What is the equation of the line passing through the points (3,1) and (6,7)
Answer:
y=2x-5
Step-by-step explanation:
You want to find the equation for a line that passes through the two points:
(3,1) and (6,7).
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
First, let's find what m is, the slope of the line...
The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.
For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:
So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (3,1), point #1, so the x and y numbers given will be called x1 and y1. Or, x1=3 and y1=1.
Also, let's call the second point you gave, (6,7), point #2, so the x and y numbers here will be called x2 and y2. Or, x2=6 and y2=7.
Now, just plug the numbers into the formula for m above, like this:
m=
7 - 1
6 - 3
or...
m=
6
3
or...
m=2
So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:
y=2x+b
Now, what about b, the y-intercept?
To find b, think about what your (x,y) points mean:
(3,1). When x of the line is 3, y of the line must be 1.
(6,7). When x of the line is 6, y of the line must be 7.
Because you said the line passes through each one of these two points, right?
Now, look at our line's equation so far: y=2x+b. b is what we want, the 2 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (3,1) and (6,7).
So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!.
You can use either (x,y) point you want..the answer will be the same:
(3,1). y=mx+b or 1=2 × 3+b, or solving for b: b=1-(2)(3). b=-5.
(6,7). y=mx+b or 7=2 × 6+b, or solving for b: b=7-(2)(6). b=-5.
See! In both cases we got the same value for b. And this completes our problem.
The equation of the line that passes through the points
(3,1) and (6,7)
is
y=2x-5
3x + 7 = -8

If M = {Prime integers between 1 and 11} and N = { factors of 12}. Find:
The members of M
The members of N
M∪N;
M∩N.
Please show working
Step-by-step explanation:
members of "M" = 2,3,5,7,11
members of "N" = 1,2,3,4,6,12
M∪N = 1,2,3,4,5,6,7,11,12
M∩N = 2,3
intersection is the overlapping numbers in the sets
union is the set with all the numbers but they cannot be duplicates
The members of "M" [tex]=[/tex] [tex]2,3,5,7,11[/tex]
The members of "N" [tex]= 1,2,3,4,6,12[/tex]
M∪N [tex]= 1,2,3,4,5,6,7,11,12[/tex]
M∩N [tex]= 2,3[/tex]
What is Prime number ?
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number.
According to questions, M = {Prime integers between [tex]1[/tex] and [tex]11[/tex]}
and N = { factors of [tex]12[/tex]}.
We have to find the members of M, the members of N, M∪N and M∩N.
M = {Prime integers between [tex]1[/tex] and [tex]11[/tex]} [tex]=[/tex][tex]2,3,5,7,11[/tex]
N = { factors of [tex]12[/tex]} [tex]= 1,2,3,4,6,12[/tex]
So, M∪N [tex]= 1,2,3,4,5,6,7,11,12[/tex]
and M∩N [tex]= 2,3[/tex]
Hence, we can conclude that
The members of "M" [tex]=[/tex] [tex]2,3,5,7,11[/tex]
The members of "N" [tex]= 1,2,3,4,6,12[/tex]
M∪N [tex]= 1,2,3,4,5,6,7,11,12[/tex]
M∩N [tex]= 2,3[/tex]

An appliance store sells microwave ovens and has many different styles to choose from. A handout from the store
contains details about brand, type (countertop or over-range), number of power settings, and color. Which of the
variables is a discrete quantitative variable?
O brand
O type
power settings
O color
Answer:
Power settings.
Step-by-step explanation:
In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.
Basically, random variables are classified into two (2) main categories and these are; continuous and discrete random variable.
A discrete random variable is a data set in which the number of possible values are either finite or countable. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.
In this scenario, an appliance store sells microwave ovens and has many different styles to choose from. A handout from the store contains details about brand, type (countertop or over-range), number of power settings, and color.
Hence, the variable which is a discrete quantitative variable is the number of power settings because its values are countable or finite, usually it ranges from 100 to 800.

Suzi starts her hike at 240 feet below sea level. When she reaches the end of the hike, she is still below sea
level at - 143 feet. What was the change in elevation from the beginning of Suzi's hike to the end of the
hike?
Answer:
383ft
Step-by-step explanation:
Given parameters:
Elevation = 240ft at the start
Elevation at the end = -143ft
Unknown:
Change in elevation:
Solution:
The change in elevation is the difference between the two hiking milestone;
change in elevation = Elevation at the start - Elevation at the end
= 240ft - (-)143ft

Juan invests $7500 at 6% interest in one year. How much money will he have if the interest were compounded A. yearly B. Daily C. why are the amounts in answers a and b different
Answer:
A) 7,950$, B) 7,963.73$, C) Since daily interest means that 6%/365 of 7500 will be added and compounded every day for the given amount of time(in this case, one year), while annual interest means that 6% of 7500 will be added and compounded yearly for the given amount of time(I'm this case, one year).
Step-by-step explanation:
Given the compound interest formula, A = P(1+r/n)^nt, where A = total amount(final amount), P = principle or amount of money deposited(starting amount), r = annual interest rate(percent interest in respect to t ; decimal = %/100), and n = conversion rate(number of times compounded per t; how much is it compounded)
t = time(time in respect to years ; how long it is compounded).
For A) A = 7500( 1 + 6%/365 ) ^ 365 = 7500(1 + 0.06/365) ^365 = 7500(1 + 0.00016438356..)^365= 7500(≈1.0001644^365) = 7500(100.01644%^365) = 7500(≈106.183%) = 7963.725 ≈ 7963.73$
For B) A = 7500( 1 + 6% ) ^ 1 = 7500(1 + 0.06) = 7500(1.06) = 7500(106%) = 7950$
C) this is because compounding something with a higher frequency leads to a different percentage (as n approaches infinity with time proportional to the annual rate, the ratio between the principle and total amount are proportional to e)

What is an equation of the line that passes through the point (2,-2) and is parallel
to the line 5x – 2y = 4?
Answer:
y=2.5x-7
Step-by-step explanation:
First, 5x - 2y = 4
=> - 2y = 4 - 5x
y = 2.5x -2
Since the line we want to know is parallel to the given one,
its slopw would be 2.5 as well
so let the line passes through the point (2,-2) be y=2.5x+a
then 2.5* 2 +a = -2 => a = -7
Final answer: y=2.5x-7
y=5/2x-7 is equation of the line that passes through the point (2,-2) and is parallel to the line 5x – 2y = 4.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Given that, a line is passing through (2,-2) and is parallel to line 5x – 2y = 4.
We need to find the equation of other line.
We need to write the equation of line in slope intercept form.
5x – 2y = 4
-2y=4-5x
2y=5x-4
y=5/2x-2
The slope of line is 5/2
Since the line we want to know is parallel to the given one,
If two lines are parallel then slope of two lines will be parallel.
So the slope of line passing through (2, -2) should be 5/2.
let the line passes through the point (2,-2) be y=5/2x+c
then 5/2(2) +c = -2
c=-2-5
c=-7
Equation of line parallel to 5x-2y=4 is y=5/2x-7
Hence y=5/2x-7 is equation of the line that passes through the point (2,-2) and is parallel to the line 5x – 2y = 4.
