(3,4) and (2,-1) as a fraction
The slope of the line that passes through (3,4) and (2,-1) is 5/1 as a fraction
How to calculate the slope of the line?From the question, the points are given as
(3,4) and (2,-1)
Rewrite the above points properly
So, we have the following ordered pairs
(x, y) = (3,4) and (2,-1)
The slope of the line is then calculated using the following slope equation
Slope = (y₂ - y₁)/(x₂ - x₁)
Where
(x, y) = (3,4) and (2,-1)
Substitute the known values in the above equation
So, we have the following equation
Slope = (-1 - 4)/(2 - 3)
Evaluate the difference in the above equation
So, we have the following representation
Slope = -5/-1
Lastly, we evaluate the quotient
So, we have
Slope = 5
The solution is to be in fraction form
So, we have
Slope = 5/1
Hence, the slope of the line is 5/1

The length and width of a rectangle are consecutive integers. The perimeter of the rectangle is 54 centimeters. Find the length and width of the rectangle.
Thank you!
Answer:
length = 13 cm and width = 14 cm
Step-by-step explanation:
let n be the length then n + 1 is the width
the perimeter (P) of a rectangle is calculated as
P 2(l + w) ← l is length and w is width
given P = 54 , then
2(n + n + 1) = 54 ( divide both sides by 2 )
2n + 1 = 27 ( subtract 1 from both sides )
2n = 26 ( divide both sides by 2 )
n = 13
n + 1 = 13 + 1 = 14
length = 13 cm and width = 14 cm
Find the nth term of this quadratic sequence

The nth term of this quadratic sequence 3, 8, 15, 24, 35, … is 2n
What is Sequence?An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant.
Confirm if the sequence is quadratic and this is done by finding the second difference
Sequence = 3, 8, 15, 24, 35, …
1st difference = 5, 7, 9, 11
2nd difference = 2, 2, 2
Divide the second difference by 2, and let the value be a

A new soup recipe contains 33\%33%33, percent less sodium per serving than the old soup recipe. The old soup recipe contained xxx milligrams of sodium per serving.
Which of the following expressions could represent the amount of sodium per serving, in milligrams, in the new soup recipe?
The expression that represents the amount of sodium per serving in the new soup is 0.67x milligrams.
How to find the expression that could represent the amount of sodium in the new soup?The new soup recipe contains 33%, percent less sodium per serving than the old soup recipe. The old soup recipe contained x milligrams of sodium per serving.
The expression that can be used to represent the amount of sodium per serving in milligrams in the new soup can be computed as follows;
Old soup amount of sodium = x milligram
The new soup contains 33% less sodium per serving than the old soup recipe.
Therefore,
amount of sodium per serving in the new soup = x - 33% of x
amount of sodium per serving in the new soup = x - 33 / 100 x
amount of sodium per serving in the new soup = x - 0.33x
Therefore,
amount of sodium per serving in the new soup = x(1 - 0.33)
amount of sodium per serving in the new soup = x(0.67)

An equation with only one variable is referred to as a linear equation in one variable. It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value. One such linear equation in one variable is 9x + 78 = 18.Step 1 - Write the equation.
3/a + 2 - 6a/a² - 4 = 1/a - 2
Step 2 - rewrite the equation.
3/a + 2 - 6a/a² - 4 = 1/a - 2
Step 3 - Take the LCM.
3(a- 2) - ( a + 2 )/a² - 2² = 6a/a²-4

Answer:
j = 0.4
Step-by-step explanation:

To answer this question, you should combine like terms:
Like terms are two or more terms that share the same variable.
J is the variable in this question so add 0.9j to both sides of the equation to get j on one side:
-0.1j + 0.8 = 0.76
Now subtract 0.8 from both sides to isolate j on one side of the equation:
-0.1j = -0.04
Divide both sides by -0.1 to isolate j and your answer should be:

