AysviL [449]3 years ago
3 0

Answer:

  • 8 - 14b ≥ 27                   ⇒ subtract 8 from both sides
  • - 14b ≥ 27 -8            
  • - 14b ≥ 19                       ⇒ divide both sides by 14
  • - b ≥ 19/14                      ⇒ multiply both sides by -1
  • b ≤ - 19/14                      ⇒ multiplication by a negative changes the  

                                                   inequality sign to opposite one

b ≤ - 19/14  and the answer choices B, C and D are all correct as are less than -19/14

A. 140 is the only one incorrect

For each sequence, determine whether it appears to be arithmetic, geometric, or neither.
Art [367]

Step-by-step explanation:

1. 2, 4, 6, 8, ...

This sequence has a common difference (+ 2).  So it is arithmetic.

2. 9, 16, 25, 36, ...

This sequence has neither a common difference nor a common ratio.

3. 64, 32, 16, 8, ...

This sequence has a common ratio (× ½).  So it is geometric.

The correct answer is y < 18. Let's pretend a student forgot to flip the symbol and they mistakenly believe the solution set
snow_tiger [21]

Answer:

It is wrong

Step-by-step explanation:

y < 18

This is read as y is less than 18. If the students forgot to flip the symbol and mistakenly believe that y > 18.

y > 18

This is read as y is greater than 18.

There is a difference between the numbers greater or less than 18 .

y must have numbers less than 18 and 21 is greater than 18.

Therefore it is wrong.

But to make it true we can multiply minus with the inequality y > 18

-y > -18

This reverses the inequality sign and it becomes

y< 18

The solution which is required.
