How do i solve this inequality? -2|3m|+3<-51

9966 [12]

Answer:

m >9 or m < -9

Step-by-step explanation:

-2|3m|+3<-51

Subtract 3 from each side

-2|3m|+3-3<-51-3

-2|3m|<-54

Divide each side by -2, remembering to flip the inequality

-2|3m|/ -2>-54/-2

|3m|> 27

To get rid of the absolute values, we separate into two inequalities, one as written and one negative, remembering to flip the inequality

3m >27 or 3m <-27

Divide by 3 on each side

3m/3 >27/3 or 3m/3 <-27/3

m >9 or m < -9

Triangle ABC has side lengths a= 24, b= 40, and c= 55. What is the measure of angle C? 83.6° 116.2° 23.0° 40.7°

Harlamova29_29 [7]

<h3>Answer: 116.2°</h3>

Work Shown:

$c^2 = a^2 + b^2 - 2ab\cos(C)\\\\55^2 = 24^2 + 40^2 - 2*24*40\cos(C)\\\\3025 = 576 + 1600 - 1920\cos(C)\\\\3025 = 2176 - 1920\cos(C)\\\\3025 - 2176 = -1920\cos(C)\\\\849 = -1920\cos(C)\\\\-1920\cos(C) = 849\\\\\cos(C) = (849)/(-1920)\\\\\cos(C) \approx -0.4421875\\\\C \approx \cos^{-1}(-0.4421875)\\\\C \approx 116.243535748231^{\circ}\\\\C \approx 116.2^{\circ}\\\\$

The first equation is one of the three variations for the Law of Cosines.

What is the solution to this equation? 6(x-4)+7=-5

EleoNora [17]

Answer:

x = 2

Step-by-step explanation:

6(x-4) + 7 = -5

6(x-4) + 7 - 7 = -5 - 7

6(x-4) = -12

6(x-4)/6 = -12/6

x - 4 = -2

x - 4 + 4 = -2 + 4

x = 2
