Answer:

X = 6

Step-by-step explanation:

Cross Multiplication

We can go about this 1 of 2 ways we can either cross multiply or divide across the numerators and denominators. Let's cross multiply. We would 4*9 = 6x. Which would simplify down to 36 = 6x. We would then divide the 6 on each sides of the equation to get 6 = X.

Dividing Across

The other way we can go about it is by seeing what 4 had to be multiplied by to get to 6. We do this by dividing 6 by for which gets us 3/2 or 1.5. Now that we know this we would then divide 9 by 3/2 or 1.5 to get the answer of 6.

Answer:

Solution,

 $\frac{4}{x} = \frac{6}{9 } \\ or \: 6 \times x = 4 \times 9(cross \: multiplication) \\ or \: 6x = 36 \\ or \: x = \frac{36}{6} \\ x = 6$ 

hope this helps..

Good luck on your assignment...

Anestetic [448]

Use a graphing calculator to graph. Then, you can add the zero by finding where it intercepts the x- axis. Then, the asymptotes are lines that the rational function doesn't touch. Like this. The asymptotes are the Green and blue lines, the zero is at the origin.
