Answer:
vertex = (- 10, - 10 )
Step-by-step explanation:
The equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
h(x) = x² + 20x + 90
add/subtract ( half the coefficient of the x- term )²
h(x) = x² + 2(10)x + 100 - 100 + 90
= (x + 10)² - 10 ← in vertex form
with (h, k ) = (- 10, - 10 )
Answer: Im pretty sure it is the equal sign with the line between it
pretty sure that is it tho
Hope that helped
Step-by-step explanation:
Answer:
x-intercept=(-1,0) y-intercept =(0,-3)
Step-by-step explanation:
24^2 + 45^2 = 51^2
576 + 2025 = 2601
2601 = 2601
