What is the y value of the vertex
Alenkasestr [34]

Answer:

y value = 49

Step-by-step explanation:

You are going to be completing the square

y = - x^2 - 10x + 24           Take a minus outside the brackets for the first 2 terms.

y = - (x^2 + 10x) + 24

Take 1/2 the linear term (1/2 10 and square it. Put that value inside the brackets. 1/2* 10 =5; 5^2 = 25

y = - (x^2 + 10x + 25) + 24

Add 25 outside the brackets.

y = -(x^2 + 10x + 25) + 24 + 25. You should stop here and consider why you are adding 25 outside the brackets. It is because there is a - sign in front of the trinomial and what is inside the brackets is really - 25 when the brackets are removed. Therefore to balance that, you add 25.

Now complete the square.

y = - ( x + 5)^2 + 49

The value you seek is 49.

=============

I'll confirm this with a graph.
