Morton needs to have his car repaired. The auto repair shop charges a fixed dollar amount for labor, plus another dollar amount
1 answer:
The y-intercept of the function is $50 and it represents the fixed amount for the labor charges.
<h3>How to find the y-intercept of a graph?</h3>
From the attached graph, we see that the x-axis is represented by time in hours while the y-axis is represented by labor charges in dollars.
Now, from the graph we see that the coordinates are;
(0, 50), (1, 125), (2, 200), (3, 275), (4, 350)
Now, the y-intercept of a linear graph is simply the point at which the graph crosses the y-axis.
In this graph attached, we see that the y-intercept is at the coordinate (0, (0, 50).
Thus, we conclude that the y-intercept of the function is $50 and it represents the fixed amount for the labour charges.

Answer:
Her average speed is 48 miles per hour.
Step-by-step explanation:
We solve this question using a system of equations.
The speed equation is:
In which s is the speed, d is the distance, and t is the time.
Gabriella drives her car 320 miles and averages a certain speed.
So
Then
If the average speed has been 6 miles less she could have traveled only 280 miles in the same length of time.
So, which s - 6, d = 280.
From the first equation:
Replacing:
Her average speed is 48 miles per hour.
