Point (-12 , 8) is on the line that passes through (0, 6) and is parallel to the given line ⇒ 1st
Step-by-step explanation:
Parallel lines have:
Same slopesDifferent y-interceptsThe formula of the slope of a line which passes through points [tex](x_{1},y_{1})[/tex] and [tex](x_{1},y_{1})[/tex] is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
∵ The given line passes through points (-12 , -2) and (0 , -4)
∴ [tex]x_{1}[/tex] = -12 , [tex]x_{2}[/tex] = 0
∴ [tex]y_{1}[/tex] = -2 , [tex]y_{2}[/tex] = -4
- Use the formula of the slope above to find the slope of the given line
∵ [tex]m=\frac{-4-(-2)}{0-(-12)}=\frac{-4+2}{12}=\frac{-2}{12}=\frac{-1}{6}[/tex]
∴ The slope of the given line is [tex]\frac{-1}{6}[/tex]
∵ The two lines are parallel
∴ Their slopes are equal
∴ The slope of the parallel line = [tex]\frac{-1}{6}[/tex]
∵ The parallel line passes through point (0 , 6)
- The form of the linear equation is y = mx + b, where m is the slope
and b is the y-intercept (y when x = 0)
∵ m = [tex]\frac{-1}{6}[/tex] and b = 6
∴ The equation of the parallel line is y = [tex]\frac{-1}{6}[/tex] x + 6
Let us check which point is on the line by substitute the x in the equation by the x-coordinate of each point to find y, if y is equal the y-coordinate of the point, then the point is on the line
Point (-12 , 8)
∵ x = -12 and y = 8
∵ y = [tex]\frac{-1}{6}[/tex] (-12) + 6
∴ y = 2 + 6 = 8
- The value of y is equal the y-coordinate of the point
∴ Point (-12 , 8) is on the line
Point (-12 , 8) is on the line that passes through (0, 6) and is parallel to the given line

The point on the line that passes through (0, 6) and is parallel to the given line is (2, 8).
To find a point on a line parallel to the given line, we can use the slope of the given line, which is equal to the slope of the parallel line.
The slope of the given line can be calculated using the coordinates (-12, -2) and (0, -4):
Slope (m) = (change in y) / (change in x) = (-4 - (-2)) / (0 - (-12)) = (-2) / (12) = -1/6.
Now that we know the slope of the parallel line is -1/6, we can use the point-slope form of a linear equation to find the equation of the parallel line:
y - y1 = m(x - x1),
where (x1, y1) is the point (0, 6) and m is the slope (-1/6). Plugging in these values:
y - 6 = (-1/6)(x - 0),
y - 6 = (-1/6)x,
y = (-1/6)x + 6.
Now, we can choose any x-value to find the corresponding y-value. If we plug in x = 2 into the equation, we get:
y = (-1/6)(2) + 6 = -1/3 + 6 = 8.
So, the point (2, 8) is on the line that passes through (0, 6) and is parallel to the given line.

An inscribed triangle with the hypotenuse being the diameter of the circle has angle A be 42 degrees. Angle C is 90 degrees. The area of the triangle ACK is 50cm^2. Find the radius of the circle
Answer:
The Radius of circle is 7.15 cm
Step-by-step explanation:
Given as :
A Triangle is inscribed into circle
The center of circle is O
The Diameter of circle = AK = d
The hypotenuse of triangle being the diameter of circle
The Area of triangle = 50 cm²
Let The radius of circle = r cm
The Triangle is right angle at c
So , ∠ACK = 90°
∠CAK = 42°
∠AKC = 180° - (90° + 42°)
So, ∠AKC = 48°
Now, ∵ Area of triangle ACK = 50 cm²
So, [tex]\dfrac{1}{2}[/tex] × AC × CK = 50
Or, AC × CK = 50 × 2
i.e , AC × CK = 100 ..........1
From figure
Sin 48° = [tex]\dfrac{AC}{AK}[/tex]
Or, 0.74 = [tex]\dfrac{AC}{d}[/tex]
∴ AC = 0.74 d ..........2
Similarly
Sin 42° = [tex]\dfrac{CK}{AK}[/tex]
Or, 0.66 = [tex]\dfrac{CK}{d}[/tex]
∴ CK = 0.66 d .............3
Putting eq 2 and 3 value into eq 1
i.e AC × CK = 100
Or, 0.74 d × 0.66 d = 100
Or, 0.4884 × d² = 100
∴ d² = [tex]\dfrac{100}{0.4884}[/tex]
Or, d² = 204.75
Or, d = [tex]\sqrt{204.75}[/tex]
Or, d = 14.30
So, The diameter of circle = d = 14.30 cm
Now, Radius of circle = [tex]\dfrac{\textrm diameter}{2}[/tex]
Or, r = [tex]\dfrac{\textrm 14.30 cm}{2}[/tex]
i.e r = 7.15 cm
So, The Radius of circle = r = 7.15 cm
Hence, The Radius of circle is 7.15 cm Answer

