Answer:
16
Step-by-step explanation:
3/4 = 12/x
Since 3 × 4 = 12
[Apply the same number with the numerator and denominator]
4 × 4 = 16
x = 16
1, it intersects on the line at 1
Answer:
Closed and Bounded.
Step-by-step explanation:
Hi there!
1) Let's start by finding the values in which the function is defined. Remember that this can be rewritten:

Since every quadratic root are defined for values
0 then, this help us to understand that we need calculate what interval this Domain is:

![D=[-2,2]](https://tex.z-dn.net/?f=D%3D%5B-2%2C2%5D)
2) Graphically speaking, the domain is closed. For the values -2 and 2 are included, and bounded.
Bounded functions have all of their points contained by some circle origin centered. Check it out below.
Answer:
If nobody walked on the moon, then Neil Armstrong didn't
Step-by-step explanation:
The contrapositive flips the sign of "Neil Armstrong" and the "moon," and also switches their position, so you will switch the hypothesis and conclusion as well
