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 HELP PLEASE! How many solutions do those have?

Respuesta :

Answer:

y = 12x² - 9x + 4 has zero real solution.

10x + y = -x² + 2 has two real solutions.

4y - 7 = 5x² - x + 2 + 3y has zero real solution.

y = -2x + 8 has one real solution.
