SOMEONE PLEASE HELP ME QUESTION 5 2 PARTS IN THE PICTURE!!!!!

Answer:

x ≥ 6; see below for a graph

Step-by-step explanation:

First inequality

7x -6 > 8

7x > 14 . . . . . . add 6

x > 2 . . . . . . . .divide by 7

Second inequality

3x+4 ≥ 22

3x ≥ 18 . . . . . . subtract 4

x ≥ 6 . . . . . . . . divide by 3

The values of x that will satisfy both inequalities are x ≥ 6. (All of those values are > 2.)

The solution to the inequalities is x ≥ 6.

Your graph will have a solid dot at x=6, indicating 6 is part of the solution set. It will be shaded to the right, with an arrow at the right end.

A coin toss is used to determine which team will receive the ball at the beginning of a football game.

The Cougars always choose tails in the toss.

There will total of 8 cases and in 8 cases there will be three cases in which exactly two heads will come so,

3:8

The cases = {TTT, TTH, THT, HTT, HHT, HTH, HHT, HHH}

Thus, the odds in favor of the Cougars losing the toss in exactly two of three games is 3:8 option second is correct.
