Answer:
where are the others
Step-by-step explanation:
is there supposed to be other numbers?
Refrection of (-20, 4) across x-axis gives (-20, 4) = (-20, -4)
Refrection of (-20, 4) across y-axis gives (20, 4)
Refrection of (-20, 4) across y = -x gives (20, -4)
Refrection of (-20, 4) across y = 7 gives (20, 10)
178÷2 is 89

For these equations, we are going to use the slope formula, as defined below (
is slope and
and
are coordinate points):

We can simply "plug in" the coordinates we are given:


Our answers are:


12x is equal to (13-9)3x, so put a tick there.
15x is equal to 6x/2 * 5
24 x is equal to the middle row, which simplifies to (12)2x = 24x.
