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.
Answer:
three times
Step-by-step explanation:
Hi there! The answer is 17 + 3x
We can only add up 9 and 8, so we get 9 + 8 = 17. Next we need to add the 3x to the sum, hence: 17 + 3x.
Answer:
1) 2
2) 3
3) y = 2x + 3
