Hello!
So in this question, you need to do it backwards. This means, taking the vertices of the new triangle and reflecting it across the X axis, and then reflecting it 180 degrees.
The formula for reflecting across the X axis is--
(X,Y) -> (X,-Y) *Note, in this case, it may not always be negative Y. The negative symbol only stands for the opposite. So it the point is negative originally, then the new point would be positive.
__________________________________
So, now you take your points, and use the formula.
(-4,-4) -> (-4,4)
(-2,-4) -> (-2,4)
(-3,-1) -> (-3,1)
Now, you have your new points. But, you still need to rotate it 180 degrees.
The formula to rotate 180 degrees is--
(X,Y) -> (-X,-Y)
Then, you take your new points, and use the formula for each coordinate.
(-4,4) -> (4,-4)
(-2,4) -> (2,-4)
(-3,1) -> (3,-1)
There is your answer. The new points would be--
(4,-4)
(2,-4)
(3,-1)
Hope this helped!

I believe that a flat surface continuing in all directions is called a plane.
To make perpendicular lines use your compass and make it over half the length of the bottom line. Make an ark on both sides of the line. then repeat on the opposite side of the line. Your two arks should have intersected at two points. Then us your straight edge to connect the two points. This video should help with the parallel lines. https://www.youtube.com/watch?v=im81vHIhZS8
The missing property is : x=24 Addition Property of Equality
Step-by-step explanation:
We need to identify the missing justification.
Step Justification
negative four plus one fourth times x equals two Given
−16 + x = 8 Multiplication Property of Equality
x=24 ------------
Solving:
-4+1/4x=2 (given)
Multiply both sides by 4
-16+x=8 (Multiplication Property of Equality)
Add 16 on both sides of equation
-16+x+16=8+16
x=24 (Addition Property of Equality)
So, the missing property is : x=24 Addition Property of Equality

Answer:
82
Step-by-step explanation:
Given
6x - 2y ← substitute x = 16 and y = 7 into the expression
= 6(16) - 2(7)
= 96 - 14
= 82
