Answer:
A & B
Step-by-step explanation:
See attachment for complete question
Given
[tex]y = \frac{1}{2}x[/tex]
Analyzing the given options
Option A:
[tex]6y = 3x[/tex]
Divide both sides by 6
[tex]\frac{6y}{6} = \frac{3x}{6}[/tex]
[tex]y = \frac{3x}{6}[/tex]
[tex]y = \frac{1}{2}x[/tex]
This is true for the given expression:
Option B:
From the graph:
x = 2, when y = 1
x = 4, when y = 2
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{2 -1}{4 - 2}[/tex]
[tex]m = \frac{1}{2}[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 1 = \frac{1}{2}(x - 2)[/tex]
[tex]y - 1 = \frac{1}{2}x - 1[/tex]
Add 1 to both sides
[tex]y - 1 +1 = \frac{1}{2}x - 1 + 1[/tex]
[tex]y = \frac{1}{2}x[/tex]
This is also true for the given expression.
Option C:
From the graph:
x = 2, when y = 4
x = 4, when y = 8
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{8 - 4}{4 - 2}[/tex]
[tex]m = \frac{4}{2}[/tex]
[tex]m =2[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 4 = 2(x - 2)[/tex]
[tex]y - 4 = 2x - 4[/tex]
Add 4 to both sides
[tex]y - 4 + 4= 2x - 4 + 4[/tex]
[tex]y = 2x[/tex]
This isn't true for the given expression.
Option (D):
From the table:
x = 2, when y = 1
x = 4 when y = 3
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{3 - 1}{4 - 2}[/tex]
[tex]m = \frac{2}{2}[/tex]
[tex]m = 1[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 1 = 1 * (x - 2)[/tex]
[tex]y - 1 = x - 2[/tex]
[tex]y = x - 2 +1[/tex]
[tex]y = x - 1[/tex]
This isn't true for the given expression.

Work Shown:
Everywhere you see an x, replace it with 5.
Then use PEMDAS to simplify.
y = 4*(x-2)*(x-3) + 7*(x-2)*(x-5) - 6*(x-3)*(x-5)
y = 4*(5-2)*(5-3) + 7*(5-2)*(5-5) - 6*(5-3)*(5-5)
y = 4*(3)*(2) + 7*(3)*(0) - 6*(2)*(0)
y = 24 + 0 - 0
y = 24
This means,
4*(x-2)*(x-3) + 7*(x-2)*(x-5) - 6*(x-3)*(x-5) = 24

B.0.8x, individuals signing up the day of the activity get ch arg ed 20% more
C.1.20x, individuals signing up the day of the activity get ch arg ed20% less
D.O.8x, individuals signing up the day of the activity get ch arg ed20%less
Answer:
A. 1.20x; individuals signing up the day of the activity get charged 20% more
Step-by-step explanation:
Amount charged before the day of activity = x
Amount charged on any individual who decides to sign up on the day of activity would be the normal price, x dollars, plus an additional price of 0.20x dollars.
0.20x = 20% of x.
That is, the additional fee added to the normal price is 20% of the normal price.
Therefore, amount paid on the day of the activity is x + 0.20x = 1.20x dollars.
What this fee means is that those who decide to sign up on the day of the activity are charged 20% more.

