Answer:
B. -2
Step-by-step explanation:
To find a slope of a line, you have to identify x and y variables:
(4, 3) => (x1, y1) (2, 7) => (x2, y2).We use the formula;
m = ∆y/∆x
= (y2 - y1)/(x2 - x1)
m is slopeSubstitute the values into the formula above.
m = (7 - 3)/(2-4)
= 4/-2
= -2
Therefore, the slope of the line is passing through points (4,3) and (2,
7) is -2.

Give me the slope for the following points (9, 10)
and (7,2)
The answer is
m = 4
Have a great day!!!
Answer:
4 is the slope
Step-by-step explanation:
We know this by using the slop formula, which is y2-y1/x2-x1
We just plug in the points that we know and solve from there,

What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
The triangle △JKL is given in the represented graph, which vertices are as follows :
J (-9, 2)
K (-4, 2)
L (-6, 4)
The image of △JKL after a reflection over the line y = x will be triangle △J'K'L' that vertices are as follows :
K' (2,-4)
L' (4,-6)
J' (2,-9)
Hence, the required graph of the image of △JKL after a reflection over the line y=x has been attached below.

A man is cycling in a place where wind is blowing. He travels 12 km against the direction of the blowing wind. In doing so, he took the same time while going 28 km in the direction of the wind. Find the speed of the wind. ( Hint - When the man is cycling in the direction of the wind, wind speed is added to his speed; otherwise it is subtracted.)
Answer:
The speed of the wind is 4.8 km/hr
Step-by-step explanation:
The parameters of the motion of the man are;
The distance the man travels in the given time while moving against the wind = 12 km
The distance the man travels in the giving time while going with the wind = 28 km
From search online for of a similar question, we have;
The speed with which the man is cycling = 12 km/hr
Let. 't', represent the time the travels each distance, let 'w', represent the speed of the wind and let 'v' represent the speed of the man, we have;
Time, t = Distance, d/(Velocity, v)
The resultant speed of the man when he travels against the wing = v - w
The resultant speed of the man when he goes in the the wing = v + w
Therefore, we have;
12/(v - w) = 28/(v + w)
12·v + 12·w = 28·v - 28·w
12·w + 28·w = 28·v - 12·v = 16·v
40·w = 16·v
∴ w = (16/40) × v = (2/5) × v
The speed with which the man is cycling = 12 km/hr
∴ The speed of the wind, w = (2/5) × v = (2/5) × 12 km/hr = 4.8 km/hr
The speed of the wind = 4.8 km/hr.

What is the equation of the line that represents the horizontal asymptote of the function f(x)=25,000(1+0.025)^(x)?
Answer:
The answer is below
Step-by-step explanation:
The horizontal asymptote of a function f(x) is gotten by finding the limit as x ⇒ ∞ or x ⇒ -∞. If the limit gives you a finite value, then your asymptote is at that point.
[tex]\lim_{x \to \infty} f(x)=A\\\\or\\\\ \lim_{x \to -\infty} f(x)=A\\\\where\ A\ is\ a\ finite\ value.\\\\Given\ that \ f(x) =25000(1+0.025)^x\\\\ \lim_{x \to \infty} f(x)= \lim_{x \to \infty} [25000(1+0.025)^x]= \lim_{x \to \infty} [25000(1.025)^x]\\=25000 \lim_{x \to \infty} [(1.025)^x]=25000(\infty)=\infty\\\\ \lim_{x \to -\infty} f(x)= \lim_{x \to -\infty} [25000(1+0.025)^x]= \lim_{x \to -\infty} [25000(1.025)^x]\\=25000 \lim_{x \to -\infty} [(1.025)^x]=25000(0)=0\\\\[/tex]
[tex]Since\ \lim_{x \to -\infty} f(x)=0\ is\ a\ finite\ value,hence:\\\\Hence\ the\ horizontal\ asymtotes\ is\ at\ y=0[/tex]
Sami lights up a candle every 10 minutes. Every candle burns for exactly 40 minutes. How many candles are burning exactly 55 minutes after Sami lit up the first candle?
Answer:
4
Step-by-step explanation:
Candle is lit every 10 minutes :
Number of candles lit in 55 minutes:
Starting from 0 minute ; Numbe rod candles lit on 55 minutes = 6
1st candle burns out after 40 minutes
Second burns out after 50 minutes
Third will burn out after 60 minutes
Hence Number of candles still burning :
Number of candles lit - Number of candle burnt out
6 - 2 = 4 candles

Write the converse, inverse and contrapositive of each conditional statement, and tell if the resulting statement is True or false
2. If mA = 100, then is not a right angle.
Converse:
Inverse:
Contrapositive:
Answer:
See below.
Step-by-step explanation:
It's good to recall what these terms mean:
Conditional statement: if p then q
Converse: if q then p
Inverse: if not p then not q
Contrapositive: if not q then not p
Conditional statement:
If m<A = 100, then <A is not a right angle.
p = m<A = 100
q = <A is not a right angle
Converse:
If angle A is not a right angle, then m<A = 100.
False. An angle that is not a right angle can have many measures other than 100 degrees.
Inverse:
If the measure of <A is not 100 degrees, then <A is a right angle.
False. If an angle has a measure of other that 100 degrees, it can have many measures in addition to 90 degrees, so it is not necessarily a right angle.
Contrapositive:
If angle A is a right angle, then m<A is not 100 degrees.
True. Only a right angle has a measure of 90 degrees, so an angle with measure 100 deg cannot be a right angle.

Olivia has at most 90$ to spend on clothes she wants to buy a pair of jeans for 22$ and spend the rest on shirts that cost 8$ each what is the greatest number of shirts she can buy
Answer:the greatest number of shirts she can buy = 8
Step-by-step explanation:
Amount of money Olivia has =$90
cost of pair of jeans =$22
such that if she buys the pair of jean, Money left to buy shirts = $90-$22= $68
If 1 Shirt= $8
Number of shirts she can buy with $68 = $68/$8= 8.5= 8 1/2
Therefore the greatest number she can buy = 8 shirts.
Grace and her brother Sid want to raise money to go to band camp. Their parents have agreed to help them up to $400 by paying them $25 when one of them mows the lawn and $10 for each hour that one of them babysits their younger brother. They will have to do a combination of both chores in order to earn the money.
Select the equation that represents the number of lawns they can mow, m, and hours they can babysit, b, to earn $400.
Step-by-step explanation:
25m + 10b = 400
not enough info to solve for m or b. but that's the equation you would use.
What is the slope-intercept equation of the line below?
Answer:
D. y = 2x -3
Step-by-step explanation:
The equation of a line in slope-intercept form is
y = mx + b
We need to find m, the slope, and b, the y-intercept.
We can find those two numbers from the graph.
We look in the graph and see that the y-intercept, b, is -3.
Now we have y = mx - 3.
Now we look for the slope. Start at (0, -2). We need to go vertically and horizontally to the next point that is easy to read. We see that point (1, -1) is on a grid intersection making it easy to read, so we will use that point.
Go up 2 units. That is a rise of positive 2. Now go right 1 unit. That is a run of positive 1.
slope = rise/run = 2/1 = 2
m = 2, so now we have
y = 2x - 3
Answer: D. y = 2x -3

Step-by-step explanation:
if DB equal to 6 then look down at CE, it has the same distance as D to B so CE equal to 6.
9514 1404 393
Answer:
CE = 10
Step-by-step explanation:
Assuming BC is parallel to DE, that segment divides the sides proportionally.
CE/CA = BD/BA
CE/25 = 6/15
CE = 25(6/15) . . . . multiply by 25
CE = 10
