Line n and point P are shown on the coordinate plane. What is the equation of the line parallel to line n that passes through point P?
A: y= 3x-6
B: y= 3x-6
C: y= 3x+12
D: y= -3x+3
Answer:
X = -2 - y/3
Step-by-step explanation:
First you need to know the current equation, for that:
Notice that when Y = 0, X = 2.
When Y = 6, X = 0
Therefore the equation is X = [tex]2-\frac{y}{3}[/tex]
To move that to the left of the X axis (negative direction) you just have to reduce the X number:
[tex]x=-2 - \frac{y}{3}[/tex]
Parallel lines have the same slope.
The required equation is: [tex]\mathbf{y = -3x - 6}[/tex]
The points on line n are:
[tex]\mathbf{(x,y) = (4,-6)(2,0)}[/tex]
So, the slope (m1) of line n is:
[tex]\mathbf{m_1 =\frac{y_2 - y_1}{x_2 - x_1}}[/tex]
This gives
[tex]\mathbf{m_1 =\frac{0--6}{2 - 4}}[/tex]
[tex]\mathbf{m_1 =\frac{6}{-2 }}[/tex]
[tex]\mathbf{m_1 = -3}[/tex]
If the line is parallel to line n, then it has the same slope (m2) as line n.
So, we have:
[tex]\mathbf{m_2 = m_1 = -3}[/tex]
Point P is given as:
[tex]\mathbf{P = (-3,3)}[/tex]
The equation is then calculated as:
[tex]\mathbf{y = m_2(x - x_1) + y_1}[/tex]
This gives
[tex]\mathbf{y = -3(x + 3) + 3}[/tex]
[tex]\mathbf{y = -3x - 9 + 3}[/tex]
[tex]\mathbf{y = -3x - 6}[/tex]
Hence, the required equation is: [tex]\mathbf{y = -3x - 6}[/tex]

An animal researcher randomly selected 98 dogs and cats and recorded if the napped between 2:00 p.m and 2:30 p.m. The two-way table displays the data.
Suppose an animal is randomly selected. let event c = cat and let event n = nap. what is the value of P(C|N)?
a. 38/98
b. 23/51
c. 47/98
d. 23/38
Answer: D 23/38
Step-by-step explanation:
Probability helps us to know the chances of an event occurring. The correct option is D, 23/38.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The value of P(C|N) is the ratio of the number of cats taking naps between 2:00 p.m and 2:30 p.m and the total number of cats.
Therefore, the value of P(C|N) is,
P(C|N) = P(C∩N)/P(C)
P(C|N) = 23/38

Answer:
x = 12
Step-by-step explanation:
The angles are supplementary and add up to 180
(8x - 20) + (8x + 8) = 180
Combine like terms
16x - 12 = 180
add 12 to both sides
16x = 192
Divide both sides by16
x = 12
In the circle above, LM = 2 and KL = 6.
What is the measure of MN?
A) 16
B) 10
C) 4
D) 8
Answer:
C. 4
Step-by-step explanation:
We can use power of a point to solve this problem. From this, we can set up the equation:
MN^2 = LM x MK
MK would be the sum of LM and KL because of segment addition postulate. Therefore, we can say MK = 2 + 6 = 8
Now, we can substitute the values we have in the equation above:
MN^2 = 2 x 8
MN^2 = 16
MN = 4
