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 )
Answer:
The answer to your question is Yes, he can buy it.
Step-by-step explanation:
Data
Money saved = $35
Original Price = $42
Discount = 30%
Tax = 5 %
Process
1.- Calculate the price of the Video game with the discount
$42 --------------------- 100%
x --------------------- 30%
x = (30 x 42) / 100
x = $ 12.6
Price with discount = 42 - 12.6
= $ 29.4
2.- Calculate the price of the Video game plus taxes
$29.4 ------------------- 100%
x ------------------- 5%
x = (5 x 29.4) / 100
x = 147 / 100
x = 1.47
Price plus taxes = 29.4 + 1.47
= $ 30.87
3.- Conclusion
Bruce can buy the Video game because he saved $35 and the video game plus taxes cost $30.87.
