R(s + t) = st
Rs + Rt = st
Rs - st = -Rt
s ( R - t) = -Rt
*s = - Rt / (R - t) Multiply through by -1 on the right.
*s = Rt / (t - R) Put in the brackets in your answer. What you have been writing means
s = Rt/r - R you need the brackets. The stars mean that either could be an answer. I think your problem could be the brackets. Now I'm reasonably certain this is correct.
Answer:
When x <= 8000
The cost remains constant at 0.35 when x increases from 0 to 8000
The slope of cost function over this part is 0
When 8000 < x <= 20000
The cost remains constant at 0.75 when x increases from 8000 to 20000
The slope of cost function over this part is 0
When 20000 < x <= 42000
The cost decreases when x increases from 20000 to 42000
The slope of cost function
m= -5 × 10^-6
Answer:
There is a strong but negative correlation. The - cuases a doawnward line but .89 is close to 1
Step-by-step explanation:
Answer:
y = -5x + 90
Step-by-step explanation:
y = mx + b is slope intercept form
b is the y intercept, meaning that 90 is the y-intercept
m is the slope (rise over run), 20/4, 5/1, 5
y = -5x + 90
this wasnt the best explanation but I hope it helped