A circle has a radius with endpoints at(2,5) and (-1,-4).Find the circumference and area of the circle.
Answer:
circumference is 59.6075
area is 282.743
Step-by-step explanation:
To find the circumference and area of the circle, we need to first find the radius. This can be achieved using the distance formula.
The distance formula goes as follows: for any two points on an coordinate plane, the distance can be calculated using a certain method. This method is the derived from the Pythagorean Theorem. Basically, you find the distance from right to left and square it, and then find the distance from up to down and square it. You add these two values together and then square root the whole thing. I know, its complicated.
To apply this to your problem, we do 2-(-1) to find the distance from right to left (x-distance) and then we do 5-(-4) to find the distance from up to down (y-distance). 2-(-1)=3 and squaring that we get 9. 5-(-4)=9 and squaring that we get 81. Adding these two values together, we get 90 and square rooting it we get [tex]\sqrt{90}[/tex].
The formula for circumference of a circle is 2Pi * radius and plugging in our values we get 2Pi * [tex]\sqrt{90}[/tex] which gives us approximately 59.6075.
The formula for area of a circle is Pi * radius^2 and plugging in our values we get Pi * [tex]\sqrt{90}[/tex] ^2 which gives us approximately 282.743.

If 3 hippos eat 5 pumpkins , how many pumpkins per hippo is that ?
Let's solve this problem step by step.
1. We are given the total number of hippos, which is 3.
2. We are also given the total number of pumpkins, which is 5.
3. We want to find out how many pumpkins each hippo gets if the pumpkins are distributed evenly among the hippos.
To find out the number of pumpkins per hippo, we divide the total number of pumpkins by the total number of hippos.
4. Performing the division, we have:
\( \frac{5 \, \text{pumpkins}}{3 \, \text{hippos}} = 1.666... \)
5. Each hippo gets approximately 1.666... pumpkins.
To express the number with a finite number of decimal places, we can round it to the desired precision. For example, rounding to two decimal places, we get 1.67 pumpkins per hippo. This is a simplification, as the fraction actually represents a repeating decimal with the digit 6 repeating indefinitely (i.e., 1.\(\overline{6}\) pumpkins per hippo).

Answer:
The measure of arc AC is [tex]136^o[/tex]
Step-by-step explanation:
Notice that angle BAC (whose measure is given as 34 degrees) is an inscribed angle, and according toe the inscribed angle theorem, the measure of an inscribed angle is half the measure of the central angle that subtends the same chord.
Then, the central angle that subtends the cord BC, is twice 34 degrees ([tex]2\,*\,34^o = 68^o[/tex])
Then, since they give us also the measure of the arc AB which is [tex]156^o[/tex], then the measure of arc AC can be estimated as the needed measure to complete [tex]360^o[/tex] as the sum of all three arcs. That is:
[tex]AC + AB+ BC = 360^o\\AC + 156^o+2\,*\,34^o = 360^o\\AC + 156^o+68^o = 360^o\\AC=360^o-156^o-68^o\\AC=136^o[/tex]

The house would be approximately 10.91 inches tall on the blueprint to represent a 20-foot actual height.
The student asked how many inches high a house would be on a blueprint if the actual home is to be 20 feet tall, and a blueprint states that a 6-inch line represents 11 feet on the actual home. To solve this, we set up a proportion to determine the blueprint's height. The proportion is 6 inches/11 feet = x inches/20 feet, where x represents the height on the blueprint. First, write the proportion as 6 inches/11 feet = x inches/20 feet. Then, cross-multiply to get 11 feet * x inches = 6 inches * 20 feet. To find x, divide both sides of the equation by 11 feet, getting x = (6 inches * 20 feet) / 11 feet. After calculating, we find that x ≈ 10.91 inches. Therefore, on the blueprint, the house would be approximately 10.91 inches tall to represent an actual height of 20 feet.

