The difference between $0.20 and $0.60 is: 0.60 - 0.20 = $0.40
The rate of change in 4 years is $0.40
The rate of change in 1 year is $0.10
The vertex form: y = a(x - h)² + k
y = x² - 6x + 7 = x² - 2x · 3 + 3² - 3² + 7 = (x - 3)² - 9 + 7 = (x - 3)² - 2
Answer: y = (x - 3)² - 2
Used: (a - b)² = a² - 2ab + b²
Answer:
xc + -4x
Step-by-step explanation:
The distributive property allows the multiplication of a sum by multiplying each addend separately and then sum those products.
With this in mind, let's apply the distributive property to the expression:
x (c - 4)
= x * c + x * (-4)
= xc + -4x
Cheers.
