Answer:
"A reflection over the line y = x, followed by a reflection over the y-axis"
Step-by-step explanation:
We want to find the transformation that maps the point A (3, 4) into the point A' (-4, 3).
We can see that:
first we have an interchange between the x-component and the y-component.
Then we go from (x, y) to (y, x)
And now we change the sign of the x-component.
Then we go from (y, x) to (-y, x)
This is the transformation we have, now let's find a name for it.
The first transformation is a reflection over the line y = x.
The second is a reflection over the line x = 0.
Then our transformation can be:
"A reflection over the line y = x, followed by a reflection over the y-axis"

what is the value of x?

Answer:
A. 2
Step-by-step explanation:
Given:
DC = 1
CE = x + 4
AB = 11
BE = x + 1
Required:
Value of x
Solution:
(DC + CE) × CE = (AB + BE) × BE
(1 + x + 4) × (x + 4) = (11 + x + 1) × (x + 1)
(x + 5) × (x + 4) = (x + 12) × (x + 1)
x² + 4x + 5x + 20 = x² + x + 12x + 12 (distributive property)
x² + 9x + 20 = x² + 13x + 12
Collect like terms
x² - x² + 9x - 13x = - 20 + 12
-4x = -8
Divide both sides by -4
x = -8/-4
x = 2

If you jog 8 times around a track that is 600 meters long, how many kilometers have you covered?
Answer:
0.6 km
Step-by-step explanation:
If If you jog 8 times around a track that is 600 meters long, then 4.8 kilometers you have covered
What is Unit of Measurement?A Unit of measure is the actual unit in which the associated values are measured.
Given,
If you jog 8 times around a track that is 600 meters long,
We need to find how many kilometers you have covered.
8 times around a track that is 600
It means we have to multiply eight with six hundred.
8×600
=4800
We know that 1 km is 1000 m
So divide 4800 by 1000 to find in kilometers
4800/1000=4.8km
Hence If you jog 8 times around a track that is 600 meters long, Then 4.8 Kilometers you have covered.

A towns population went from 40,000 to 50,000. What was the percent of change in the population?
Answer:
The percent of change in the population was of 25%.
Step-by-step explanation:
Percent change:
The percent change is given by the change multiplied by 100, and divided by the initial value.
A towns population went from 40,000 to 50,000.
Change: 50000 - 40000 = 10000
Initial value: 40000
10000*100/40000 = 25%
The percent of change in the population was of 25%.
If point B has coordinates (-8, 1), what are the coordinates of the point when it is reflected across the y-axis?
Answer:
(8,1)
Step-by-step explanation:
When flipping across the y axis, the y coordinate stays the same, while the x coordinate changes it's sign.
(x,y) - > (-x,y)
(-x,y) -> (x,y)

2. The German Shepard actually weighs 28 pounds. Lisa thought the
dog weighed 44 pounds. What is the percent error?
Answer:
Lisa's percentage of error regarding the weight of the dog was 57.14%.
Step-by-step explanation:
Given that the German Shepard actually weighs 28 pounds, but Lisa thought the dog weighed 44 pounds, to determine what is the percent error the following calculation must be performed:
28 = 100
44 = X
(44 x 100) / 28 = X
4,400 / 28 = X
157.14 = X
157.14 - 100 = 57.14
Thus, Lisa's percentage of error regarding the weight of the dog was 57.14%.

Answer:
x = 25°
y = 25°
Step-by-step explanation:
✔️(x + 35)° + 30° + 90° = 180° (sum of triangle)
x + 35 + 30 + 90 = 180
Add like terms
x + 155 = 180
x + 155 - 155 = 180 - 155
x = 25°
✔️(y + 30)° + 35° + 90° = 180° (sum of triangles)
y + 155 = 180
y = 180 - 155
y = 25°
