiplying the two fractions. 3/4*1/8 equals 3/32.
2,000 + 400 + 70 would equal 2,470.
The correct way to write it would be 2,000 + 400 + 7
