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,
