Sasha says that for any △,white up pointing triangle , x y z , comma the reflection over the y‑axis composed with the reflection over the x-axis is equivalent to a translation of △.white up pointing triangle , x y z , . Explain Sasha's error.

i think the correct option is the second option.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
