There are many steps to find the coordinates of the vertices of triangle ABC.
The slope formula is y2 - y1 / x2 - x1
There would be three equation associated with this problem.
The first equation can be found by taking the x and y's from A and B
First Equation: 2 - 3 / 1 - (-1)
Answer: -.5
The second equation can be found by taking the x and y's from B and C
Second Equation: -1 - 2 / -3 - 1
Answer: 12
The third equation can be found by taking the x and y's from C and A
Third Equation: 3 - (-1) / -1 - (-3)
Answer: 2
These are not equal measurements so, it isn't right angle.
Answer:
-2a +11b
Step-by-step explanation:
3(a+2b) - 5(a-b)
we apply distributive property:
3*a + 3*2b - 5*a + 5*b
3a+ 6b -5a +5b
-2a +11b
No the don't add up to one eighty I'm pretty sure if not tell me
when "If P, then Q" is true, "if not Q, then not P¨ is also true.
So the given statement is true.
<h3>
The statement is true or false?</h3>
Let's suppose we have a conditional statement:
If P, then Q.
That is true.
The statement says that:
If not Q, then not P.
Is also true.
Now, let's go to the original conditional statement.
"If P, then Q"
This means that always that P is true, then Q must also be true. But we can have cases where P is false and Q is true. (this means that Q can't be true if P is not true).
Now, if we affirm that Q is false (or not Q is true, these are the same thing). Then we must have that P is also false (or not P is true).
So the given statement is true.
when:
If P, then Q
is true.
if not Q, then not P¨
is also true.
