Answer:
7
Step-by-step explanation:
14-5 =9
9-10= -1
-1 + 8 =7
−4y + 4y + 2 = 2
<span> −4y + 4y = 2 -2
0 = 0 .
Anytime you have this format of 0 = 0, just know there are infinitely many.
Any number as a value of y can satisfy the equation.

Infinitely many
Answer:
Each one has two possibilites, so the total is 2*2*2*2 = 16

For this case we must find an expression equivalent to:

By definition of power properties we have to:

So:

We have by definition of properties of powers that:
Then, rewriting the expression:

Answer:

Answer:
Step-by-step explanation:
Tn = ar^(n-1)
a = 4, r = 8/4 = 2 for n = 15
T15 = 4 × 2^(15-1)
= 4 × 2^14
= 4 × 16384
= 65536
