Try to prove the hypothesis from part B that the sum of a rational and an irrational number is an irrational number.
Maurinko [17]

The next step of your proof is to subtract (a/b) from both sides.

Then you get, x = (m/n) - (a/b)

Since rationals are closed over addition, (m/n) + (-a/b) is a rational number.

Therefore, x (an irrational number) = a rational number                            <em>This is a false statement which is a contradiction. So, the assumption was incorrect.</em>

Thus, the sum of a rational and irrational number is an irrational number. QED

On 2 plays that is times 2
So all together is -4×2
A negative times a positive is negative
-4×2= -8

If f(x) = -x + 5 and g(x) = x^2, what is (g° (-1)?
ipn [44]

Answer:

(g\circ f)(-1)=36

Step-by-step explanation:

We are given the two functions:

f(x)=-x+5\text{ and } g(x)=x^2

And we want to find:

(g\circ f)(-1)

This is equivalent to:

=g(f(-1))

So, evaluating f(-1) first, we acquire:

f(-1)=-(-1)+5=6

Then by substitution:

=g(6)

So:

=(6)^2=36

Therefore:

(g\circ f)(-1)=36

Your answer is indeed correct.
