Is it possible for two lines with negative slopes to be perpendicular? Justify your answer.
Answers
Answer:
No
Step-by-step explanation:
The slopes of perpendicular lines must always be the negative reciprocal of each other. If one slope is negative, for the other to be perpendicular to it, it must be positive, and vise versa.
Answer:
No
Step-by-step explanation:
Interesting question. Subtle.
The formula for two lines to be perpendicular is m1 * m1 = -1 That means that two lines cannot be minus -- only 1 of them can be. The reason is that if both were minus when multiplied together would give a positive result -- not minus one. For example, suppose you have
y = x + 2
y = 2x + 3.
These 2 lines will cross and they are not parallel, but neither are they perpendicular. I'm not going to solve this to find out where they cross -- that's not what you are asking.
Now suppose you have two other lines
y = - 2x + 3
y = 1/2 x + 1
These two lines should be perpendicular
-2 * 1/2 = - 1 which is the condition of perpendicular.

What is the opposite reciprocal of 0/6
Answers
Answer: The reciprocal of a number is defined as 1 divided by that number. The opposite of a number is the number with the opposite sign. Therefore, the opposite reciprocal of a number is equal to the reciprocal of the opposite of that number.
In this case, the opposite reciprocal of 0/6 is the reciprocal of the opposite of 0/6. The opposite of 0/6 is 0/-6, which is equal to -0/6. The reciprocal of -0/6 is 1/(-0/6) = -6/0.
However, division by 0 is not defined, so it is not possible to find the reciprocal of -0/6. Therefore, the opposite reciprocal of 0/6 is undefined.

if there were 36 dogs at the shelter? please help !!
Answers
Answer:
24 cats
Step-by-step explanation:
The ratio of cats to dogs is 6:9. There are 36 dogs in the shelter. Let's make the number of cats x.
6:9=x:36
You multiply 4 with 9 to get 36, so you do the same for 6.

Captain Kevin has a ship, the H. M. S. Khan. The ship is two furlongs from the dread pirate Ben and his merciless band of thieves. The Captain has probability \dfrac{3}{5} 5 3 of hitting the pirate ship. The pirate only has one good eye, so he hits the Captain's ship with probability \dfrac{1}{5} 5 1 . If both fire their cannons at the same time, what is the probability that the Captain hits the pirate ship, but the pirate misses?
Answers
Probability that the Captain does NOT hit the pirate's ship × Probability that the pirate hits the Captain's ship = (2/5) × (1/5) = (2/25) = 0.08
What is probability?Probability theory, a subfield of mathematics, gauges the likelihood of an occurrence or a claim being true.
The probability that the pirate hits the Captain's ship, but the Captain misses
= 2/25) = 0.08
P(C) = (3/5) is the likelihood that the captain will strike the pirate ship.
P(C') = 1 - (3/5) = (2/5) is the probability that the captain will miss the pirate ship.
P(p) = (1/5) is the likelihood that the pirate will sink the captain's vessel.
P(p') = 1 - (1/5) = (4/5) is the probability that the pirate will miss the captain's ship.
The likelihood that the pirate will hit the captain's ship while the captain misses is increased if they both fire their cannons at the same moment.
P(C' n p) is he needed probability.
P(C' n p) = P(C') P since the two events are independent of one another (p) The likelihood that the pirate will sink the captain's vessel but that the capain will miss = (Chance that the Captain misses the pirate's ship) (Chance that the pirate hits the Captain's ship) = (2/5) × (1/5) = (2/25) = 0.08

Find an equation for the line that passes through the points (-5, 2) and (3, 4)
Answers
Step-by-step explanation:
1. Find the slope first using y2 - y1/ x2 - x1. This should look like 4 -2/ 3 - (-5), which can also be written as 4 - 2/ 3 + 5.
2. Simplify the fraction. This should look like 2/8, which can also be written as 1/4 once you divide it by 2.
3. Use the point-slope formula to find the y-intercept of the equation now. The formula is y2 - y1 = m (x2 - x1). Input either (-5, 2) or (3,4) into the equation. I'll use (3,4) as an example. After inputting that point, the equation would be y - 4 = 1/4 (x - 3).
4. Simplify this equation by distributing the 1/4 into the parentheses first. Once done, the equation will be y - 4 = 1/4x - 0.75.
5. Add 4 on both sides of the equation to get y by itself. After that the equation will be y = 1/4x + 3.25.
what is an equation of the line that passes through point (-6,-5) and is parallel to the line x + 5y=25
Answers
Answer:
y = -1/5x - 31/5
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is x + 5y = 25.
First, let's put this in standard form of y = mx + b.
x + 5y = 25
Subtract x from both sides.
5y = -x + 25
Divide each term by 5.
y = -1/5x + 5
This line's slope is -1/5. A line parallel to this one will also have a slope of -1/5.
Plug this value (-1/5) into your standard point-slope equation of y = mx + b.
y = -1/5x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-6, -5). Plug in the x and y values into the x and y of the standard equation.
-5 = -1/5(-6) + b
To find b, multiply the slope and the input of x (-6)
-5 = 6/5 + b
Now, subtract 6/5 from both sides to isolate b.
-5 - 6/5 = b
-25/5 - 6/5 = b
-31/5 = b
Plug this into your standard equation.
y = -1/5x - 31/5
This equation is parallel to your given equation (y = -1/5x + 5) and contains point (-6, -5)

Which is the algebraic sequence of 1,4,7,10
Answers
The algebraic sequence of 1,4,7,10 is aₙ = 3n - 2
How to determine the explicit formula of the sequence?From the question, we have the following sequence that can be used in our computation:
1,4,7,10
In the above sequence, we can see that 3 is added to the previous term to get the current term
Using the above as a guide,
So, we have the following representation
aₙ = aₙ₋₁ + 3
Also, we have
a = 1 i.e. the first term
d = 3 i.e he common difference
When represented explicitly, we have
aₙ = a + (n - 1) * d
So, we have
aₙ = 1 + (n - 1) * 3
Evaluate the products
aₙ = 3n - 2
Hence, the explicit formula is aₙ = 3n - 2

The measure of angle TQW from the given figure is 25°.
What are perpendicular lines?A perpendicular is a straight line that makes an angle of 90° with another line. 90° is also called a right angle and is marked by a little square between two perpendicular lines as shown in the figure. Here, the two lines intersect at a right angle, and hence, are said to be perpendicular to each other.
Given that, QT⊥PQR at Q, QW⊥QS at Q, and m∠SQP=25°.
From the given figure, m∠SQP+m∠SQT=90° -------(I)
m∠TQW+m∠SQT=90° -------(II)
Here, equation (I)=(II), we get
m∠SQP+m∠SQT=m∠TQW+m∠SQT
m∠SQP=m∠TQW
25°=m∠TQW
Therefore, the measure of angle TQW from the given figure is 25°.
