Algebra ii :

if f(x) = 3x + 5/2, what is f(a+2)

a) 3a+5/a+12
b) 3(a+2)=5/a+2
c) 3(f(a))+5/f(a)+2

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

Aclassmate thinks that solving a system by graphing gives an exact answer when the lines appear to cross at a grid point, but only an approximate answer when they don't. explain why this isn't true.

Identify the parent function that can be used to graph the function f(x)=3(x-9)2
