First of all, look at the figure, The ABC orientation is changed from clockwise to counterclockwise, so an odd number of reflections are involved.
Second, look at the answer choices. Right away, you notice that the last choice (E) involves two reflections. That cannot be the transformation you see. Since that is what the question is asking for, the appropriate choice for the transformation NOT done is ...
... E. reflection across the x-axis followed by a reflection across the y-axis
_____
I have to admit, I went through each of the choices to see if it would work to produce the image you see. All choices except E will do that. All that work turned out to be unnecessary.
Answer:
See attached
Step-by-step explanation:
<em>Refer to attached</em>
Point B has coordinates of (8, 12) relevant to point P
So the coordinates of the image are
The point is
Answer:
Step-by-step explanation:
If A is parallel to B, then angles 2 and 4 are same side interior and they are supplementary. Thus,
2x + 10 + 4x + 80 = 180 and
6x = 90 so
x = 15
Answer:
(-4, 2)

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-6x + 5y = 34
-6x - 10y = 4
<u>Step 2: Rewrite Systems</u>
-6x + 5y = 34
- Multiply everything by -1: 6x - 5y = -34
<u>Step 3: Redefine Systems</u>
6x - 5y = -34
-6x - 10y = 4
<u>Step 4: Solve for </u><em><u>y</u></em>
<em>Elimination</em>
- Combine 2 equations: -15y = -30
- Divide -15 on both sides: y = 2
<u>Step 5: Solve for </u><em><u>x</u></em>
- Define equation: -6x - 10y = 4
- Substitute in <em>y</em>: -6x - 10(2) = 4
- Multiply: -6x - 20 = 4
- Add 20 on both sides: -6x = 24
- Divide -6 on both sides: x = -4
