Answer:
I'm sorry but I don't understand what language this is.
Step-by-step explanation:
If you could say it in English maybe I could help :)
Use the equation of -b/2a, so if you have a line you can just plug in the numbers.
A) f(x)=0.2x
B)f(12)=0.2(12)=2.4 dollars
Answer:
yes it does. good job on your A.
Step-by-step explanation:
In y = mx + b form, the slope can be found in the m position and the y intercept can be found in the b position.
y = mx + b
y = 2x + 15
slope(m) = 2 and y int (b) = 15
The initial amount is the y intercept, which is 15. The rate of change (the slope) is 2
example :
baskets picked in 1 hr :
y = 2(1) + 15
y = 2 + 15
y = 17
baskets picked in 2 hrs :
y = 2(2) + 15
y = 4 + 15
y = 19
so the slope ( rate of change) is basically saying for every hr of picking, you pick 2 baskets...so your picking 2 baskets per hr.
The y intercept (15) is telling us that they already had 15 baskets to start with.
