Help!! I will Fan and Medal!!!
Part A: Max rented a motorbike at $465 for 5 days. If he rents the same motorbike for a week, he has to pay a total rent of $625. Write an equation in the standard form to represent the total rent (y) that Max has to pay for renting the motorbike for x days. (4 points) Part B: Write the equation obtained in Part A using function notation. (2 points) Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals. (4 points)

yeah ok I haven't helped people in ages, so forgive me if I explain things weird (feel free to ask if you get confused in any part of my explaining) there's this way to format equations called the y-intercept form it looks kinda like: y = mx + b you know that? :)
Could you give me 15 min, please?
yes @3mar
yeah well the first step would be to plug in numbers where you can we can make 1 equation for the two different time lengths (time lengths); like 5 days and a "week" (7 days), are "x" and the total the person paid (465) and (625), are "y" we plug this in and get 465 = m*(5) + b and 625 = m*(7) + b @firechild17 do you see where I got that?
yes @jigglypuff314 i know that formula and yes i see how you got that
awesome ^_^ using those two equations we want to solve for m and b
okay and how do we do that again? @jigglypuff314
we can say 465 = m*(5) + b --> b = 465 - 5m and 625 = m*(7) + b --> b = 625 - 7m then since b = b 465 - 5m = 625 - 7m and we can solve for m
okay
once we get a number for m we can plug it back into b = 465 - 5m to get b
This doesnt make sense...I am still confused @jigglypuff314
alright, where did I lose yah? :D
we have two equations we know that because we are going to the same store, the (per day rate) and (flat rate) [(m) and (b)] are equal in other words, the (m) from the first equation should be equal to the (m) in the second equation; (same with the b) because of this, we can set the two equations equal to each other to find m and b
I am horrible at math and truthfully when you started talking about finding B
yeah, I realized that I might have rushed through explaining that xD so it was my bad, sorry basically, we got two equations 465 = m*(5) + b and 625 = m*(7) + b right? then we want to find (m) and (b)
yes we have to find M and B so we divide the first equation by 5 and the second one by 2?
hmm I don't think we have to multiply or divide anything I think we can solve for (b) first with just adding and subtracting easy stuff
okay what do you mean?
well if we move everything to one side, for each equation for example, 465 = 5m + b [subtract 465 from both sides] -> 0 = 5m + b - 465 right?
okay
then 625 = m*(7) + b becomes 0 = 7m + b - 625 right?
yes
and 0 = 0 so we can set the equations equal to each other 5m + b - 465 = 7m + b - 625 right?
but then if we subtract both sides by b 5m + b - 465 = 7m + b - 625 - b - b --------------------------- we get 5m - 465 = 7m - 625 and now we can solve for m
@firechild17 Do you still need help? Sorry for being late for you! The electricity was off! @jigglypuff314 has walked with you very well! Thanks for him! If you still need help, I will not be late for you.
@3mar i am still confused
