I really need help with 4 if anyone knows it please help im begging :(

Desmond wants to sell his car that he paid $8,000 for 2 years ago. the car depreciated, or decreased in value, at a constant rate each month over a 2-year period. if x represents the monthly depreciation amount, which expression shows how much desmond can sell his car for today? 8,000 + 24x 8,000 − 24x 8,000 + 2x 8,000 − 2x

Don't know how to find x given these segment lengths

Complete the solution of the equation. find the value of y when x equals -5. -4x - 8y = -52
