Please help me, I will give brainliest, I am struggling badly.

B y= 2/5x

Step-by-step explanation:

If y is red balloons and there are 2 red for every 5 balloons, multiplying 2/5 by the total number of balloons gives you how many red balloons you have

e) none of the above because the measure of angle cba is 101°

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.
