Question

please help me with this questions. it has parts a and b

a:

Solve the following inequality. Graph the solution set. 15 - 2x| >7 Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. There are finitely many solutions. The solution set is (Use a comma to separate answers as needed.) O B. There are infinitely many solutions. The solution set is (Type your answer in interval notation.) OC. There is no real solution.

b:

Thanks for your help.

Answer 1

(a) Given 15-221 27 When 5%-2X= 7 2x = 5-7 x = -1 Nowy 5-2x = -7 2x = 5+7 x = = 6 : 15–21 > 7 when x <-1 and a>6 Hence the correct option is o B. There are infinitely mamy infinitely many solution. The solution set is (-00,-1) U (6900). (6) Graph Graph of the solution set is 3 3 4 5 6 7 8 -8-7-6-5-4 -3 -2 -1 0 1 2 Solution set is outside the selected interval.
