C the third one
Step by step
Answer:
Number of hot dogs sold = 56
Number of hamburgers sold = 52
Step-by-step explanation:
Let
Number of hot dogs sold = x
Number of hamburgers sold = y
We can make equation from given equations:
(Hot dogs were sold for $.50 (fifty cents), and hamburgers were sold for $1 (one dollar). The total money raised by your class was $80. )
(Together you sold 108 hot dogs and hamburgers.)
Now we cam solve these system of equations to find value of x and y

Subtract both equations to get value of x:

We get value of x = 56
Now putting value of x in equation 2 to find value of y

So, we get y = 52
Therefore,
Number of hot dogs sold = x = 56
Number of hamburgers sold = y = 52
The variable a cannot be zero because that would make -9a = zero and 8 divided by zero is indeterminate.
Answer:
f(7) = 6
Step-by-step explanation:
f(7) is the y coordinate of the point on the given graph of y = f(x), whose x coordinate is 7.
From the graph of y = f(x), we see that f(7) = 6.
