Which of the follwoing is a reflection of (2,4) across the x axis

histogram or dot plot?

step-by-step explanation:

the answer is b.)

< 1=< 2

the square root of what number? if you add that, then someone will probably answer the question.

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.
