Answer:
Step-by-step explanation:
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the line PQ passing through the two points P(-8, 2) and Q(4, 2) will be,
Slope '[tex]m_1[/tex]' = [tex]\frac{2-2}{-8-2}[/tex] = 0
Therefore, slope of the line PQ parallel to the x-axis = 0
Slope of the line MN passing through the points M(8, 6) and N(8, -8) is,
Slope '[tex]m_2[/tex]' = [tex]\frac{6+8}{8-8}[/tex] = ∞
Therefore, slope of the line MN parallel to y-axis is undefined.
Since, angle between the x-axis and y-axis is 90°,angle at the intersection point between the lines parallel to x and y axis will be 90°.
These lines are perpendicular to each other.

In this figure, C is the intersection of lines h and i
because C is the point contained by both h and i.
(6,11) and (5,9) on a line in standard form
Answers
Answer:
2x - y = 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (6, 11) and (x₂, y₂ ) = (5, 9)
m = [tex]\frac{9-11}{5-6}[/tex] = [tex]\frac{-2}{-1}[/tex] = 2 , thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (5, 9) , then
9 = 10 + c ⇒ c = 9 - 10 = - 1
y = 2x - 1 ← in slope- intercept form
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
From y = 2x - 1 ( subtract y and add 1 to both sides )
2x - y = 1 ← equation in standard form

Answers
Answer:
B)Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90 clockwise
Step-by-step explanation:
This is because, to locate a point rotated by 90° from point A, we first draw a circle with the origin as its center and a radius of the origin and point A. We then locate a point on the line that is 90° clockwise from point A. For a 90° clockwise rotation, for a given pair of coordinates, (x,y), the resulting pair of coordinates is (y,-x). So, for the coordinates (1,4), the resulting coordinates we are looking for is (4, -1), which is the point rotated 90° clockwise from point A. The point is thus (4,-1).

Step-by-step explanation:Hi there !
5(3x - 1) - 3(5x - 1) =
= 15x - 5 - 15x + 3
= 15x - 15x + 3 - 5
= - 2
Good luck !
The expression 5(3x - 1) - 3(5x - 1) simplifies to -8 after using distributive property and adding like terms.
To expand the brackets and collect like terms in the expression 5(3x - 1) - 3(5x - 1).
Distribute the numbers outside the brackets to the terms inside the brackets:
5(3x - 1) - 3(5x - 1)
= 5×3x - 5 × 1 - 3 × 5x - 3 × 1
Perform the multiplication:
15x - 5 - 15x - 3
Collect like terms (combine the x terms and the constants):
=(15x - 15x) + (-5 - 3)
=0x - 8
Simplify:
-8
So, the expression 5(3x - 1) - 3(5x - 1) simplifies to -8.

There’s a few ways to do this. But you essentially want to find the area for each rectangle and add them together.
We can do the two rectangles on the left, bedroom 1 and 3, by doing 3.5 x (4.25+3.75) = 31.5 in^2
Now do bedroom 2, we have to do 7.5 - 3.5 to get the width of the room since it wasn’t given directly. The width is 4 and we have the length of 3.5. Do 4 x 3.5 to get 14 in^2
31.5 + 14 = 45.5 in^2
We’re not done yet because they want it in ft^2 and we’re given 1 inch = 4 feet
Just do 45.5 x 4 to get 182 ft^2

Answer:
x= 29
Step-by-step explanation:
These angles equal 180° since they are corresponding angles.
So, the equation would be: (2x-10)+(4x+16)= 180.
Step 1- Add common variables.
(2x+4x)+(16-10)= 180
6x+6= 180
Step 2- Subtract 6 to both sides.
6x+6= 180
-6 -6
6x= 174
Step 3- Divide both sides by 6.
6x= 174
6 6
x= 29
Answer:
x=29
Step-by-step explanation: The two angles for are supplementary, so the equation will be equal to 180 degrees. So to find 180 degrees you need to put (2x-10) and (4x+16) on the same side of the equation.
180=(2x-10)+(4x+16) Combine like terms
180=6x+6 Subtract 6 from both sides
174=6x Divide both sides by 6
29=x
Check:
2*29-10
58-10= 48
4*29+16
116+16=132
132+48=180
please explain the steps to me . i’m genuinely confused
Answers
Answer:See below
Step-by-step explanation:
These angles are equal. All that needs to be done is setting the equations as equal and solving for the variables. Once the variables are found, input them back into the equation to find the angles. Once the variables are put into both equations, the result should be equal.
Answer:
13) 94°
14) 105°
Step-by-step explanation:
13) For this equation, the angles are vertical angles. This means that they equal each other. So the equation would be: 14x-4= 12x+10.
Step 1- Subtract 12x to both sides.
14x-4= 12x+10
-12x -12x
Step 2- Add 4 to both sides.
2x-4= 10
+4 +4
Step 3- Divide both sides by 2.
2x= 14
2 2
x= 7
Now that you know the value of the variable, insert this into the equations.
14(7)-4= 98-4= 94°
12(7)+10= 84+10= 94°
14) For this equation, the angles are alternate exterior angles. This also means that they equal each other. So the equation would be: 16x-7= 15x.
Step 1- Add 7 to both sides.
16x-7= 15x
+7 +7
Step 2- Subtract 15x to both sides.
16x= 15x+7
-15x -15x
This leaves you with: x= 7.
Now, insert the value of the variable into the equations.
16(7)-7= 112-7= 105°
15(7)= 105°

