Answer:
9) y = -200x + 1200
11) slope = -2
15) $2,450
16) 9 days
Step-by-step explanation:
9) Given the two points from the graph:
Let (x₁, y₁) = (0, 1200)
(x₂, y₂) = (1, 1000)
Substitute these values into the following slope formula:
m = (y₂ - y₁)/(x₂ - x₁)
m = (1000 - 1200)/(1 - 0)
m = -200/1
m = -200
The slope of the line is -200.
Next, we need to determine the y-intercept, which is the point on the graph where it crosses the y-axis. Upon observing the graph, it shows that the line crosses at point (0, 1200). The y-coordinate of this ordered pair is the value of the y-intercept, b = 1200.
Therefore, the linear equation in slope-intercept form is y = -200x + 1200.
11) Given the points, (5, -18) and (-4, 0):Let (x₁, y₁) =(5, -18)
(x₂, y₂) = (-4, 0)
Substitute these values into the following slope formula:
m = (y₂ - y₁)/(x₂ - x₁)
[tex]m = \frac{0 - (-18)}{-4 - 5} = \frac{0 + 18}{-9} = -2[/tex]
Therefore, the slope of the line is -2.
15) Solve:Given the fixed fee of $200, and the $150 per hour after the initial meeting:
We can represent these in slope-intercept form:
y = 150x + 200
y = total cost for the Attorney's services
x = number of hours worked.
The y-intercept in this given problem is $200, which represents the flat fee charged for the initial meeting. While the slope in this equation is $150, which is the hourly rate that an Attorney charges his clients after the initial meeting.
If an Attorney works for 15 hours, then:
Let x = 15, and substitute its value into the equation to find the total cost:
y = 150x + 200
y = 150(15) + 200
y = 2,250 + 200
y = 2,450
Therefore, a client will pay a total of $2,450 for an Attorney's 15 hours of work.
16) Solve:Given the water level on a Lake of 165 inches after a rainstorm, and the water level's receding rate of 3 inches per day:
We can establish the following linear equation to model this given problem:
L = -3d + 165
Where:
L = represents the water level of the Lake
d = number of days that the water level recedes
In order to find the number of days it will take before the water level recedes to 84 inches:
Substitute the value of L = 84 into the equation:
L = -3d + 165
84 = -3d + 165
Subtract 165 from both sides:
84 - 165 = 3d + 165 - 165
-27 = -3d
Divide both sides by -3:
[tex]\frac{-27}{-3} = \frac{-3d}{-3}[/tex]
9 = d
Therefore, it will take 9 days for the water level to be at 84 inches.

For each 16 unit increase in x, you get a 6 unit increase in y.
So, you can approach this with the idea of slope (change in y over change in x) to have a slope of 6/16 or 3/8.
y = 3/8 x

Austin earns $9.75 an hour at a part-time job, and earns $12 each time mowing lawns in the neighborhood. They graph the amount of hours worked at the part-time job (X) and the number of lawns mowed (Y) to determine how to earn more than $300. Which type of boundary line should be used in the graph?HELP!
Answers
Answer:
$7.25 at part-time job
$9.00 every time lawn mowed
so he would get 33.33 day so we will just say 33 times to get 300 dollars if he gets $9 for mowing. And 41.37 hours to get $300 and he would have to use x and y graph to find the boundary line.
Step-by-step explanation:
Linear programming is a mathematical method that is used to determine the best possible outcome or solution from a given set of parameters or list of requirements,
Here, graph is attached in which boundary line is shown to earn more than $300 .
Let us consider that, Austin spend x hours in part time job and y times in mowing lawns.
Since, Austin earns $9.75 an hour at a part-time job,
In x hours, Austin earns = 9.75 x
Since, Austin also earns $12 each time mowing lawns
So, if he mowing lawns y times. he earns = 12y
Total earning = 9.75x + 12y
Since, Austin Austin wants to earn more than $300
Therefore, 9.75x + 12y > 300
Thus, boundary line for above equation shown in attached graph.
