Hi I'm new here and I need some help please.
1. S=3/1-r if r= -3/4 , S=?
2. t=16(-1/2) ^x-1 if n=8
3. T= -1/2(2)^n-1 if t=-32 , n=?
4. write the quadratic equation whose roots are 2/3 and -1
5.What are the restrictions on the graph of y= x+2/ (x-a)(bx-1)
6. How many solutions are there for the follow non-linear system?
y= 2/x and y= (x+1)^2 -2
If anyone could me with these it would be great! Thanks a lot!
