The relationship between altitude and the boiling point of a liquid is linear. At an altitude of 8500 ft, the liquid boils at 199.55 F. At an altitude of 4300 ft, the liquid boils at 206.69 F. Write an equation giving the boiling point b of the liquid, in degrees Fahrenheit, in terms of altitude a, in feet. What is the boiling point of the liquid at ft?
Answer:b = -0.0013a + 211
Step-by-step explanation:
Since the relationship is linear, we can use a linear equation. The formula in slope-intercept form is .
As the question specifies to use a for altitude and b for boiling point, change the variables equation to
b is the boiling point.
m is the slope.
a is the altitude.
c is the y-intercept.
To find the slope, we can use the equation except x is a and y is b.
The sets of information given are:
8500 ft, the liquid boils at 199.95° (This can be info set 1)
4300 ft, the liquid boils at 205.41° (This can be info set 2)
Substitute the info sets into the equation. The subscripts mean which info set to get the numbers from.
m = -0.0013
Find the y-intercept by substituting m = -0.0013 and a random info set. I will use info set 1. Isolate c, the only variable.
b = ma + c
199.95 = (-0.0013)(8500) + c <= Simplify
199.95 = -11.05 + c
199.95 + 11.05 = -11.05 + 11.05 + c <=add 11.05 on both sides to isolate c
c = 211 <= y-intercept
Put the y-intercept and slope into the equation of a line:
b = ma + c
b = -0.0013a + 211 <= This is the equation for the problem.

Which two points should the line of best fit go through to best represent the data in the scatterplot?
Given : A graph with points (1, 3), (2, 7), (3, 8), (4, 11), (5, 12), (6, 13).
To find : From Which two points the line of best fit goes through
Solution:
(3, 8) & (5, 12) will be two points
as then line points will be
( 1 , 4 ) , ( 2, 6) , ( 3 , 8 ) , ( 4, 10) , (5 . 12) & ( 6 , 14)
(1, 3) will be below ( 1 , 4 )
(2 , 7) will be above ( 2 , 6)
( 3 , 8 ) will be on line
(4 , 11 ) will be above ( 4 , 10)
( 5 , 12 ) will be on line
( 6 , 13) will be below ( 6 , 14 )
(1, 3) & ( 6 , 13) two points are below line
(2 , 7) & (4 , 11 ) two points above line
Hence points are Equally scattered above & below line
Hence (3, 8) & (5, 12) will be two points on line of best fit
Hope it helpss !!

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 be A
Let the two points be A and B
where the point A is A ( x₁ , y₁ ) = A ( 2 , 7 )
The point B ( x₂ , y₂ ) = B ( 1 , 3 )
Now , the equation of line is given by
y - y₁ = m ( x - x₁ )
The slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
m = ( 7 - 3 ) / 2 - 1 )
m = 4
The equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 7 = 4 ( x - 2 )
y - 7 = 4x - 8
y = 4x - 1
The equation of line is y = 4x - 1
So , the points which satisfies the line is A ( 2 , 7 ) and B ( 1 , 3 )

Step-by-step explanation:
1. (x² - 4x - 10) + (x² - 9x + 3)
= x² - 4x - 10 + x² - 9x + 3
= x² + x² - 4x - 9x + 3 - 10
= 2x² - 13x - 74. (3x² - x + 1) + (15 - 9x - 2x²)
= 3x² - x + 1 + 15 - 9x - 2x²
= 3x² - 2x² - x - 9x + 1 + 15
= x² - 10x + 167. (6 - 2x + 7x²) - (10x - 3 + 3x²)

Point Lis a centroid of the triangle FWD, If RL = 54 cm, what is RD?
O 81 cm
O 162 cm
O 100 cm
O 58 cm
Answer:
RD = 162 cm
Step-by-step explanation:
LD = 2 RL = 2* 54 = 108
RD = RL + LD
RD = 54 + 108
RD = 162 cm
The length of RD is 162 cm if Point L is a centroid of the triangle FWD, If RL = 54 cm option (B) is correct.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
We have:
Point L is a centroid of the triangle FWD, If RL = 54 cm
From the centroid definition:
LD = 2RL
LD = 2×54 = 108 cm
RD = RL + LD
RD = 54 + 108
RD = 162 cm
Thus, the length of RD is 162 cm if Point L is a centroid of the triangle FWD, If RL = 54 cm option (B) is correct.

