Line segment AC and BD are parallel. What are the new endpoints of the line segments AC and BD if the parallel lines are reflected across the x-axis?
A. A'(-2, 5) C'(5, 1) and B'(-2, -4) D'(5, 0)
B. A'(-5, -2) C'(-1, 5) and B'(-4, -2) D'(0, 5)
C. A'(2, -5) C'(-5, -1) and B'(2, -4) D'(-5, 0)
D. A'(5, 2) C'(1, -5) and B'(4, 2) D'(0, -5)
Option C : A'(2, -5) C'(-5, -1) and B'(2, -4) D'(-5, 0) is correct.
We have two line segments AB and CD parallel to each other.
We have to find the new endpoints if the parallel lines are reflected across the x - axis.
How will you find the image of the point across the x - axis?For a point P(x, y), its reflection across the x-axis is P'(x, -y).
From the figure - the coordinates of points A, B, C, D are -
[tex]A(2,5)\\B(2,4)\\C(-5, 1)\\D(-5, 0)[/tex]
We know the image of the point P(x, y) across the x-axis is P'(x,-y). Therefore, the coordinates of the points, when they are reflected across the x-axis are-
[tex]A(2,5) - > A'(2, -5)\\B(2, 4)- > B'(2, -4)\\C(-5, 1)- > C'(-5, -1)\\D(-5,0)- > D'(-5,0)[/tex]
Hence, Option C : A'(2, -5) C'(-5, -1) and B'(2, -4) D'(-5, 0) is correct.

y= 0.50x + -2.00
Step-by-step explanation:
Answer:
y=1/2x-2
Step-by-step explanation:
y=mx+b is the slope intercept form of a line.
you need to find m and b
m is the slope (rise over run) in this case it is 1 up, then over 2.
and b is the Y intercept. or in other words, the spot where the line cuts through the y-axis(vertical axis). in this case, it is -2.

Explain how the shapes shown have been sorted.
Answer:
Shapes in set A are all Quadrilaterals which are Parallelograms, whereas shapes in set B are all Quadrilaterals but one different than the other.
Hope this helps!
In both cases, we have sets of 3 quadrilaterals, such that in the first case the 3 belong to the same subset, and in B they don't.
How the shapes are sorted?
On case A, all the shapes are quadrilaterals, and the 3 figures are rhombi. So all belong to the same type of quadrilaterals, which is the type of figure with four sides, such that the opposite sides are parallel and have the same measure.
For case B we also have 3 quadrilaterals, but this time we have a rectangle, a square (which is a type of rectangle) and a non-rectangle quadrilateral. So this time, the 3 figures don't belong to the same type of quadrilaterals.

Step-by-step explanation:
Rule 1 closed circle is ≥ right open circle shows > right
Rule 2 closed circle is ≤ left open circle shows < left
Rule 3 with inequalities on line x > 2 means it starts from this value and moves right.
Rule 4 with inequalities on line x < 2 means it ends in this value.

what's the missing measurement ? pls help :]
Answer:
first one: 33 degress
second one: 67 degrees
Step-by-step explanation:
the total measurement for every triangle is 180 so js add up what they give you and subtract it from 180.
hope this helps
Answer:
Step-by-step explanation:
Sum of all angles of a triangle = 180
1) 60 + 87 + b = 180
147 + b = 180 {Subtract 140 from both sides}
b = 180 - 147
b = 33
2) b + 83 + 30 = 180
b + 113 = 180 {Subtract 113 from both sides}
b = 180 - 113
b = 67

What is the probability that I will randomly pick a 2, put it back, then randomly pick a 4?
Answer: [tex]\frac{1}{9}[/tex]
Step-by-step explanation:
The probability that you get a 2 is [tex]\frac{4}{52}[/tex] and that simplifies into [tex]\frac{1}{3}[/tex]. It is the same probability that you get a 4 because you put the 2 back. [tex]\frac{1}{3}[/tex] x [tex]\frac{1}{3}[/tex] = [tex]\frac{1}{9}[/tex],

QUESTION: How does finding the volume of a 3- dimensional object differ from finding the surface area?
Answer:
For the surface area, you are calculating the outer surface of an object. You calculate the 2-dimensional area of the outsides and add them up.
For the volume, you are calculating the inside space of an object. You calculate based on length, width, and height.
