Answer:
11. (-4, -1)
12. (2, 7)
Step-by-step explanation:
The midpoint is the average of the end point coordinates. For segment AB, the midpoint M is ...
M = (A+B)/2
If you have A and M, you can find the other end point B from ...
2M = A+B . . . . multiply the above equation by 2
B = 2M -A . . . . subtract A from both sides
__
11. The midpoint (M) is ...
M = ((-1, 2) +(-7, -4))/2 = (-1-7, 2-4)/2 = (-8, -2)/2
M = (-4, -1)
__
12. The missing end point is ...
Z = 2Y -X
Z = 2(-4, 8) -(-10, 9) = (2(-4)+10, 2(8) -9)
Z = (2, 7)

9. To fill up his fuel tank, Sam puts in 16.8 gallons of gas at $3.90 per gallon. How much does Sam spend on fuel? Round to the hundredths place.
Answer:
$65.52
Step-by-step explanation:
y = mx + b
y = amount spent on fuel = ?
m = price per gallon = $3.90
x = gallons = 16.8
b is not needed for this problem
y = (3.90)(16.8)
y = $65.52
The amount of money that Sam spends on fuel will be $65.52.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
To fill up his fuel tank, Sam puts in 16.8 gallons of gas at $3.90 per gallon.
The amount of money that Sam spends on fuel will be given by the multiplication of the numbers 16.8 and 3.9.
⇒ $3.90 x 16.8
⇒ $65.52
The amount of money that Sam spends on fuel will be $65.52.

Write an equation of the line passing through the given points.
(3,-25) and (-3,5)
y=
Answer:
y = -5x -10
Step-by-step explanation:
This is the slope-intercept form:
[tex]y-y_{1} = m(x -x_{1})[/tex]
First, we look for the slope. The slope is found by using the equation:
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1}}[/tex]
[tex]m = \frac{5 - (-25)}{-3 - 3} = \frac{30}{-6} = -5[/tex]
m = -5.
Now, given the two points, our y₁ is -25, and our x₁ is 3. Therefore, we substitute these values into the equation, and get:
y - (-25) = -5(x - 3)
y + 25 = -5(x - 3)
y + 25 = -5x + 15
y = -5x + 15 -25
y = -5x -10
Answer:
the answer to the problem is y= -5x - 10

Lincoln purchased a new car in 2010 for $22,800. The value of the car was $14,100 in the year 2012, then what would be the predicted value of the car in the year 2014, to the nearest dollar?
Answer:
872
Step-by-step explanation:
The predicted value of $16,348 for the car in 2014.
What is the depreciation rate?The depreciation rate is the percentage rate at which an asset is depreciated over its projected useful life.
Given,
The car was purchased for $22,800 in 2010.
The value of the car was $14,100 in 2012.
The time elapsed between 2010 and 2012 is 2 years, so we can calculate the annual depreciation rate as follows:
depreciation rate = (purchase price - value after 2 years) / (purchase price x 2 years)
= (22,800 - 14,100) / (22,800 * 2)
= 0.0798 or 7.98%
This means that the car depreciates by approximately 7.98% of its value per year. To predict the value of the car in 2014, we can use this rate to calculate the value after 4 years (since 2010):
value after 4 years = purchase price x (1 - depreciation rate)⁴
= 22,800 x (1 - 0.0798)⁴
≈ 16,347.97
Rounding this to the nearest dollar gives us a predicted value of $16,348 for the car in 2014.
