Answer:
<em>The sum of 4 consecutive odd number is 80</em>
<em>Let X be the first of these numbers</em>
<em>Then the next odd number is X+2</em>
<em>The third is X+4The fourth is X+6</em>
<em>All of these add up to 80</em>
<em>(X) + (X+2) + (X+4) + (X+6) = 80</em>
<em>Using the commutative and associative laws, let's transform this equation into</em>
<em>(X + X + X + X) + (2 + 4 + 6) = 804X + 12 = 80</em>
<em>Subtract 12 from both sides of the equation gives4X = 68</em>
<em>Divide both sides by 4 gives</em>
<em>X = 17</em>
<em>Going back to the original question:What are the 4 consecutive odd numbers: 17, 19, 21, 23Checking our answer:17 + 19 + 21 + 23 = 80 Correct!</em>
The Pattern B is the twice of the Pattern A. Then the correct option is C.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Item 11 In the table,
Pattern A uses the rule "add 5" and Pattern B uses the rule "add 10".
Pattern A 10 15 20 25 30
Pattern B 20 30 40 50 60
Then the Pattern B is the twice of the Pattern A.
Then the correct option is C.

Answer:
- 4. -3
- 5. -1/2
- 6. 1/2
- 7. 4
- 8. 0
- 9. undefined
Step-by-step explanation:
<u>Use of slope formula:</u>
4.
- m = (7 - 4)/(1 - 2) = 3/-1 = -3
5.
- m = (-2 - 0)/(3 - (-1)) = -2/4 = -1/2
6.
- m = (5 - 3)/(5 - 1) = 2/4 = 1/2
7.
- m = (3 - 0)/(3.5 - 4.25) = 3/0.75 = 4
8.
- m = (3/4 - 3/4)/(5 - 2) = 0
9.
- m = (2 - 3)/(7.5 - 7.5) = -1/0 = undefined
