First, simplify the equation.
8x - 2x - 2 = 7x + 8
Now subtract 8 on both sides to get rid of the one on the right side.
8x - 2x - 10 = 7x
Solve the left side.
6x - 10 = 7x
Subtract 6x from both sides.
-20 = x
Therefore, x = -20.
Answer by JKismyhusbandbae: a^n = 4n + 1
Explanation: So the regular formula for sequence is:
an = a1 + d (n – 1)
a1 = the first term.
d = common difference
n = term number
So in the formula form it would look like this: an: 5 - 4(n-1)
Then I like to solve it as if it were a linear equation in the end you get: a^n = 4n + 1

Answer:
$0.42
Step-by-step explanation:
Look at the function definition to see which part applies when x = 0.4. It will be the first part, which is defined for 0 < x < 1. That part tells you the postage for 0.4 oz is $0.42.
