Substitute 2x + 11 where you see y in the second equation and solve for x.
3x + 4(2x + 11) = -11
3x + 8x + 44 = -11
11x + 44 = -11
11x = -55
x = -5
Now, substitute -5 where you see x in the first equation and solve for y.
y = 2(-5) + 11
y = -10 + 11
y = 1
The answers are x = -5 and y = 1.

Describe how to transform the graph of f(x) = x2 to obtain the graph of the related function g(x).
olga55 [171]

9514 1404 393

Answer:

  1. left 1 unit
  2. down 2 units

Step-by-step explanation:

The transformation g(x) = f(x -h) +k is a translation of f(x) to the right by h units and up k units.

1. h = -1, so the graph of g(x) is the graph of f(x) shifted left 1 unit. (blue)

__

2. k = -2, so the graph of g(x) is the graph of f(x) shifted down 2 units. (green)
