Answer:
6, 4, 2, 0
Step-by-step explanation:
To find the first 4 terms, substitute n = 1, 2, 3, 4 into the n th term formula, that is
a₁ = 8 - 2(1) = 8 - 2 = 6
a₂ = 8 - 2(2) = 8 - 4 = 4
a₃ = 8 - 2(3) = 8 - 6 = 2
a₄ = 8 - 2(4) = 8 - 8 = 0
The first 4 terms are 6, 4, 2, 0
Answer:
D. 66/2
Step-by-step explanation:
If you are trying to figure out what operation to perform first, then follow PEMDAS.
<em>P: Parenthesis</em>
<em>E: Exponents</em>
<em>M: Multiplication</em>
<em>D: Division</em>
<em>A: Addition</em>
<em>S: Subtraction</em>
<em />
So first we start with what is in parenthesis. Since there are two operations within the parenthesis, we start with the division first since it comes first in PEMDAS. This is why D. 66/2 is our best answer.
C. $693.33. Just round. It helps. Round 2,080 to 2,100. Then whats 30% of 2,100? It's easy just think of 21 divided by 3, which equals 7. So, 700 and the closest answers to that is $693.33. That's just the easy way instead of doing the math out. And it is also common sense that B or D wouldn't be it. So your left with C or A. :)
Answer
6,7,-4,8 wold work becuse you cant have two of the same x's
Step-by-step explanation:
You would multiply by
.
When you rationalize the denominator, you multiply by the conjugate of the denominator. The conjugate is the same numbers and radicals, but with the sign of the radical switched.
