Answer:
vertex = (1, - 9 )
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = x² - 2x - 8
To complete the square
add/ subtract ( half the coefficient of the x- term )² to x² - 2x
f(x) = x² + 2(- 1)x + 1 - 1 - 8
= (x - 1)² - 9 ← in vertex form
with vertex = (1, - 9 )
F (5x^2 - 1) = 75x^4 - 35x^2 + 6

Answer:
30 = 5n
n = 6
Step-by-step explanation:
A box of strawberry cost = $5
A person has = $30
Number of boxes a person can buy = n
Equation to calculate the most number of boxes a person can buy with $30
Amount with the person = cost of a strawberry × number of strawberry
30 = 5 * n
30 = 5n
n = 30/5
n = 6
