Given the function f(x) = 2|x + 6| – 4, fut what values of x is f(x) = 6?

-1 and -11

Step-by-step explanation:

f(x) = 2|x + 6| – 4

Let f(x) = 6 and solve for x.

2|x + 6| - 4 = 6

Add 4 to both sides.

2|x + 6| = 10

Divide both sides by 2.

|x + 6| = 5

To deal with the absolute value in the equation we follow the rule below:

To solve an absolute value equation of the form |X| = k, where X is an expression in x, and k is a non-negative number, we solve the compound equation "X = k or X = -k".

x + 6 = 5 or x + 6 = -5

Subtract 6 from both sides in both equations.

x = -1 or x = -11

I think 45

Step-by-step explanation:

120-30=90

90 pieces are gone and divide that by two for each friend

90÷2=45 so he has 45 friends?
