Answer:
C
Step-by-step explanation:
Vertical asymptotes are always in the form x = ?
If you look at the dotted line, it lands on 2. Because it's a vertical line, the asymptote is going to be x = 2
3x² -x+4=0
We can use quadratic formula
a=3, b= -1, c=4
![x= \frac{-b+/- \sqrt{b^{2}-4ac} }{2a} \\ \\ x= \frac{1+/- \sqrt{1-4*3*4} }{2*3} \\ \\ x = \frac{1+/- \sqrt{-47} }{6} This equation does not have real roots, it has only 2 imaginary roots.](https://tex.z-dn.net/?f=x%3D%20%20%5Cfrac%7B-b%2B%2F-%20%5Csqrt%7Bb%5E%7B2%7D-4ac%7D%20%7D%7B2a%7D%20%20%0A%5C%5C%20%5C%5C%20x%3D%20%5Cfrac%7B1%2B%2F-%20%5Csqrt%7B1-4%2A3%2A4%7D%20%7D%7B2%2A3%7D%20%0A%5C%5C%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B1%2B%2F-%20%5Csqrt%7B-47%7D%20%7D%7B6%7D%20%0A%0AThis%20equation%20does%20not%20have%20real%20%20roots%2C%20it%20has%20only%202%20imaginary%20roots.)
Answer:
4
Step-by-step explanation:
3x2=6
6 times what gives 24?
6x4=24
So x=4

Step-by-step explanation:
The bill = $190
Less flat fee = 25
Work done = $165
![\text{Hours worked} = \$165 \times \dfrac{\text{1 h}}{\$55} = \textbf{3.0 h}\\\\\text{The electrician was on the job for $\large \boxed{\textbf{3.0 h}}$}](https://tex.z-dn.net/?f=%5Ctext%7BHours%20worked%7D%20%3D%20%5C%24165%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B1%20h%7D%7D%7B%5C%2455%7D%20%3D%20%5Ctextbf%7B3.0%20h%7D%5C%5C%5C%5C%5Ctext%7BThe%20electrician%20was%20on%20the%20job%20for%20%24%5Clarge%20%5Cboxed%7B%5Ctextbf%7B3.0%20h%7D%7D%24%7D)
