The figure below shows the letter Z and four of its transformed images-A, B, C, and D: A coordinate plane is shown. The letter Z has endpoints at negative 6 comma 3, negative 6 comma 1, negative 4 comma 1 and negative 4 comma 3 and has a diagonal line that goes from top right to bottom left in between. A is a shape that has endpoints at 4 comma 3, 4 comma 1, 6 comma 3 and 6 comma 1 and has a diagonal line that goes from top left to bottom right. B has endpoints at negative 6 comma negative 1, negative 6 comma negative 3, negative 4 comma negative 1 and negative 4 comma negative 3 and has a diagonal line that goes from top right to bottom left. C has endpoints at negative 3 comma negative 1, negative 3 comma negative 3, negative 1 comma negative 1, negative 1 comma negative 3, and has endpoints that go from top left to bottom right. D has endpoints at 2 comma negative 1, 2 comma negative 3, 4 comma negative 1, and 4 comma negative 3 and has a diagonal that goes from top right to bottom left. Which of the four images was formed by a reflection of the letter Z? (5 points) A B C D
Answer:its c
Step-by-step explanation:
Answer:
The answer is A
Step-by-step explanation:
The answer is A because a reflection would be Reflected so its on the right side of the graph and the Z is facing the other way as if it were a literal reflection which it is.
Hope my awkward way of explaining this helps you on your test since i just passed mine and it said A was correct.
Devaughn is 13 years younger than Sydney. The sum of their ages is 79 . What is Sydney's age?
Answer: 46 years old
Step-by-step explanation: If Devaughn is 13 years younger than Sydney,
we can represent Sydney's age as x and Devaughn's age as x - 13.
Since the sum of their ages is 79, we have x + x - 13 = 79.
This simplifies to 2x = 92.
Dividing both sides by 2, we have x = 46.
So sydney is 46 years old.

what's y intercept on a graph of y = -5x + 6
The y-intercept on a graph of y = -5x + 6 is 6.
What are intercepts?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
We have a linear equation,
y = -5x + 6.
The general slope-intercept form,
y = mx + b.
Where m is the slope and b is the y-intercept.
Comparing,
b = 6.
Therefore, 6 is the y-intercept.

The line which represents the width of the room equal to 8 inches long on a blueprint, by the architect, has the size of the room 20 foot.
What is scale factor?Scale factor is the factor which is used to enlarge or smaller the original figure.
Scale factor is the ratio of representation measurement of the figure to the original figures.
On a blueprint, an architect drew a 12-inch line to represent the length of a 30-foot room. Thus, the scale factor of foot to inch is,
[tex]k=\dfrac{30}{12}[/tex]
Let suppose the line that represents the width of the room is 8 inches long, has the size of room in foot is x. Thus,
[tex]k=\dfrac{8}{x}\\\dfrac{12}{30}=\dfrac{8}{x}\\x=\dfrac{30\times8}{12}\\x=20[/tex]
Thus, the line which represents the width of the room equal to 8 inches long on a blueprint, by the architect, has the size of the room 20 foot.

1. Which equation represents a line that passes through the point (-2,6) and is parallel to the line whose equation is 8x – 4y = 6?
Answer:
y=2x+10
Step-by-step explanation:
First, let's put the equation into slope-intercept form. We get y=2x-3/2.
Parallel lines have the same slope, so the slope of the line will be 2.
We then substitute the point into the equation to find the y-intercept.
We get y=2x+10
Hope this helps :-)
