Answer:
y = 50x+25
f(x) = 50x+25
Step-by-step explanation:
Using the slope intercept form of the equation, y = mx+b
where x is the amount per day and b is the flat fee
2 days
125 = 2x+b
5 days
275 = 5x+b
Subtract
275 = 4x+b
125 = 2x+b
---------------------
150 = 3x
Divide by 3
150/3 = 3x/3
50 =x
The cost per day is 50 dollars
y = 50x +b
Using the data for 2 days
125 = 50*2 +b
125 = 100 +b
125-100 = b
b = 25
The equation is y = 50x+25
f(x) = 50x+25
To graph, The x axis is number of days and the y axis is total cost
The number of days starts with 0, which is the y intercept
Let x = 0, y =25
Using the slope, we go 50 up and 1 to the right ( 50 dollars per day)
The next point plotted ins ( 1,50)

Answer:
Dave worked 60 hours.
Step-by-step explanation:
Let's assume that Dave worked a total of 
hours.
Since Kate worked 5 hours less than Dave: 
And Sarah worked 10 more hours than Dave: 
Combined, the three siblings worked 185 hours.
Dave worked 60 hours,
Kate worked 55 hours and Sarah worked 70 hours.
To check:
55 + 60 + 70 = 185 hours
Answer:
0.084
Step-by-step explanation:
Since 1,000 has three zeros, move the decimal from 84 three places to the left because when dividing, you need to move the decimal to the left.
84. → .084
So, the answer is 0.084
Hope this helps! :)
