Let x equal the number of months
Total cost=$30 + $50x
X=5 months
So total cost= 30+50(5)=$280
9514 1404 393
Answer:
Step-by-step explanation:
For values of x less than zero, the graph of the function is a graph of the line
y = -x
Because the function is defined by this expression at x=0, there will be a solid dot at the end of the line there, at (0, 0).
__
For values of x greater than 0, the graph of the function is a graph of the line
y = -x -2
This line has the same -1 slope as before, but has a y-intercept of -2. The function is not actually defined as (0, -2), so there is an open circle at the end of the line there.
-4.5 rose 9.7 then fell 4.8
-4.5 + 9.7 = 5.2
5.2 - 4.8 = 0.4
If it's 4lbs AND 6 oz of clay,
Then she should have 7 oz of clay in each part because 4lbs and 6oz of clay is 70oz of clay and 70/10=7
In this case, the x-axis represents the number of rooms while the y-axis represents the cost of "x" number of rooms. Because the initial house visit fee has not yet included any rooms, we should be looking at x = 0 (also known as the y-intercept). The graph intercepts the y-axis halfway between 20 and 40.
Therefore, the initial house visit fee is $30
I hope this helps!
