Answer:
x ≈ 0.693
Step-by-step explanation:
Using the rule of logarithms
log ⇔ n log x and lne = 1
Given
2 = 4 ( divide both sides by 2 )
= 2 ( take the ln of both sides )
ln = ln2, that is
x lne = ln2, thus
x = ln2 ≈ 0.693 ( to 3 dec. places )
Use distribution:
6x-2-3x +4
Then combine like terms:
3x + 2
Equivalent expression: 3x+2
I think it's B, though I'm not sure.
Answer:
(–∞, –3)
Step-by-step explanation:
The function is a quadratic function of order 2 and positive coefficient.
This is in the form of the function , but it is displaced 3 units to the left of the x axis and two units up in the y axis. type of functions are decreasing from -∞ to its vertex and then they are increasing from the vertex to infinity.
Observe in the attached graph that this function has its vertex in the point (-3, 2) and is decreasing from -∞ to x = -3. Then it is increasing until ∞. Therefore the correct option is:
(-∞, -3)
