Answer:
x > 1
General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Define</u>
-8x + 4 < -4
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4 on both sides: -8x < -8
- Divide -8 on both sides: x > 1
Here we see that any value <em>x</em> greater than 1 would work as a solution.
Try finding what x is first from the second equation. Then plug in the answer
Given:
and where .
To find:
The explicit formula for the given recursive formula.
Solution:
We know that recursive formula of an AP is:
Where, d is the common difference.
We have,
Here, d=9.
The first term of the AP is .
The explicit formula for an AP is:
Substituting and , we get
Therefore, the required explicit formula for the given sequence is .
Answer:
$0.18 per pencil.
Step-by-step explanation:
"Dollars per unit" means that you take the dollar amount and divide it by the amount of pencils, so you get 3.24/18, or .18.
