C ' (2, 5)A (16, 8)================================================================
Explanation:
I'm assuming you mean to say "scale factor of s = 1/3" since the green triangle is smaller than the red triangle.
Let's start at the point (4,2). This is the center of dilation. This fixed point does not move or change as you apply any dilation (as long as you keep this as the center of course). Every other point will move. For instance, the point (10,14) moves to (6,6) after applying the dilation.
----------------------
The x coordinate of the center point (4,2) is x = 4.
The x coordinate of the point (10,14) is x = 10.
Going from (4,2) to (10,14) will have us move a horizontal distance of 10-4 = 6 units.
Take 1/3 of this horizontal distance and we get (1/3)*6 = 2. This means that if we started at the center point (4,2) and move 2 units to the right, we will have the x coordinate to be x = 4+2 = 6, which matches up with the x coordinate of the point (6,6)
-------------------------
We'll do the same sort of thing with the y coordinates
The point (4,2) has the y coordinate y = 2
The point (10,14) has the y coordinate y = 14
The vertical distance between those points is 14-2 = 12 units
One third of this is (1/3)*12 = 4
If we started at (4,2) and moved up 4 units, then the y coordinate goes from y = 2 to y = 2+4 = 6. This also matches (6,6)
----------------------------
Hopefully by now you have a sense of how this all works. Let's use these tricks to find the location of point A.
The horizontal distance from (4,2) to (8,4) is 8-4 = 4 units. This triples to 4*3 = 12 units. We triple here because we're going in reverse of the process described in the previous two sections. If (8,4) and A swapped places, then we would take one third instead.
We'll use that 12 to count out 12 horizontal spaces from (4,2) to get to (16,2). I added 12 to the x coordinate of (4,2).
Repeat the process for the y values. The vertical distance from (4,2) to (8,4) is 2 units, which triples to 6. Add 6 onto the y coordinate of (16,2) and we arrive at (16, 8) which is the location of point A.
--------------------------------
Now let's find the location of point C'
The horizontal distance from (-2,11) to (4,2) is 6 units because |-2-4| = 6. Multiply this by 1/3 and we get (1/3)*6 = 2
To get to the location point C', we need to start at (4,2) and move to the left 2 units. That means (4,2) will move to (2,2) as a temporary location.
We apply the same idea for the y coordinates. The vertical distance from (4,2) to (-2,11) is 9 units. This leads to (1/3)*9 = 3 units being the vertical distance from (4,2) to the location of C'. We'll add 3 to the y coordinate of (2,2) to arrive at (2,5) which is the location of C'.

If BE = 2x + 2, BD = 5× - 3, and AE = 4× - 6, what are the values of x and AC?
Answer:
x = 7
AC = 44
Step-by-step explanation:
Find the diagram attached
According to the parallelogram,
BD = 2BE
5x-3 = 2(2x+2)
5x-3 = 4x+4
5x-4x = 4+3
x = 7
Hence the value of x is 7
Also AC = 2AE
AC = 2(4x-6)
AC = 8x - 12
AC = 8(7) - 12
AC= 56-12
AC = 44
Hence the measure of AC is 44

Step-by-step explanation:
The ratio 2 centimetres to 5 metres can be written in the form
1
:
n
.
Find the value of
n
.
Answer:
n = 250
Step-by-step explanation:
To express the ratio, the quantities must have the same measures
2 cm : 5 m
= 2 cm : 500 cm [ 1 m = 100 cm ]
Divide both parts by 2
= 1 : 250 → with n = 250
What is the measure of the indicated angle?
Answer:
76
Step-by-step explanation:
Let the indicated angle be x
all the angels add up to 180⁰
therefore,
x + 48 + 56 = 180
x + 104 = 180
x = 180 - 104
x = 76

What is the area of a triangle whose base measures 3.2 centimeters and whose height is 4.6 centimeters.
Answer:
7.36 cm²
Step-by-step explanation:
What is the area of a triangle whose base measures 3.2 centimeters and whose height is 4.6 centimeters.
The formula for the area of a triangle is given as:
1/2 × Base × Height
Base = 3.2 cm
Height = 4.6 cm
Hence,
Area of the triangle = 1/2 × 3.2 × 4.6
= 7.36 cm²

What is an equation of the line that passes through the points (4, -6) and
(8,-4)?
Answer:
y = 1/2x - 8
Step-by-step explanation:
(4, -6) & (8, -4)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(-4 - (-6)) / (8 - 4)
Simplify the parentheses.
= (2) / (4)
Simplify the fraction.
2/4
= 1/2
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 1/2x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (8, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = 1/2(8) + b
To find b, multiply the slope and the input of x(8)
-4 = 4 + b
Now, subtract 4 from both sides to isolate b.
-8 = b
Plug this into your standard equation.
y = 1/2x - 8
This is your equation.
Check this by plugging in the other point you have not checked yet (4, -6).
y = 1/2x - 8
-6 = 1/2(4) - 8
-6 = 2 - 8
-6 = -6
Your equation is correct.
Hope this helps!
