The new coordinates after reflected across y-axis and shifted 2 units down
When a point is reflected across the y-axis, the rule is:

So:




When a point is translated 2 units down, the rule is:

So:





So, the new coordinates are:


The answer is c.
I will explain
p - 2r = q
1. Move variable to the right by adding it’s opposites on both sides
p - 2r + 2r = q + 2r
2. Eliminate the opposites (-2r and +2r)
p = q + 2r
8*4=32
7*4=28
340÷32=10.625
350÷28=12.5
12.5-10.625= 1.875
When you multiply 2 irrational numbers, the result is always irrational. This applies to squaring as well since it is still multiplying irrational numbers together (though the terms are the same)
Final answer: never rational
