B. x=-8, y=-17.

First equate the two equations:

x = -8

so y = x-9 = -8-9 = -17

What is the area of this figure?

iVinArrow [24]

Answer: To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

ANSWER

The fifth term is 27

EXPLANATION

The explicit rule for the given sequence is

$t_n= {2}^{n} - n$

To find the fifth term, we substitute n=5 to get,

$t_5= {2}^{5} - 5$

$t_5= 32 - 5$

Simplify:

$t_5= 27$

The fifth term is 27
