Determine the number of real solutions each quadratic equation has. y = 12x2 - 9x + 4 __ real solution(s) 10x + y = -x2 + 2 __ real solution(s) 4y - 7 = 5x2 - x + 2 + 3y __ real solution(s) y = (-x + 4)2 __ real solution(s) someone ! how many solutions do those have?

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 - 2xdesmond 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
