Part A: Sam rented a boat at $225 for 2 days. If he rents the same boat for 5 days, he has to pay a total rent of $480. Write an equation in the standard form to represent the total rent (y) that Sam has to pay for renting the boat for x days.
Part B: Write the equation obtained in Part A using function notation.
Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals.
Answers
(480-225)/(5-2) = 85
Then find b.
225 = 85*2 + b
225 = 170 + b
55 = b
y = 85x + 55 OR f(x) = 85x + 55 This is the answer to PART B.
Standard form PART A is 85x - y = 55
PART C Plot the y intercept, 55. From the y intercept count the slope 85 up right 1 and plot a point, draw a line through the points
The x axis is the number of days so it would be in intervals of 1.
The y axis is money, I would do intervals of $5

Answers
Answer:
20
Step-by-step explanation:
b = a^2/4 +4
Let a =8
b = 8^2 /4 +4
= 64/4 +4
= 16 +4
= 20
Answer:
b = 20 when a = 8.
Step-by-step explanation:
For this problem, we will simply plug the value of a=8 into the given equation for b, to find the value of b.
b = [ (a)^2 / 4 ] + 4
b = [ (8)^2 / 4 ] + 4
b = [ 64 / 4 ] + 4
b = [ 16 ] + 4
b = 20
Hence, when the value of a=8, then the value of b=20.
Cheers.

hope it helped you:)
Answer:
27
Step-by-step explanation:
We are given that a = -5 and y = 7 and we are asked to evaluate the expression -4a + y.
To evaluate the expression, we would plug -5 for a and 7 for y into the expression.
-4a + y = -4(-5) + 7 = 20 + 7 = 27
So -4a + y = 27.
