Joe wants to buy at least 12 books at the book store. Comic book cost 3 dollars each and fiction books cost 5 dollars each. He has 100 dollars'
worth of Birthday money. Write linear inequalities that correctly models
this situation. At most how many fiction books does Joe needs to buy if
he wants buy exactly 10 comic books?

y=1/4x-4

step-by-step explanation:

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
