Answer:
B. -7
Step-by-step explanation:
Formula to find slope is (y2-y1) / (x2-x1)
Here we have 4 points to choose from, but we only need 2. I will use the first 2 points.
The y2 is 7, the y1 is 14, the x2 is 3, the x1 is 2.
Substitute these numbers into the formula.
(7-14) / (3-2)
^ This is basically -7/1, or -7.
Find the slope of the line through (3, - 4) and (5, 4) .
does the point (2, 5) lie on the line y = 3x-1
The solution is Yes
The point P ( 2 , 5 ) lies on the equation of line y = 3x - 1
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
y = 3x - 1 be equation (1)
Let the point be represented as P
The coordinates of P is = P ( 2 , 5 )
Substituting the values of x and y in the equation , we get
y = 3x - 1
when x = 2 and y = 5 , we get
5 = 3 ( 2 ) - 1
5 = 6 - 1
5 = 5
Therefore , the solution is true
Hence , the point P ( 2 , 5 ) lies on the equation of line

if u see a snake what do u do?
A. run away from it
B. run towards it
C. make loud noise
D. throw stuff at the snake
run towards it and throw stuff at it
Answer: A. run away from it
The African black mamba is the fastest moving land snake at 16-20 km/h. A person—regardless of how scared they are—could easily escape and outpace that snake with no problem. In reality, there's no need to run at all. The snake won't attack you unless you provoke it (i.e., don't do what option B, C, or D suggests), and snakes are probably more scared of us than we are of them. If I could add an option, I'd add: E. Leave it alone or keep still. If it moves towards you, slowly back off, and if it moves again, keep still, and then move slowly. The snake will eventually back off unless you do something to agitate it.

The slope between (8, 10) and (14, -5) will be:
[tex]m=-\frac{5}{2}[/tex]Step-by-step explanation:
Given the points
(8, 10)(14, -5)Finding the slope between (8, 10) and (14, -5)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(8,\:10\right),\:\left(x_2,\:y_2\right)=\left(14,\:-5\right)[/tex]
[tex]m=\frac{-5-10}{14-8}[/tex]
[tex]m=-\frac{5}{2}[/tex]
Therefore, the slope between (8, 10) and (14, -5) will be:
[tex]m=-\frac{5}{2}[/tex]What is the range of the following numbers?

15. Find the coordinates of D, the midpoint of AB.
16. Find the length of the median CD.
17. Find the coordinates of the centroid. Label this point as G.
Answer:
Step-by-step explanation:
15) point D=(3,1)
for AB we can see that there is an exact triangle of 2 and 5
so AD = [tex]\sqrt{2^{2} +5^{2} }[/tex] = [tex]\sqrt{29}[/tex] and 2(AD) = AB
AB = 2*[tex]\sqrt{29}[/tex] ( this is an exact answer, leave it with the square root)
16) find CD length we know the points at each end so use the distance formula P1=(-3,4) P2=(3,1)
Dist. = [tex]\sqrt{(3-(-3))^{2} +(1-4)^{2} }[/tex]
Dist. =[tex]\sqrt{45}[/tex] = [tex]\sqrt{9*5}[/tex] = 3[tex]\sqrt{5}[/tex] ( exact answer leave the square root )
CD = 3[tex]\sqrt{5}[/tex]
17) 1/3 of the way along CD from D towards C is where the centroid is.. I just happen to know that from doing this too often. :/
so that mean [tex]\frac{1}{3}[/tex] * [tex]3\sqrt{5}[/tex] is the distance from D to the centroid or [tex]\sqrt{5}[/tex]
also b/c I happen to know.. :/ c = [tex]\sqrt{1^{2}+ 2^{2} }[/tex] = [tex]\sqrt{5}[/tex] off the top of my head I can see that the point (1,2) is our centroid for this object.. they made it really easy ... okay.. relatively easy. .:D
Centroid = (1,2)

What is the value of x if AABC is equilateral?
Answer:
x= 2
Step-by-step explanation:
Given that,
AB = 7.5x
BC = 6x+3
AC = 10x-5
ΔABC is an equilateral triangle.For an equilateral triangle, all sides are equal. ATQ,
AC = BC = AB
10x-5 = 6x+3
Taking like terms together
10x-6x = 5+3
4x = 8
x = 2
Hence, the value of x is equal to 2.

Answer:
50 degrees
Step-by-step explanation:
Since the two lines are parallel, we know that the other angle above angle 1 is also 130, because corresponding angles are congruent. Next, since we know that it sits on a line, we know that angle 1 and 130 make a linear pair, or add up to 180 degrees. 180-130= angle 1. So angle 1 is 50 degrees. Sorry if the explanation is a bit funky.

Im not sure about 2 but i think its welsh corgis
3. (Im also not sure about this one, so dont take my word for it if my answer doesnt seem right) I think the heaviest dog is the welsh corgi bc i added all the weights together for the welsh corgis.
Step-by-step explanation:
According to the table the median of Welsh Corgi is 27.3kg whereas the Welsh Corgi has the maximum variation in weights.
What is the median?The median is the center most value of the data.
What is mean absolute deviation?It is the distance of value from the average mean.
How to answer?1) When we see table we can easily find that the median of Welsh Corgi is 27.3 kg and median tells us about the center level of all the weights.
2)Welsh Corgi has the greater variation in weights because its range is higher than Cocker Spaniel.
3) No, because average weight of both the type of dogs is equal.

problem:
what number needs to be added to 7 and 9 so that the ratio of the first number to the second becomes 4:5?
Step-by-step explanation:
Let the number be x.
Now after adding 7 and 9 and taking the ratios of first and second the ratio becomes 4:5.
According to the given condition,
x+7 / x+9 = 4 / 5
5 (x+7) = 4 (x+9)
Cross multiplying both sides , we get
5x + 35 = 4x + 36
x = 1
The number obtained is 1.
The number that is added to 7 and 9 and when taken ratio gives 4:5

Liana hikes slowly away from her campsite for 30 minutes. Then she rests for 10 minutes,
Finally she hikes back to her campsite at a faster pace, reaching it in 20 minutes.
Which graph could represent Liana's distance from the campsite and time?
Answer:
The answer would be A
Step-by-step explanation:
The Y axis represents the distance Liana traveled from 0 (campsite). the X axis represents the amount of time.
Liana travels away from the campsite for 30 minutes (slope), and then she stops completely for 10 minutes (no Y axis moments). She then returns back to camp faster (minutes)
Every other answer is incorrect as they maintain a single block from the graph, and each block is counted as 5 minutes. The only answer that has that 10 minute wait is answer A
The correct graph of this situation is showing in Graph 2.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Liana hikes slowly away from her campsite for 30 minutes. Then she rests for 10 minutes,
And, Finally she hikes back to her campsite at a faster pace, reaching it in 20 minutes.
Now,
Let time is showing on x - axis.
And, Distance from campsite in on y - axis.
Hence, In graph 2;
Liana hikes slowly away from her campsite for 30 minutes. Then she rests for 10 minutes, And, Finally she hikes back to her campsite at a faster pace, reaching it in 20 minutes.
