To convert a mixed number into an improper fraction<span>, multiply the whole number by the denominator and add it to the numerator. This becomes the numerator of the </span><span>improper fraction, so 3 x 2 = 6 + 5 = 11 so, your answer should be 11/2</span>
Answer:

Step-by-step explanation:
For this case we need a line parallel to the plane x z and yz. And by definition of parallel we see that the intersection between the xz and yz plane is the z axis. And we can take the following unitary vector to construct the parametric equations:

Or any factor of u but for simplicity let's take the unitary vector.
Then the parametric equations are given by:



Where the point given 
And then since we have everything we can replace like this:




Answer:
x > 10
Step-by-step explanation:
x-3 > 7
Add 3 to each side
x-3+3 > 7+3
x > 10
