What is the resulting equation when the expression for y in the second equation is substitued into the first equation ? 3x+y=1 y=6-4x

The graph shows the function f(x) = (2.5)x was horizontally translated left by a value of h to get the function g(x) = (2.5)x–h.

How do i simply this expression (quadratic formula basis) on a ti-84 or normal calculator?

Asap (i need to finish this quick) graph complete the sequence of transformations that produces △x'y'z' from △xyz. a clockwise rotation ° about the origin followed by a translation units to the right and 6 units down produces δx'y'z' from δxyz.
