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?

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.

Step-by-step explanation:

it has changed from the width and the height.

step-by-step explanation:

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