Therefore Option E) is correct
If n is an odd number then 2(n+1) represents an even number.
Each hotdog cost $1.50 and sodas cost $.50. At the end of the day you made a total of $78.50.You sold a total of 87 hot dogs and sodas combined.How many hotdogs and sodas were sold?
Answer:
35 hotdogs and 52 sodas were sold.
Step-by-step explanation:
Create equations to represent the problem.
let "d" be the number of hotdogs sold
let "a" be the number of sodas sold
1.5d + 0.5a = 78.50 Equation for money made
d + a = 87 Equation for items sold
Rearrange d + a = 87 to isolate one of the variables.
a = 87 - d
Substitute a for 87-d into the other equation. Isolate using reverse operations.
1.5d + 0.5a = 78.50
1.5d + 0.5(87 - d) = 78.50 Distribute over brackets by multiplying
1.5d + 43.5 - 0.5d = 78.50 Collect like terms
43.5 + d = 78.50 1.5d - 0.5d is 1d. You don't need to write "1".
43.5 + d - 43.5 = 78.50 - 43.5 Isolate d, subtract 43.5 from both sides
d = 35 Number of hotdogs sold
Substitute d for 35 in the simpler equation
d + a = 87
35 + a = 87 Subtract 35 form both sides to isolate "a".
a = 87 - 35
a = 52 Number of sodas sold
Therefore 35 hotdogs and 52 sodas were sold.

A custodian plans to repaint some classrooms. He has 5 = gallons of paint. All of
the bookcases are the same size and each requires 2 gallons of paint. How many
bookcases will he be able to repaint with that amount of paint? Show your work...
Answer: 2 bookcases.
Step-by-step explanation:
Let be "x" the number of bookcases that the custodian will be able to repaint completly with 5 gallons of paint.
According to the data given, the custodian needs 2 gallons of paint to repaint one bookcase. Since all the bookcases are equal, you can set up the following proportion:
[tex]\frac{2}{1}=\frac{5}{x}[/tex]
Now you must solve for "x" in order to find its value:
[tex](x)(\frac{2}{1})=5\\\\2x=5\\\\x=\frac{5}{2}\\\\x=2.5[/tex]
Notice that the custodian will be able to repaint 2 bookcases completely, then you can say that:
[tex]x\approx2[/tex]
The custodian will be able to repaint 2 bookcases with 5 gallons of paint.
Explanation:To determine the number of bookcases the custodian will be able to repaint with 5 gallons of paint, we need to divide the total amount of paint by the amount of paint required for each bookcase. Each bookcase requires 2 gallons of paint, so we divide 5 gallons by 2 gallons per bookcase:
5 gallons ÷ 2 gallons/bookcase = 2.5 bookcases

a salesperson at a car dealership earns a monthly salary of $2400 and $250 for each vehicle sold. a. how many vehicles does the salesperson need to sell in a month to earn $4400?
Answer:
8 vehicle.
Step-by-step explanation:
Given: Monthly salary of salesperson is $2400
Incentive of salesperson is $250 per vehicle sold.
First, lets compute income to earned apart from salary.
∴ Deduct salary from the target amount
[tex]\$ 4400-\$ 2400= \$ 2000[/tex]
∴ $2000 need to be earned only through incentive, which is $250 per vehicle sold.
Now, solving to get number vehicles to be sold to earn $2000 as incentive.
Number of vehicle= [tex]\frac{2000}{250}= 8\ vehicles[/tex]
∴ 8 vehicles need to be sold by salesperson to get total earning as $4400.
The salesperson needs to sell 8 vehicles to earn a total of $4400 in a month.
To determine the number of vehicles a salesperson needs to sell to earn a total of $4400, we can set up an equation based on the information provided.
The salesperson earns a fixed monthly salary of $2400 and an additional $250 for each vehicle sold. Let's denote the number of vehicles sold as x
We want the total earnings E to be $4400, so we set up the equation:
4400 = 2400 + 250x
Now, we solve for x
250x = 4400 - 2400
x= 8
Therefore, the salesperson needs to sell 8 vehicles to earn a total of $4400 in a month.
What is the solution to this system of equation?
x=2y-4
7x+5y= -66
Answer:
x=-8 y=-2
Step-by-step explanation:
substitute x for 2y-4
7(2y-4)+5y=-66
factor
14y-28+5y=-66
add 28 on both sides
14y+5y=-38
19y=-38
divide by 19 on both sides
y=-(38/19)
y=-2
Plug -2 into the first equation for y
x=2(-2)-4
x=-4-4
x=-8