What does each term in the expression 1.4n + 1.20m represent? What does the entire expression represent? Interpret the meaning of the term 1.4n. What does the coefficient 1.4 represent? Interpret the meaning of the term 1.20p. What does the coefficient 1.20 represent?
Answer: 1.4n represents the cost of n packages of pels.
1.20m represents cost of m pads.
Entire expression 1.4n + 1.20m represents total cost of n packages of pels and m pads.
Meaning of 1.4n = cost of n packages of pels.
Meaning of 1.20 m = represents cost of m pads.
where , 1.4 = Cost per package of pels
1.2 =Cost per pad of paper
Step-by-step explanation:
Given: Cost per package of pels = $1.40
Cost per pad of paper = $1.20
Number of packages of pels bought = n
Number of pads of paper bought = m
So, 1.4n represents the cost of n packages of pels.
1.20m represents cost of m pads.
Entire expression 1.4n + 1.20m represents total cost of n packages of pels and m pads.
Meaning of 1.4n = cost of n packages of pels.
Meaning of 1.20 m = represents cost of m pads.
where , 1.4 = Cost per package of pels
1.2 =Cost per pad of paper

Tina has two rectangular playpens to keep her new pet dogs. The first rectangle has a width of 6 feet and a length of x - 4 feet. The second rectangle has a width of 8 feet and a length of x + 2 feet. What is the sum of the two perimeters?
Answer:
4x+24 ft.
Step-by-step explanation:
Perimeter of first rectangular playpen mentioned: 2(6+x-4), which can be simplified to 2(x+2) = 2x + 4.
Perimeter of second playpen mentioned: 2(8+x+2), which can be simplified to 2(x+10) = 2x+20.

Is the following relation a function?
Need answer now
If you can draw a vertical line through more than one point on the curve, then it's not a function. In this case, we can draw such a line. The graph is said to have failed the vertical line test.
What this means is that some x inputs lead to more than one y outputs. A function is only possible if any x input leads to exactly one y output. The x input must be in the domain.
Answer:
It is not a function.
Step-by-step explanation:
A relation's inputs are not repeated in a function.
Since the graph fails the vertical line test, it is not a function.

A florist charges $25 for a vase plus $4.50 for each flower. The total charge for the vase and flowers is given by the function f(x) = 4.50x + 25. How will the graph change if the vase’s cost is raised to $35? if the charge per flower is lowered to $3.00?
a) The graph change if the vase’s cost is raised to $35 is the line
[tex]y=4.5x+35[/tex]
b)The charge per flower is lowered to $3.00 is the line
[tex]y=3x+25[/tex]
We have given that the function
[tex]f(x) = 4.50x + 25[/tex]
A florist charges $25
Now we have given condition the cost is raised to 35$
We use we use the slope intercept form
What is the slope intercept form?
[tex]y=mx+C[/tex]
y is function f(x) C=vase cost, and m= charge per flower
Therefore we get,
[tex]y=f(x),m=4.50 and c=25[/tex]
we have given condition C=35$
So the line will just move up to have a y-intercept at (0,35) the equation will be,
[tex]y=4.5x+35[/tex]
Therefore,
The graph change if the vase’s cost is raised to $35 is the line
[tex]y=4.5x+35[/tex]
We have given that the charge per flower is lowered to 3$
So the slope
[tex]m=3[/tex]
Here the m value is being changed so your line will just flatten out a bit and the new equation will be
[tex]y=3x+25[/tex]
The charge per flower is lowered to $3.00 is the line
[tex]y=3x+25[/tex]
