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.

2. exoticbunnylover123 says:

if y+4 = 0 or y=-4 we have division by 0 and therefore

y=-4 is excluded

D) the x-intercept represents adam's commission pay when he had zero total sales

4. erinwebsterrr says:

excluded value is x = - 4

The denominator of the rational expression cannot be zero as this would make the fraction undefined. Equating the denominator to zero and solving gives the value that y cannot be.

solve y + 4 = 0 ⇒ y = - 4 ← excluded value
