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?

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
