Answer:
x = 0
Step-by-step explanation:
Since the product is not equal zero, we need to multiply both parenthesis first:
Add 27 from both sides:
Factor 
out:
Apply the zero product:
The solutions of the equation are 
and 
.
We can conclude that the correct answer is x = 0.
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)
Draw a straight line
57 because 5(6)+3(7)+6 is 30+21+6=57
If you divide 120 by 150 you will end up getting 0.8 also known as 80%.
