Besties this is 100 points & i'll give brainliest istg i need to know this Find the unknown values of b and c in the equation y = -x² + bx + c given its vertex is (-7, -5).

Step-by-step explanation:

to figure out b we can consider the following formula:

the form of vertex coordinate given by

so according to the question

by order pair we obtain:

now substitute the value of h and a to the formula:

simplify multiplication:

cross multiplication:

divide both sides by -1:

now we need to figure out C to do so substitute -7 for x and -5 for y which yields:

simplify square:

simplify multiplication:

simplify addition:

cancel 49 from both sides:

hence,

b=-14C=-54

Problem:Find the unknown values of b and c in the equation y = -x² + bx + c given its vertex is (-7, -5).Let's Solve it!This is a problem where you want to able to ake use of tue Vertex Form in order to get the values of b and c fir the standard form of the parabola. Vertex (-7,-5) or (h,k) in the standard form. These are the x and y coordinates of the vertex. Note the standard form is:

Since we have the given of:

Note the vertex form is:

Hence, The answer for b and c is:

Let's confirm it :You can use x coordinate of the vertex like this,

You can also confirm the y coordinate of the vertex in the standard form by plugging the x coordinate.

So, the final answer for b and c is:
