Answer:

t > 4

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

-6*t-3-(-2*t-19)<0

Step by step solution :

STEP  1

:  Pulling out like terms

Pull out like factors :

-4t + 16  =   -4 • (t - 4)

Equation at the end of step 1:

STEP 2:

Divide both sides by  -4

Remember to flip the inequality sign:

Solve Basic Inequality :

Add  4  to both sides

T > 4

If X=3+√8, find X square + 1/x square<br>​
irina1246 [14]

Given :-

  • x = 3 + √8

To find :-

  • x² + 1/x²

Solution :-

<u>According</u><u> to</u><u> Question</u><u>,</u>

  • x = 3 + √8
  • 1/x = 1/3-√8
  • 1/x = 1(3+√8)/(3+√8)(3-√8)
  • 1/x = 3+√8/3²-(√8)²
  • 1/x = 3+√8/9-8
  • 1/x = 3 + √8

<u>So </u><u> </u><u>that</u><u> </u><u>,</u>

  • x² + 1/x²
  • (x + 1/x)² - 2
  • ( 3+√8+3-√8)²-2
  • 9² - 2
  • 81 - 2
  • 79

Reagan will use a random number generator 1,200 times. Each result will be a digit from 1 to 6. Which statement best predicts ho
Stolb23 [73]

The answer is B.

The only reason it will be 200 is because the numbers 1,2,3,4,5,and 6 are all an option so the probability of 5 is 1/6 and if you multiply 1/6 by 1,200 you will get 200. Hope this helped!
