Step-by-step explanation:

Well Well, so from Lesson 4 to 6 The $ added is 55 then from lesson 6 to 9 the $ added is 82.50. So you subtract 82.50-55=$27.50 which is the cost per lesson. Then to find out the initial fee you do 4*27.50=110 which means that you subtract 145-110=$35 and you get the initial fee. What you do to get the the initial fee is you go back to 0 lessons that's why I multiplied 4*27.50 and subtract that from the cost 145 and u get the initial fee! Hope this helped you comprehend what they're asking you!

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.