A rectangular storage container without a lid is to have a volume of 10 m3. The length of its base is twice the width. Material for the base costs $20 per square meter. Material for the sides costs $12 per square meter. Find the cost (in dollars) of materials for the least expensive such container. (round your answer to the nearest cent. ).
The cost of materials for the least expensive such container is $327.081 .
In the question ,
it is given that
the volume of the container = 10 m³ .
let the width of the container = x
so , the length of the container = 2x
So , base area = 2x*x = 2x²
cost for base = $20
cost for the sides = $12
Since the volume is 10 m³
Volume = base area * height
10 = 2x² * h
h = 10/2x²
h = 5/x²
The cost of making the container
cost of base = 2x² * (20) = 40x²
cost of sides = [2*2x*(5/x²) + 2*x*(5/x²)](12)
= 360/x
the total cost of the container [tex]=[/tex] cost of base [tex]+[/tex] cost of sides
= 40x² + 360/x
= 40( x² + 9/x)
to get the minimum cost , we differentiate with respect to x and equate to 0
= 40 ( 2x - 9/x²)
2x - 9/x² = 0
2x³ = 9
x³ = 9/2
x³ = 4.5
x = 1.651
Substituting x in the cost equation ,
we get
Cost = 40x² + 360/x
= 40(1.651)² + 360/(1.651)
= 109.032 + 218.049
= 327.081
Therefore , The cost of materials for the least expensive such container is $327.081 .

For a line segment A ([tex]x_{1} , y_{1}[/tex]) and B ([tex]x_{2} , y_{2}[/tex]) getting divided by point C (x , y) in ratio m : n the formula is given as
x = [tex]\frac{mx_{2} + nx_{1} }{m + n}[/tex] y = [tex]\frac{my_{2} + ny_{1} }{m + n}[/tex]
Now in the question it is given that C from point A is twice the distance from point B which means ratio of A:B IS 2:1
A = (1 , 3)
B = (7 , 6)
by applying the formula
x = (2*7 + 1*1) / 2+1
x = 15/3
x = 5
y = (2*6 + 1*3) / 2+1
y = 15/3
y = 5
Therefore the coordinates of C will be (5 , 5)

Box 1 = 8
Box 2 = 2
If he earned $64 in 8 hours then dividing by 64 by 8 will tell us how much he earned in 1 hour. That gives $8
Using that we can then divide the number of dollars by the amount he receives in 1 hour to see how many hours it was.
So $16 / $8 per hour gives 2 hours
[tex]\frac{\sqrt{15} }{\sqrt[2]{3} }[/tex]
Step-by-step explanation:
both roots are square roots.
if we write the 2 or leave the base of the root blank, it both means square root.
so, we have
sqrt(15) / sqrt(3)
we can combine them into
sqrt(15/3) = sqrt(5) = 2.236067977...
Which pair of triangles can be used to show that the slope of line a is the same anywhere along the line?.
The pair of triangles that can be used to show that the slope of line a is same everywhere is upper half triangles
What is called a triangle?A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees
What is the geometry formula for a triangle?The total area that is bounded by a triangle's three sides is referred to as the triangle's area. In essence, it is equal to 1/2 of the height times the base, or A = 1/2 b h.
The pair of triangles in choice C (shown in the figure below) demonstrates that line a has a constant slope throughout.
Let's investigate:
Rise/run = slope
Regarding the initial lower triangle:
Rise = 3.5
Run = 4.5
Slope = 3.5/4.5 ≈ 0.8
For the upper second traingle:
Rise = 4
Run = 5
Slope = 4/5 = 0.8
As a result, it demonstrates that the graph's line's slope is constant throughout.
The pair of triangles that can be used to show that the slope of line a is same everywhere is upper half triangles

a) The bearing of Wellington from Gisborne is 232°
b) The bearing of Wellington from Auckland is 175.37°
How to solve bearing problems?We are given that AW = 410 km and GW = 400 km.
a) AG is a transversal intersecting two parallel lines N₁A and N₂B and ∠N₁AG = 115°.
Thus;
∠AGN₂ = 180 − 115 = 65°
since the sum of the interior angles on the same sides of the transversal intersecting two parallel lines are supplementary.
Thus;
∠N₂GW = 65 + 63 = 128°.
The reflex angle;
∠N₂GWW = 360 − 128° = 232°
b) In △AGW, we can say that by the sine rule;
(sin∠WAG)/WG = (sin∠AGW)/AG
Plugging in the relevant values;
(sin∠WAG)/400 = (sin∠63°)/410
Solving for ∠WAG gives; ∠WAG = 60.37°
Then;
∠N₁AW = 115 + 60.37
∠N₁AW = 175.37°
