Answer:
yes me I want to be ur bf I'm lonely
<span>f(x)=3[x-2]
So, f(5.9) = ?
f(5.9) = 3(5.9 - 2)
=3(3.9)
=11.7 = 12
Thus, the answer is 12.

According to the given data we have the following equation:
|-ax-b|=c
So, to calculate the value of x we would have to apply the following property:
absolute rule
if |uI=a, a>o, then u=a or u=-a
Therefore, considering the propert above the calculation of would be as follows:
if a<0
-2x-1=-2
-2x=-1
x=1/2
if a>0
-2x-1=2
-2x=3
x=-3/2
The value of x would be 1/2 and -3/2
