You're almost looking at the solution. Almost.
If it only said " r = 1 ", then that would be the solution right there.
But it says " | r | = 1 ", so there's a little more to it.
'r' can be either +1 or -1 and that equation will be a true statement.
So +1 and -1 are both solutions.
A fraction is in simplest form when the numerator and denominator share no common factors.
The prime factorization of 5 is 5.
The prime factorization of 6 is 2×3.
The numerator and denominator share no common factors, thus 5/6 is already in simplest form.
The 4 reasons for the Algebra proof are respectively;

<h3>How to use algebra properties?</h3>
We want to use algebra properties to find the value of x in the expression; -5(x + 4) = 90
Statement 1; -5(x + 4) = 90
Reason 1; Given
Statement 2; -5x - 20 = 90
Reason 2; Distributive property of Algebra because we distributed -5 into the bracket terms.
Statement 3; -5x = 110
Reason 3; Addition property of equality because we added 20 to both sides to achieve that.
Statement 4; x = -22
Reason 4; Division property of equality because we divided both sides by -5 to obtain x = -22.
Thus, the 4 reasons are respectively;
Given; Distributive property; Addition Property; Division Property

A={a,b,c}, B={9,16,25}, and f={(a,9),(b,16),(a,25)}. True or false, f is a function from A to B?

Answer: False</h3>
Explanation:
The input x = a leads to multiple outputs y = 9 and y = 25 at the same time. This is due to the points (a,9) and (a,25) in the set f.
A function can only be possible when any x input leads to exactly one y output only. You'd need to get rid of either (a,9) or (a,25) to make this a function.
