The phone company charges a base fee of $25 per month and an additional $10 for each "g" gig of data used. Which expression could represent the situation?

10g+25

Step-by-step explanation:

If you just want to figure out the amount of money in one month this would be the equation hope this helps :)

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

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.
