Which ratio is equivalent to 1 : 5?

2:10

Step-by-step explanation:

multiply both numbers by the same number(ie. 2,3,4) and the rotio will still be the same

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.

i don't think there is enough
