$9.75
$16.50
$6.75
$7.50

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

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.

if you need just tell me and i will come to the rescue.

step-by-step explanation:

it would open into a square depending on the type of envelope i’m not sure about the second part
