Evaluate the discriminant, tell how many solutions the equation has and whether those solutions are real or imaginary. show your work. y = -5x^2 + 6x - 4

Discriminat = 44 and the equation has two imaginary solutions.

Step-by-step explanation:

For a quadratic equation in the form of y = ax^2 + bx + c, its discriminant is equal to b^2 - 4ac.

If discriminant < 0, then the equation has two imaginary solutions. If it is 0, then the equation has 1 real solution and if it is > 0, 2 real solutions.

In this case, y = -5x^2 + 6x -4.

So its discriminant = 6^2 - 4*(-5)*(-4)

= 36 - 80

= 44 so it has two imaginary solutions.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