A dairy company gets milk from two dairies and then blends the milk to get the desired amount of butterfat. Milk from dairy I costs $2.40 per gallon, and milk from dairy II costs $0.80 per gallon. At most $144 is available for purchasing milk. Dairy I can supply at most 50 gallons averaging 3.9% butterfat, and dairy II can supply at most 90 gallons averaging 2.9% butterfat. Answer parts a and b. a. How much milk from each supplier should the company buy to get at most 100 gallons of milk with the maximum amount of butterfat? The company should buy 40 gallons from dairy I and 60 gallons from dairy II. What is the maximum amount of butterfat? 330 gallons (Type an integer or a decimal.) b.

The excess capacity of dairy I is 10 gallons, and for dairy II it is 30 gallons. Is there any way all this capacity
Answers
Answer:
a) i The company should buy 40 gallons from dairy I and 60 gallons from dairy
ii) What is the maximum amount of butterfat? The total amount of butterfat from Diary I and Diary II = 3.12% + 1.93%
=5.05%
b.The excess capacity of dairy I is 10 gallons, and for dairy II it is 30 gallons.
Step-by-step explanation:
a. How much milk from each supplier should the company buy to get at most 100 gallons of milk with the maximum amount of butterfat?
From the question, we are told that:
Milk from dairy I costs $2.40 per gallon, Milk from dairy II costs $0.80 per gallon.
Let's represent:
Number of gallons of Milk from dairy I = x
Number of gallons of Milk from dairy II = y
At most $144 is available for purchasing milk.
$2.40 × x + $0.80 × y = 144
2.40x + 0.80y = 144........ Equation 1
x + y = 100....... Equation 2
x = 100 - y
2.40(100 - y) + 0.80y = 144
240 - 2.4y + 0.80y = 144
-1.60y = 144 - 240
-1.6y = -96
y = -96/-1.6
y = 60
From Equation 2
x + y = 100....... Equation 2
x + 60 = 100
x = 100 - 60
x = 40
Therefore, since number of gallons of Milk from dairy I = x and number of gallons of Milk from dairy II = y
The company should buy 40 gallons from dairy I and 60 gallons from dairy
II. What is the maximum amount of butterfat?
From the question
Dairy I can supply at most 50 gallons averaging 3.9% butterfat,
50 gallons = 3.9% butterfat
40 gallons =
Cross Multiply
= 40 × 3.9/50
= 3.12%
Dairy II can supply at most 90 gallons averaging 2.9% butterfat.
90 gallons of milk = 2.9% butter fat
60 gallons of milk =
Cross Multiply
= 60 × 2.9%/90
=1.9333333333%
≈ 1.93%
The total amount of butterfat from Diary I and Diary II = 3.12% + 1.93%
=5.05%
b. The solution from part a leaves both dairy I and dairy II with excess capacity. Calculate the amount of additional milk each dairy could produce.
Excess capacity of Diary I =
50 gallons - 40 gallons = 10 gallons
Excess capacity of Diary II =
90 gallons - 60 gallons = 30 gallons
Therefore, the excess capacity of dairy I is 10 gallons, and for dairy II it is 30 gallons.

Given:
Ratio of white shapes to black shapes is 5:11
Ratio of white circles to white squares is 3:7
Ratio of black circles to black squares is 3:8
To find: fraction of all the shapes that are circles
Solution:
As ratio of white shapes to black shapes is 5:11,
let number of white shapes be 5 k and number of black shapes by 11 k
As ratio of white circles to white squares is 3:7,
Number of white circles = [tex]\frac{3}{10}(5k)=\frac{3}{2}k[/tex]
Number of white squares = [tex]\frac{7}{10}(5k)=\frac{7}{2}k[/tex]
As ratio of black circles to black squares is 3:8,
Number of black circles = [tex]\frac{3}{11} (11k)=3k[/tex]
Number of black squares = [tex]\frac{8}{11}(11k)=8k[/tex]
Total number of circles = [tex]\frac{3}{2}k+3k=\frac{9}{2} k[/tex]
Total number of shapes = [tex]5k+11k=16k[/tex]
Therefore,
Fraction of circles [tex]=\frac{\frac{9}{2} k}{16k} =\frac{9}{32}[/tex]
