wtf somebody help meeeeeeeeeeeeeeeeeeeeeeeee damn it

OpenStudy (anonymous):

with what?

OpenStudy (anonymous):

Write a function rule for finding the amount of daily pay, p, in the following situation: A bus driver gets paid $100 each day plus $0.20 per kilometer, k. (1 point) 100 = 0.20 × k p = 0.20 × 100 × k p = 0.20k + 100 0.20k = 100 + p i think its Yes, they show a linear function; y = 2x + 2.

OpenStudy (anonymous):

i didn't mean to put that last thing

OpenStudy (anonymous):

haha

OpenStudy (anonymous):

(:

jimthompson5910 (jim_thompson5910):

The $100 paid is the fixed cost, this is the amount they pay no matter how many kilometers driven so b = 100 The variable cost is $0.20, which means the slope is m = 0.20 So y = mx + b y = 0.20x + 100 p = 0.20k + 100 is your equation

thanks (((: can you help me with another one ?

jimthompson5910 (jim_thompson5910):

when talking about any cost equation in the form y = mx + b the variable b is your fixed cost the variable m is the variable cost

jimthompson5910 (jim_thompson5910):

sure

OpenStudy (anonymous):

Write an equation for the line shown in the graph. 10 = 4x y = 2x + 10 y = 10x – 2 y = ­–x + 10

jimthompson5910 (jim_thompson5910):

can you name me two points that are on this line?

OpenStudy (anonymous):

10 and 2

jimthompson5910 (jim_thompson5910):

so the point (10,2) ??

jimthompson5910 (jim_thompson5910):

or did you mean something else?

OpenStudy (anonymous):

never mind i don't need help

jimthompson5910 (jim_thompson5910):

ok glad you figured it out
