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.
To find the answer, we need to see by how much 20 changed to 30.
20 (1.5) = 30
So that means that
9 (1.5) = 13.5
Answer:
Mean: 3.1
Median: 3
Mode: 2.25 appears 3 times
Range: 5 - 1.5 = 3.5
Answer:
about 66%
Step-by-step explanation:
I tested this with the number 50.
50 x 50% = 25
25 x 300% = 75
50 / 75 = 2 / 3 = 66%
To prove:
75 x 66% ≈ 50
Equal because the parallel lines :)
