-7n=63
n=-9 is your final answer. Hope it help!
The answer is A,

. This is because when plugging in -2 for x, the expression will look like this:

. To make the exponent positive, you have to flip it into a fraction. Then it will be

. Lastly, you simplify the denominator into 81.
The pattern is *2 +3 *2 +3 *2 +3 .... 1 *2 = 2 , 2+3 = 5 , 5 *2 = 10, 10 +3 = 13, 13*2 = ?...
Answer:
1
Step-by-step explanation:
One. For example, if we chose 5 as the number, then the multiplicative inverse would be 1/5. Multiplying 5 by 1/5 results in one (1).
