The product of three point five and a number v
The goal is to raise AT LEAST $180, so this automatically indicates that the amount of keychains sold with the price must be the same or more than $180.
k = number of keychains
each keychain is $2.25
2.25k ≥ 180
divide both sides by 2.25 to get the k alone
k ≥ 80
The answer is 2.25k ≥ 180, k ≥ 80
(Hope this isn't confusing)
The rate of change for this function is 1/2.
In order to find the rate of change, you use the slope equation.
m (slope) = (y2 - y1)/(x2 - x1)
m = (4 - 2)/(9 - 5)
m = 2/4
m = 1/2
Answer: (1,2)
Step-by-step explanation:
Reflecting across the y-axis means 
So,
