Step-by-step explanation:
Find the unit rate of each pair of socks for the dozen. 12/9=1.3333
so then multiply 18 by 1.33 to get 23.92. So you could sell the 18 pair pack of socks for anything less than $23.92
Hope this helps ^-^
Answer:
(6,-1)
Step-by-step explanation:
let coordinates of K be (x,y) then

We have the equation for company 1: y = 3x + 5. That means it costs $3 to rent a movie with a $5 fee no matter how many movies you rent. It would benefit us to have the equation for company 2, so we need to find it using 2 points on the line. I picked the points (2,14) and (0,12). Find the slope of this by using the slope formula:

which gives us a slope of 1. Now we can use that slope and the slope-intercept form of a line to find the y-intercept, which serves as the fee for renting from company 2. 14=1(2)+b and 14 = 2 + b and b = 12. The equation then for company 2 is y=1x+12. This means it costs $1 to rent movies, but your fee to rent, no matter how many movies you pick, is $12. The "rate of change" in the choices refers to the slope. The slope in company 1's equation is 3 and the slope in company 2's equation is 1. The best description is the first choice that says "There is a higher rate of change at Company 1".
