$(-8+-\frac{8}{11} ) + (-\frac{8}{12}) = -\frac{96}{11} + (-\frac{2}{3}) = -\frac{288 + 22}{33}) = -\frac{310}{33}\\ (-8) + (-\frac{8}{11} + (-\frac{2}{3})) = (-8) + (-\frac{46}{33})= -\frac{310}{33}$

Why is graphing not always the best option for solving systems?

RideAnS [48]

1, Might not be precise
2, Can be hard to plot the graphs
3, If there are many solutions that will be really hard to plot sometimes.

This is just from the top of my head.

If x2=4(5-1) what is the value of x

Deffense [45]

X2=4(5-1)
x2=4(4)
x2=16
x=4

Check: 4 squared (4 times 4) equals 16. When you square a number, you multiply the number by itself.
