Step-by-step explanation:
<h2>
Hello!</h2>
The answer is: True.
<h2>Why?</h2>
A counterexample is a way that we can prove that something is not true about a mathematical equation or expression, it's also considered as an exception to a rule.
So:

Then, evaluating we have:

Hence, we can see that the equation is not fulfilled, so, 45° is a counterexample for
and the answer is true.
Have a nice day!
Answer:
5 bars
Step-by-step explanation:
Y+6=-1/2(x-6) or simplified to y=-1/2x-3
Answer:
no solution
Step-by-step explanation:
5 + 2(3 + 2x) = x + 3(x + 1) ← distribute parenthesis on both sides
5 + 6 + 4x = x + 3x + 3 , simplify both sides
11 + 4x = 4x + 3 ( subtract 11 from both sides )
4x = 4x - 8 ( subtract 4x from both sides )
0 = - 8 ← false statement
This indicates the equation has no solution
