If x = 8 3x = 24 6x = 48 24 * 48 = 1152 1152 - 15 = 1137
ashley skjaveland - Thank you so much Shannon! Yes, no need to feel sputid at all lol they are film images taken with a very loved family Zenit-E. Actually it is the camera that I learned manual exposure on when I was a kid and have played with ever since. It's old and cranky, the shutter is ridiculously loud and it leaves imperfections everywhere I love it. Thanks again!
You know that an equation has no solution when...Ex. 2>5 is falseTo show its false, put and O with a / through it----------To find it false, in terms of graphing, it is when you have parallel lines (Not crossing at any point if, in a perfect world, the lines went on forever).So for an exampley=2-3x6x+2y=7 (y=-3x+7/2 in Y=mx+b form)With this equation the lines do not pass through each other, and once more in a perfect world, if they kept going on the lines would never cross.
