Exponents Blog Post

1. In this blog post we are asked to find out numbers that will work where the question marks are. We have to find out what the question marks equal so it equals the same as the other side. There are many solutions but the one I found fit best is when ?#1 is 2X to the 5 ?#2 is W to the 2 ?#3 is just Y #4? is just W. After you make sure you follow PENDAS you will find out that they equal the same thing.

Stacking Cups problem


For this blog post we have to find out when the cups that we are given (above) all equal the same hight with the same amount of cups.
Cup1: Y=.2x+5.5
Cup2: Y=1x+4.5
Cup3: Y=1.5x+7.5
Cup4: Y=.6x+9
For 1 and 2 the cup are equal at 1.5 cups on each.
For 1 and 3 would be the same at -1.53 so there is no soulution.
For 1 and 4 would be the same at -8.75 so there is no soulution.
For 2 and 3 would be the same at -6 so there is no soultion.
For 2 and 4 cups are equal 11.25 cups.
For 3 and 4 cup are equal at 1.66 cups.
I used desmos and graphed all the lines on a paper but didn't go into the negitives.
