Answer:
Yes, lines CD & AB are perpendicular
Step-by-step explanation:
AB slope: y = -12/8x + 7
CD slope: y = 6/9x - 6
Once the slopes are simplified:
AB: -3/2
CD: 2/3
Hope this helps!
Answer:
-5/18
Step-by-step explanation:
-1 2/3 is equal to -5/3 and if you follow the keep change flip rule, keep -5/3 change the division sign to multiply and then flip the fraction (6/1 to 1/6) and then multiply.
-5/3 * 1/6 = -5/18

<u><em>To solve this question, we need to write the questions algebraically. Let's look at the problem first: The sum of a number 8, and twice the number x is equal to 28.</em></u>
<u>Algebraic form:</u>
8 + 2x = 28
<u><em>Lets solve this!</em></u>
<u><em></em></u>
8 + 2x = 28 (Algebraic Form)
2x = 28 - 8 (Subtract 8 from both sides)
2x = 20 (Divide by 2)
<u><em>x = 10</em></u> (Answer)
<u><em>ANSWER:</em></u>
