Answer:
9/12
Step-by-step explanation:
Answer:
.4 repeating
Step-by-step explanation: divide the top number by the bottom number so 4 divided by 9
You gotta combine like terms which would be 9x and 12x which gives you 21x .
Answer: D) reflection across y = -x
Explanation:
When we reflect over y = x, we basically swap x and y. So for instance, the point (3,1) becomes (1,3).
When reflecting over y = -x, we will do the same thing but we'll make each coordinate swap in sign from positive to negative (or vice versa). The rule for reflecting over y = -x is 
So if we apply that rule to point A(3,1) then it becomes A ' (-1, -3).
Similarly, B(1,5) moves to B ' (-5, -1)
Finally, C(6,9) becomes C ' (-9, -6)
