Answer:
Step-by-step explanation:
To prove: The sum of a rational number and an irrational number is an irrational number.
Proof: Assume that a + b = x and that x is rational.
Then b = x – a = x + (–a).
Now, x + (–a) is rational because addition of two rational numbers is rational (Additivity property).
However, it was stated that b is an irrational number. This is a contradiction.
Therefore, the assumption that x is rational in the equation a + b = x must be incorrect, and x should be an irrational number.
Hence, the sum of a rational number and an irrational number is irrational.
Answer: 40
Step-by-step explanation:
So, we are looking for F of G of 2. So, we need to work backwards and find G(x) first.

So we know that g(-2) = -6, now we take thatt -6 and plug in into f(x)

68 is the answer
Answer:
h=14
Step-by-step explanation:
h=17+x/6
x=-18
h=17+-18/6
h=17+-3
h=17-3
h=14
