Answer:

Step-by-step explanation:

We assume your recursive formula is ...

$a_1=2\\a_n=a_{n-1}^2-2$

Using this to find a4, we get ...

$a_2=a_1^2-2=2^2-2=2\\a_3=a_2^2-2=2^2-2=2\\a_4=a_3^2-2=2^2-2=2\\\\\boxed{a_4=2}$

Please help A) x= -4 and 4 B) x=4 and 6 C) x=2 and 8 D) no solution

Neporo4naja [7]

Answer:

No solutions

Step-by-step explanation:

|-2x-10| + 4 = 2

Subtract 4 from each side

|-2x-10| + 4-4 = 2-4

|-2x-10| = -2

The absolute value is negative so there are no solutions.

Absolute values are always positive, so they cannot be negative.

Fofino [41]

4(2k - 3) + 1 = 8k - 11
8k - 12 + 1 = 8k - 11
8k - 11 = 8k - 11

So, these two equations equal to the same thing.
