I just need help with the graphing!

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.

If (x + 8) is a factor of f(x), which of the following must be true? both x = –8 and x = 8 are roots of f(x). neither x = –8 nor x = 8 is a root of f(x). f(–8) = 0 f(8) = 0

Graph the following system of linear inequalities. identify at least two points in the solution: y < 5 - 2x | x + 5y > -7
