Work Shown:
x = preimage length = 12
y = image length = 4
z = scale factor
z = y/x
z = 4/12
z = (1*4)/(3*4)
z = 1/3
The scale factor is 1/3.
This means the image is 1/3 of the length of the preimage.
In order for Josh to graph the solution to the inequality 4x - 2y > 6, which of the following steps does he need to use? Select all that apply.
Shade above the line.
Solve the inequality as y < 2x-3.
Draw the line y=2x-3 as a solid line.
Draw the line y=2x-3 as a dashed line.
Shade below the line.
Solve the inequality as y> 2x-3.
Solve the inequality as y < 2x-3.
Draw the line y=2x-3 as a dashed line.
Shade below the line.
Josh needs to follow the steps to draw the required inequality graph.
Solve the inequality y < 2x - 3 by solving for the x and y-interceptDraw the straight line y < 2x - 3 as a dashed line (since we have less than sign )Shade below the line. (Below the line are shaded for inequality sign that is "less than")Inequality expressions are expressions that are not separated by an equal sign.
Given the inequality expression 4x - 2y > 6,
Dividing through by 2 will give:
4x/2 - 2y/2 > 6/2
2x - y > 3
Make y the subject of the formula
-y > -2x + 3
y < 2x -3
For Josh to plot the inequality graph of y < 2x - 3, he needs to follow the process;
Solve the inequality y < 2x - 3 by solving for the x and y-interceptDraw the straight line y < 2x - 3 as a dashed line (since we have less than sign )Shade below the line. (Below the line are shaded for inequality sign that is "less than")Learn more here: https://brainly.com/question/6874464

A school lunch costs $2.50. A monthly lunch pass costs $40.00. Which inequality represents the number x of lunches you must purchase for the monthly pass to be a better deal?
Answer:
The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.
Step-by-step explanation:
Given that:
Cost of each lunch = $2.50
Cost of monthly lunch pass = $40.00
Number of lunches = x
For making the monthly pass a better deal, the cost of lunches should be greater than the cost of monthly lunches, therefore
Cost of lunch * Number of lunches > Cost of monthly lunch pass
2.50x > 40.00
Hence,
The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.
Answer:
2.50x > 40.00
$2.50 times a number of lunches is greater than $40.

what is the integer of The change in a balloon's volume when it loses 450 cm3 of air.
Answer:
The integer change is -450 cm^3
Step-by-step explanation:
Here, we want to write the integer of the change in the volume of a ballon when it loses 450 cm^3 of air
Losing this volume means we are subtracting 450 from the original volume
This represents a change of -450 cm^3

Sarah is walking diagonally across a park as modeled by the equation y = x − 1. Suppose Marcus starts walking at the point (0, 9) so his path is perpendicular to Sarah's. At what point will Sarah's path and Marcus's path intersect?
Answer:
[tex]A(10,9)[/tex]
Step-by-step explanation:
Consider the attached figure.
The equation is [tex]y=x-1[/tex]
At [tex]x=0;y=0-1=-1[/tex]
At [tex]y=0;0=x-1,x=1[/tex]
Plot points [tex](0,-1)\,,\,(1,0)[/tex].
Marcus starts walking at the point B(0, 9) so that his path is perpendicular to Sarah's at point A.
From the graph, Sarah's path and Marcus's path intersect at point [tex]A(10,9)[/tex]

The Big Time Band put on a community concert. A total of 1,236 people attended the concert. There were twice as many adults as children who attended the concert. How many adults attended the concert?
Answer:
412 adults
Step-by-step explanation:
Let the number of adults be x
Let the number of children be y
If a total of 1,236 people attended the concert, then;
x + y = 1236 .....1
If there were twice as many adults as children who attended the concert, then;
y = 2x
Substitute y = 2x into 1
x + 2x = 1236
3x= 1236
x = 1236/3
x = 412
Hence 412 adults attended the concert.

Can someone please help me solve this maths question?
Answer:
N and P are equal to 48 degrees
Step-by-step explanation:
1. 3y^2=12y^2−144
2. Subtract 3y^2 from both sides
3. add 144 to both sides
4. 9y^2= 144
5. Divide both sides by 9
6. y^2 = 16
7. Take the square root of 16 ( which is y=±√16)
8. y = 4 or y = -4
(in this case, Y would equal 4 since the angles are not negative lol)
9. Plug 4 into the equations
10. Compare each answer to see if they are equal

Answer:
∠ N = ∠ P = 48°
Step-by-step explanation:
Δ KMP and Δ LJN are similar ( AA postulate ), then corresponding angles are congruent, that is
∠ P = ∠ N
12y² - 144 = 3y² ( subtract 3y² from both sides )
9y² - 144 = 0 ( add 144 to both sides )
9y² = 144 ( divide both sides by 9 )
y² = 16 ( take the square root of both sides )
y = [tex]\sqrt{16}[/tex] = 4
Then
∠ N = 3y² = 3(4)² = 3(16) = 48² = ∠ P

The triangles below are similar. What is the length of the missing side?
2
9
6
8
Answer:
8
Step-by-step explanation:
it's multiplied by 2 as you go to triangle 2
Answer:
x = 8
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{5}{10}[/tex] = [tex]\frac{4}{x}[/tex] ( cross- multiply )
5x = 40 ( divide both sides by 5 )
x = 8
A display in a grocery store has 120 pieces of fruit. Apples make up 3/5 of the display, and oranges make up 2/5 of the display. If 1/2 of the apples are green, how many green apples are there?
Answer:
36 green apples
Step-by-step explanation:
First, you should divide 120 by 5 since it is 3:2 and the denominator is 5. Since each part there are 24 fruits, you should now multiply that number by 3 which is 72. Since 1/2 of the apple display are green, you would need to divided 72 by 2 which gets you the answer of 36 green apples.
