1 answer:
Naya [18.7K]2 years ago
5 0

Answer:

6, 7, and 8

Step-by-step explanation:

2x/3 + 7 <u>></u> 11

Subtract 7 from both sides

2x/3 <u>></u> 4

Multiply both sides by 3

2x <u>></u> 12

Divide both sides by 2

x <u>></u> 6

6, 7, and 8 are the ones that work

Solve -2a-5&gt;3. which graph shows the solutions?<br>​
Flura [38]

Answer:

see explanation

Step-by-step explanation:

Given

- 2a - 5 > 3 ( add 5 to both sides )

- 2a > 8

Divide both sides by - 2, reversing the direction of the inequality sign as a consequence of dividing by a negative quantity

a < - 4

Since a is less than we require an open circle at - 4 on the number line.

Since less than the arrow head is pointing to the left, that is

Graph A, the top graph illustrates the solution

If the first 4 terms of a geometric sequence are {7, 21, 63, 189), then the formula for the nth term in the sequence is?
34kurt

Answer: 7 × ( 3^n - 1 )

Step-by-step explanation:

This is a geometric progression which has its nth term to be

Tn = ar^n- 1. Now from the question given, the sequence are 7, 21, 63, 189. This is an example of a finite sequence, To find the common ratio, you divide the second term by the first term. So

r = 21/7

= 3. , a = 7

Now to find the nth term put the values in the formula above.

Tn =ar^n-1

= 7(3)^n - 1)

= 7 × ( 3^n - 1 ).

Note, it is not 21^n - 1.
