Which of the following us the solution to 6 | x-9 | > 12?

x∈ (11, +∞)

x∈ (-∞, 7)

Step-by-step explanation:

6|x-9|>12 :Split into possible cases

6(x-9)>12, x-9≥0 : solve the inequalities

x>11, x≥9

x<7, x<9 : find the intersections

x∈ (11, +∞)

x∈ (-∞, 7)

step-by-step explanation:

change of stock price/initial stock price on friday * total stock value = change of stock value

0.89/73.73 *x = 42.72

x=3539.04 = total stock value at initial stock price on friday .

total stock value at initial stock price on friday/ initial stock price on friday = number of shares

3539.04/73.73 = 48 shares

they own 48 shares of this stock
