Answer:
Doug sold 100 sandwiches in his neighborhood.
Step-by-step explanation:
To solve for percentage you have to first find the percentage's decimal. To find this you have to the move the decimal point up to places. This makes 80 into 0.8. After you do this you will mutiply that but the total amount. So 125 times 0.8. Once you do this you should get 100. This means that Doug sold 100 sandwiches in his neighborhood.
Your answer is C hope this helps
Answer:
follow the steps bellow
Step-by-step explanation:
since you already have the x values it is easier,once you have the the y values you are going to plot the point the left side of the table are the x values and the right side are the y values. X values on a graph is the horizontal line or the line that goes left to right, and the y values on the graph re the line that goes vertical or up and down.
70=3x+10
Subtract 10 from both sides
60=3x
Divide both sides by 3
20=x
x=20
Answer:
A. Both functions are positive and decreasing on the interval.
Step-by-step explanation:
The table shows that f(x) decreases when x increases in the interval (0,3).
All the values of f(x) are positive in the interval (0,3).
For the exponential function that passes through the points (0, 27) and (3, 0), we also see that f(x) is decreasing when x increases: when x goes from 0 to 3, f(x) goes from 27 to 0.
Also all the values of f(x) are positive in the interval.
Then, both functions are positive and dereasing in the interval.
