The specific heat of a solid Y is 11.5 cal/g°C. A sample of this solid at 135 K is heated to 260 K. The solid absorbs 7.90 kcals. What is the
sample of solid in grams?

step-by-step explanation:

they will manufacture 8496 cars

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.
