Given:
The vertices of a parallelogram are P(1,2,1), Q(1,0,-1), R(2,2,0).
PQ and PR are the adjacent sides of the parallelogram.
To find:
The coordinates of vertex S.
Solution:
We know that, the diagonals of a parallelogram bisect each other.
Let the coordinates of the vertex S are (a,b,c).
In the given parallelogram PS and QR are the diagonals. It means their midpoints are same.
On comparing both sides, we get
Similarly,
And,
Therefore, the coordinates of vertex S are (2,0,-2).
Answer:
For the first question, the slope is -3.
For the second question, the point is (-6,7)
Step-by-step explanation:
In point-slope form, to identify the slope, its the number that's before the parenthesis, which in this case, its -3.
In point-slope form, to identify the points, its the number that replaces y1 and x1, which in this case, its -7 and 6. However, in point-slope form, the numbers are the opposite of what they are. For an example, in this equation, -7 is negative, buts its point would actually be positive.
We are given the formula in the questions, so all we need to do is solve.
0.25 = 75-p/p
0.25 = 75 - p
0.25p + p = 75
1.25p = 75
1.25p/1.25 = 75/1.25
p = 60
Therefore, the purchase price was $60.
Best of Luck!
Step-by-step explanation:
Hey, there !!
Let's simply work with it,...................
Here, theequation is,
cancelling square and square root we get answer is,
= (+ - 2).
It means the value of m is plus(+) minus(-) 2.
