Answer:
5.33
Step-by-step explanation:
Move your numbers so that they're separate from the variables. You should now have x = -2.67 + 8; x = 5.33
This can be also written as y=-2x+2
First of all the - at the beginning = reflection across the x axis.
Then the first 2 is a vertical stretch of 2
the second 2 is a translation of 2 units up.
So
1.ref. across the x axis
2.vert. stretch of 2
3. translation of 2 units up
It is possible to prove that the right triangles are congruent through the right angle hypotenuse side theorem.
