question about break even point.
I am not to sure how to tackle this, so any help would be greatly appreciated.
"find the break even point of each pair of equation. round to nearest decimal answers to the nearest tenth."
E=26 +3.2x
I=4.5x
im not sure what E and i stand for.

is there something in the question you haven't included?

ohhhhh im sorry it's E=26 + 3.2x sorry, sort of new here.

UnkleRhaukusBest ResponseYou've already chosen the best response.2
i think the break even point is where the lines cross

UnkleRhaukusBest ResponseYou've already chosen the best response.2
ie, the point that solves both the equations

so how would i go about this? should i just graph it in my calculator or is there some formula for this?
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.2
well i wold simply solve the second equation for x (by dividing by 4.5) and then substituting this into the first equation

salparadise64Best ResponseYou've already chosen the best response.1
so im looking for i?

UnkleRhaukusBest ResponseYou've already chosen the best response.2
your looking for the \(x\) that makes I=E

i got x= i/4.5 then plugged it into 26+ 3.2 (i/4.5) am i on the right path?
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.2
yeah, E=26+3.2 (i/4.5) simplify this a bit and you will have E in terms of I

salparadise64Best ResponseYou've already chosen the best response.1
okay, so im stuck at E= 26 +3.2i/4,5 i dont think i can those two values.
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.2
actually i think there is an better way to do this problem The break even point is when I=E so solve 26 +3.2x=4.5x
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.2
can you find \(x\) now?
 one year ago

salparadise64Best ResponseYou've already chosen the best response.1
Yes thank you, you are too awesome. i got x=20
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.2
good stuff, can you round that to the nearest tenth?
 one year ago

salparadise64Best ResponseYou've already chosen the best response.1
do i need to? it broke evenly.
 one year ago

salparadise64Best ResponseYou've already chosen the best response.1
i think the instructions might be in case it didnt break down evenly.
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.2
To be a point the point must have an \(x\) and a \(y\) value you've found \(x=20\) , to find \(y\) substitute \(x\) into either equation to get \(y\), then write the point like this \((x,y)\)

salparadise64Best ResponseYou've already chosen the best response.1
Y=i =4.5 * 20= 90 (20,90)?
 one year ago

UnkleRhaukusBest ResponseYou've already chosen the best response.2
Thats it \[(20,90)\checkmark\]
