$\cfrac{16^{x+1}}{8^{2x+2}}=16 \\ \\ \cfrac{(2^4)^{x+1}}{(2^3)^{2x+2}}=2^4 \\ \\ \cfrac{2^{4x+4}}{2^{6x+6}}=2^4 \\ \\ 2^{4x+4-(6x+6)}=2^4 \\ 2^{4x+4-6x-6}=2^4 \\ 2^{-2x-2}=2^4\\ \\ -2x-2=4 \\ -2x = 4+2 \\ -2x=6 \\ 2x=-6 \\ x=-6/2 \\ x=-3$

$\dfrac{16^{x+1}}{8^{2x+2}}=16\\
\dfrac{2^{4x+4}}{2^{6x+6}}=2^4\\
2^{4x+4-6x-6}=2^4\\
2^{-2x-2}=2^4\\
-2x-2=4\\
-2x=6\\
x=-3

A, C and E all work in the equations. In order for them to work, you must use the ordered pair in each of the three situations. Below is the work for all of the correct answers.

Ordered Pair A : (1, -1)
y < x + 1
-1 < 1 + 1
-1 < 1 (TRUE)

y < 4
-1 < 4 (TRUE)

x < 6
1 < 6 (TRUE)

Ordered Pair C : (4, 2)
y < x + 1
2 < 4 + 1
2 < 5 (TRUE)

y < 4
2 < 4 (TRUE)

x < 6
5 < 6 (TRUE)

Ordered Pair E : (4, -2)
y < x + 1
-2 < 4 + 1
-2 < 5 (TRUE)

y < 4
-2 < 4 (TRUE)

x < 6
4 < 6 (TRUE)

Solve each equation. Graph and check your solutions 4= |y|
