Zielflug [23.3K]3 years ago
4 0

I don't know about the first one but for the second one:

{2}^{3x + 2}  -  {2}^{3x}  = 48 \\ \Leftrightarrow {2}^{3x}  {2}^{2}  -  {2}^{3x}  = 48 \\ \Leftrightarrow  {2}^{3x} ( 4  - 1) = 48 \\ \Leftrightarrow 3 \times  {2}^{3x}  = 48 \\ \Leftrightarrow  {2}^{3x}  = 16 \\ \Leftrightarrow  {2}^{3x}  =  {2}^{4}  \\ \Leftrightarrow 3x = 4\Leftrightarrow x =  \frac{4}{3}

Evaluate 5/6F - 3/4F = 1/4.
Crazy boy [7]
5/6F - 3/4F = 1/4
5x4/24F - 3x6/4F = 1/4
20/24F - 18/24F = 1/4
20F - 18F = 1/4x24
2F = 6
F = 6/2
F = 3

Please help me solve these problems

Will do first question of each concept only because the rest of the questions are the same concept (the same few repeat but whatever).

1. <em>Total angle = (n - 2) * 180 --> 4 * 180 = 360°</em>

<em>70 + 130 + 120 + θ = 360</em> --> 320 + θ = 360 --> θ = 40

4. Total angle =<em> (10 - 2) * 180</em> --> 8 * 180 = <em>1440</em>

<em>1440/10</em> = 144°

6. Interior: (n - 2) * 180 --> 10 * 180 = 1800

Exterior: 12 * 180 = 2160 --> 2160 - 1800 = 360

9. (n - 2) * 180 --> 3 * 180 = 540

90 + 90 + 150 + 160 + θ = 540 --> 490 + θ = 540 --> θ = 50

13. Interior: (n - 2) * 180 --> 2 * 180 = 360

Exterior: n * 180 - (n - 2) * 180 --> 180n - 180n + 360 --> 360 (always the same)

16. 7r + 4r + 8r + 5r = 360 --> 24r = 360 --> r = 15

Which of the following tables does not represent a linear relationship between x and y?
vovangra [49]

Answer:

The first one is not liner

Step-by-step explanation:

This isn't linear because the y values increase inequally. It adds 2 and then 3 instead of keeping a constant rate