An engineer is designing three triangular traffic signs with a computer program. The vertices of Sign A are located at (2, 2) , (2, 12) , and (17, 7) . The vertices of Sign B are located at (4,4),(11, 19) and (18, 4) . The vertices of Sign C are located at (4, 8), (24, 1) , and (24, 15) . Put the signs in order from largest to smallest perimeter. Sign A Sign B Sign C
Answer:
sign C, sign B, sign A
Step-by-step explanation:
Given the vertices of triangular post A as (2, 2) , (2, 12) , and (17, 7). Let us find the length of side of the post using the formula for calculating distance between 2 points using the formula:
D = √(y₂-y₁)²+(x₂-x₁)²
For the coordinate (2, 2) , (2, 12)
S₁ = √(12-2)²+(2-2)²
S₁ = √(10)²+(0)²
S₁ = √100
S₁ = 10
For the coordinate (2, 2) , (17, 7)
S₂ = √(7-2)²+(17-2)²
S₂ = √(5)²+(15)²
S₂ = √25+225
S₂ = √250
S₂ = 15.8
For the coordinate (2, 12) , (17, 7)
S₃ = √(7-12)²+(17-2)²
S₃ = √(-5)²+(15)²
S₃ = √25+225
S₃ = √250
S₃ = 15.8
Perimeter of sign A = S₁+S₂+S₃
Perimeter of sign A = 10+15.8+15.8
Perimeter of sign A = 41.6
FOR SIGN B with coordinate of vertices (4,4),(11, 19) and (18, 4)
For the coordinate (4, 4) , (11, 19)
S₁ = √(19-4)²+(11-4)²
S₁ = √(15)²+(7)²
S₁ = √225+49
S₁ = 16.6
For the coordinate (4, 4) , (18, 4)
S₂ = √(4-4)²+(18-4)²
S₂ = √(0)²+(14)²
S₂ = √196
S₂ = 14
For the coordinate (11, 19) , (18, 4)
S₃ = √(4-19)²+(18-11)²
S₃ = √(-15)²+(7)²
S₃ = √225+49
S₃ = 16.6
Perimeter of sign B = S₁+S₂+S₃
Perimeter of sign B = 14+16.6+16.6
Perimeter of sign B = 47.2
FOR SIGN C with coordinate of vertices (4, 8), (24, 1) , and (24, 15)
For the coordinate (4, 8) , (24, 1)
S₁ = √(1-8)²+(24-4)²
S₁ = √(-7)²+(20)²
S₁ = √49+400
S₁ = 21.2
For the coordinate (4, 8) , (24, 15)
S₂ = √(15-8)²+(24-4)²
S₂ = √(7)²+(20)²
S₂ = √49+400
S₂ = 21.2
For the coordinate (24, 1) , (24, 15)
S₃ = √(15-1)²+(24-24)²
S₃ = √(14)²+(0)²
S₃ = √196+0
S₃ = 14
Perimeter of sign C = S₁+S₂+S₃
Perimeter of sign C = 14+21.2+21.2
Perimeter of sign C = 56.4
Arranging in order from largest to smallest perimeter, Sign C(56.4), Sign B (47.2), sign A (41.6)

What is the measure of angle q°?
70°
110°
90°
180°
Answer:
sorry but where are the angles
The value of q in the quadrilateral 70°
Given that a quadrilateral we need to find the value of q,
Since we can see that the opposite angles are equal so the quadrilateral can be a parallelogram,
Therefore, we get, q and 110° is consecutive angles and the consecutive angles in a parallelogram are supplementary angles,
So,
110° + q° = 180°
Solve for q,
q° = 180° - 110°
Simplification
q° = 70°
Hence the value of q is 70.

Answer:
x = 20
Step-by-step explanation:
You're in luck I take H geometry.
What I'm going to do is this. 4x - 18 and 3x + 2 are alternate interior angles so they equal the same, so use this equation.
4x -18 = 3x + 2 (add 18 on both sides)
4x = 3x + 20 (minus 3x on both sides)
x = 20
plug in
4(20) - 18 = 3(20) + 2
80 - 18 = 60 + 2
62 = 62

Answer: 2 inches
Step-by-step explanation:
14 inches
Step-by-step explanation:
Length of the hole = 16(½) inches
Length of the dirt = 8(¾)inches
The distance between the top of the pile to the bottom of the hole = ?
Since the dirt is beside the hole and not inside the hole, we can find it's length using addition.
Distance from the top to the bottom = length of dirt + length of the hole
Length of dirt = 8×¾ = 6 inches
Length of the hole = 16 × ½ = 8 inches
Distance from the top of the dirt to the bottom of the hole = (6 + 8) inches
Distance from the top of the dirt to the bottom of the hole = 14 inches
Note: the only way we can use subtraction here is if the hole was filled with dirt, what's the distance that's left
Distance left = length of hole - length of dirt
Distance left = 8 - 6 = 2 inches .
