Solve the system of linear equations below.
6x + 3y = 33
4x + y = 15
x = 2, y = 7
x = -13, y = 7
x = - 2
3 , y = 12 2
3
x = 5, y = 1

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

10+4√2 is the answer. i dont have the time to explain.
