Graph x-5y=20 please show me the steps

1 answer:

6 0

Simplify
5y=-x+20
Y=-1/5+4
On the y-axis of the graph go to 4 (0,4)
Then you will do down 1 and then go 5 right and keep repeating down 1 right 5 from the last point u plotted until you can’t plot anymore.

If (m+n)^2=m^2+n^2, what is (3^m)^n?

svp [43]

Answer:

$(3^m)^n=1$

Step-by-step explanation:

$(m+n)^2=m^2+n^2\\m^2+2mn+n^2=m^2+n^2\\(m^2+n^2)-(m^2+n^2)+2mn=0\\2mn=0\\This\ equation\ has\ two\ solutions\ : m=0,n=0\\\\But\ either\ way\ will\ result\ in\ the\ same\ answer.\\If\ m=0\ then,\\(3^0)^n\\=1^n\\=1\\\\If\ n=0 \ then,\\(3^m)^0\\=1$
