What is the y=value of the vertex
y=-x squared -10x+24

49

Step-by-step explanation:

y = -x² - 10x + 24

For a parabola ax² + bx + c, the vertex is at x = -b/(2a).

In this case, a = -1 and b = -10.  So:

x = -(-10) / (2 * -1)

x = -5

The y coordinate is:

y = -(-5)² - 10(-5) + 24

y = -25 + 50 + 24

y = 49

not 100% sure but a good guess
