Mel works as a delivery person for Amazon. The graph shows a linear model for his delivery times on
different days.
(a) What is the equation of the line, first written in point-slope form and then written in slope-intercept
form? Show how you determined the equation.
(b) Based on the linear model, predict how long it initially took Phillip to deliver his packages.
Approximately how much did his delivery time decrease per day?
Answer:
Step-by-step explanation:
Equation of a line passing through (h, k) in point slope form is given by,
y - k = m(x - h)
From the graph attached,
Slope of the line passing through (6, 12) and (3, 21),
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{21-12}{3-6}[/tex]
= -3
Therefore, point - slope form of the line passing through (3, 21) will be,
y - 21 = -3(x - 3)
Now convert this equation in slope intercept form,
y = -3x + 9 + 21
y = -3x + 31
(b). For x = 1 Or day 1
y = -3(1) + 31
y = 28 minutes
Therefore, Phillip took 28 minutes initially to deliver his packages.
Slope of the line states the decrease in the delivery time per day that is 3 minutes per day.
Pam read 126 pages of her summer reading bookin 3 hours. Zac read a180 pages of his summer reading book in 4 hours. If they continue to read at the same speeds, will they both finish the 215 page book after 5 total hours of reading?
Answer:
Zac will finish, Pam won’t
Step-by-step explanation:
Let’s have the individual reading speeds
The individual reading speeds are the number of pages divided by hours taken
For Pam; 126/3 = 42 pages per hour
For Zac; 180/4 = 45 pages per hour
In five hours, Zac would read; 45 * 5 = 225 pages
In five hours, Pam would read 42 * 5 = 210 pages

0.205 (rounded)
Step-by-step explanation:
Perform long division by multiplying the numbers by 1000 to remove the decimals and then solving. Or you could have just used a calculator lol. So I did like 5 digits of it, and you could just round to 0.205, I wouldn't go too far with the decimals even though it is a terminating decimal I believe.

The time of a race is 13.7seconds rounded to 1 decimal place.If the time was x seconds find the inequality in x
Answer:
13.65 ≤ x < 13.75
Step-by-step explanation:
Let x represent the time in seconds. Since the time is 13.7 seconds when rounded to 1 decimal place, hence for this to be possible the minimum value of x is given as x ≥ 13.65 because 13.65 rounded to 1 decimal place is 13.7 seconds. Also, the maximum value of x is given as 13.75 because 13.75 rounded to 1 decimal place is 13.8 seconds.
Therefore the inequality to represent x is:
13.65 ≤ x < 13.75
A farmer is selling apples from his orchard. He uses the equation c = 1.6pto calculate the total cost, c, for every pound of apples, p.
a.) How much does a customer pay for 1 pound of apples?
b.) How much would 8.5 pounds of apples cost?
c.) A customer spent $5.20. How many pounds of apples did they purchase?
Answer:
A) $1.60
B) $13.60
C) 3 1/4 lb
Step-by-step explanation:
What we know:
A farmer uses the equation c = 1.6p to calculate the total cost, c, for p pounds of apples.
A) 1 pound would cost $1.60, as that is the unit rate.
B) 8.5 * 1.6
8.5 + (0.6 * 8.5)
8.5 + 5.1 = $13.60 for 8 1/2 lbs of apples.
C) 5.2/1.6
52/16
13/4 = 3 1/4 lbs of apple for $5.20

What is the average rate of change of f(x) = 5x – 7 from x = -3 to x = 7?
Answer:
[tex]f(x) = 5x - 7 \\ change = f(7) - f( - 3) \\ = ((5)(7) - 7) - ((5)( - 3) - 7) \\ = (35 - 7) - ( - 15 - 7) \\ = (28) - ( - 22) \\ = 50 \\ average \: change = \frac{change}{2} \\ = \frac{50}{2} \\ = 25[/tex]
The rate of change of function f(x) = 5x - 7 from x = -3 to x = 7 will be equal to 5.
A function f(x) = 5x - 7 is given which changes from x = -3 to x = 7.
We have to find out the average rate of change for the given function.
What is the average rate of change of function from [tex]x_{1}[/tex] to [tex]x_{2}[/tex] ?
The average rate of change of function from [tex]x_{1}[/tex] to [tex]x_{2}[/tex] can be given by a formula which is [tex]\frac{f(x_{1})-f(x_{2})}{x_{1} - x_{2}}[/tex].
As per the question ;
The function is f(x) = 5x - 7
So,
At x = -3
f(x) = 5 × -3 - 7
f(x) = -15 - 7
f(x) = -22
At x = 7
f(x) = 5 × 7 - 7
f(x) = 35 - 7
f(x) = 28
Let's use the formula to find average rate of change of function ;
i.e.,
= [tex]\frac{f(x_{1})-f(x_{2})}{x_{1} - x_{2}}[/tex]
= [tex]\frac{(28)-(-22)}{7-(-3)}[/tex]
= [tex]\frac{28+22}{7+3}[/tex]
= [tex]\frac{50}{10}[/tex]
= 5
Thus , the rate of change of function f(x) = 5x - 7 from x = -3 to x = 7 will be equal to 5.

Jada has a meal in a restaurant. She adds up the prices listed on the menu for everything they ordered and gets a subtotal of $42.00.
c) They actually pay $52.99. The additional $7 is a tip for the server. What percentage of the subtotal is the tip?
Answer: See explanation
Step-by-step explanation:
Your question wasn't well written but I saw an identical question so let me help out.
a. Jada has a meal in a restaurant she adds up the prices listed on the menu for everything they ordered and gets a subtotal of $42.00. When the check comes, it says they also need to pay $3.99 in sales tax. what percentage of the subtotal is the sales tax?
b. They actually pay $52.99. The additional $7 is a tip for the server. What percentage of the subtotal is the tip?
a. Subtotal = $42.00
Tax = $3.99
Percentage of subtotal that is sales tax will be:
= Sales tax/Subtotal × 100
= 3.99/42.00 × 100
= 9.5%
b. Tip = $7
Sub total = $42
The percentage of the subtotal that is the tip will be:
= Tip/Sub total × 100
= 7/42 × 100
= 16.67%

As an estimation we are told 5 miles is 8 km.
Convert 17.6 km to miles.
Answer:
17.6 kilometers are equal to 11 miles.
Step-by-step explanation:
Given that:
8 kilometers = 5 miles
Unit rate in terms of kilometer.
1 kilometer = 5/8 miles
Now,
We have to convert 17.6 kilometers in miles
17.6 kilometers = [tex]\frac{5}{8}*17.6[/tex]
17.6 kilometers = [tex]\frac{5}{8}*\frac{176}{10}[/tex]
17.6 kilometers = 11 miles
Hence,
17.6 kilometers are equal to 11 miles.
