Since it’s a straight line, there is no slope. So this is a zero slope line.
Answer:
5-9i
Step-by-step explanation:
If you add the 4 and 1 you get 5, and if you add -7i and -2i since they are both negative, they stay negative, so you get -9i. So the answer is 5-9i.
19. (X+5)-3
20. 2a

23. 1/2n-15
In order to calculate the volume of a cylinder, we can use the following formula:

Where r is the base radius and h is the height.
If the circumference is 8, we have:

Now, calculating the volume, we have:

So the correct option is the second one.
