The average diameter of a tree is measured over time. The equation y = 3/4x, where x is time in years and y is the diameter in inches, models this relationship. what is the predicted diameter, in inches, of the tree after 12 years

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

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.
