Answer:
1 hour and 30 minutes (1.5 hours)
Step-by-step explanation:
$25 per hour is our slope and $25 call fee is our y-intercept.
We can write a linear function in slope-intercept form like this:
Where m is your slope, y is the total cost, x is the hours worked b is your y-intercept. Therefore using the information above we obtain:
Since the bill comes out to be $62.50 that means that y=62.50 by substituting that value we have to solve for x since x is the amount of hours worked we obtain:
Since x = 1.5 this means that the plumber worked for one and a half hours or 1 hour and 30 minutes.
Draw a number line!
<________|_______________|_______|___________>
-5 0 2
The ones on the right are larger than the ones on the left. The two is the rightmost number, so it is the largest. Your inequality reads "-5 is less than 2" which is true. Therefore, you have a true inequality.
Answer:
it may be B.
