Using the matrix solver on your calculator, find the solution to the system of
equations shown below.
4x - y = 3
6x - 2y = 2
O
A. More than 1 solution
O
O
O
B. x = 2, y = 5
C. No solution
D. x = 5, y = 2

I've used 2 methods Gauss and Cramer to determine the solution choose the one that fits you. Anyway as you can see the answer is D.

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
