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.

Best ResponseYou've already chosen the best response.1ohhhhh im sorry it's E=26 + 3.2x sorry, sort of new here.

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

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

Best ResponseYou've already chosen the best response.1so how would i go about this? should i just graph it in my calculator or is there some formula for this?

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

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

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

Best ResponseYou've already chosen the best response.1i got x= i/4.5 then plugged it into 26+ 3.2 (i/4.5) am i on the right path?

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

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

Best ResponseYou've already chosen the best response.2actually 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

Best ResponseYou've already chosen the best response.2can you find \(x\) now?

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

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

Best ResponseYou've already chosen the best response.1do i need to? it broke evenly.

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

Best ResponseYou've already chosen the best response.2To 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 \((x,y)\)

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