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.

What is an equation in slope-intercept form for the line that passes through the points (1,-3) and (3,1)
Step-by-step explanation:
Hey there!
Note: Use double point formula for finding the eqaution which passes through two points.
Given;
The points are; (1,-3) and (3,1).
Use double point formula.
[tex](y - y1) = \frac{y2 - y1}{x2 - x2} (y - y1)[/tex]
Put all values.
[tex](y + 3) = \frac{1 + 3}{3 - 1} (x - 1)[/tex]
Simplify it.
[tex](y + 3) = \frac{4}{2} (x - 1)[/tex]
[tex]y + 3 = 2(x - 1)[/tex]
[tex]y + 3 = 2x - 2[/tex]
[tex]y = 2x - 2 - 3[/tex]
[tex]y = 2x - 5[/tex]
Therefore, the eqaution is y = 2x-5.
Alternative:
Steps:
Find slope using slope formula and use one point formula.Simplify in the form of y = mx+c form.Formula:
Slope = (y2-y1)/(x2-x1)One point formula= (y-y1)= m(x-x1)The points are; (1,-3) and (3,1).
Now;
Slope= (1- (-3))/(3-1)
= (1+3)/2
= 2
Again;
Using one-point formula.
(y+3) = 2(x-1)
y+3= 2x-2
y = 2x -5
Therefore, the equation is y = 2x-5.

Answer: Point A represents Q1, Point B represents the Median, Point C represents Q3
Step-by-step explanation:
Study the equations:
f(x) = 6x + 7
g(x) = 4x – 2
What is h(x) = f(x)g(x)?
h(x) = 24x2 – 14
h(x) = 24x2 + 40x + 14
h(x) = 24x2 + 16x – 14
h(x) = 24x2 + 12x – 14
Answer:
h(x)=24X^2+40x+14
The rectangle has length 8 cm and area 48 cm2.
The perimeter of the square is the same as the perimeter of the rectangle.
Calculate the area of the square.
Step-by-step explanation:
Given,
length of rectangle(l)= 8cm
area of rectangle(A) = 48cm2
breadth of rectangle(b) = ?
Perimeter of rectangle (P)=?
We know ,
Area of rectangle(A) = l×b
or, 48cm2 = 8cm×b
or, 48cm2 = 8bcm
or, 48cm2/8cm = b
or, 6cm = b
or, b = 6cm
therefore, b = 6cm
Perimeter of rectangle (P) = 2(l+b)
= 2(8cm+6cm)
= 2×14cm
= 28cm
therefore, Perimeter of rectangle(P) = 28cm
Now,
According to the question,
Perimeter of rectangle(P) = Perimeter of square(P)
So,
Perimeter of square(P) = 28cm
length of square(l) = ?
Area of square (A) = ?
We know,
Perimeter of square (P) = 4l
or, 28cm = 4l
or, 28cm/4 = l
or, 7cm = l
or, l = 7cm
therefore, l = 7cm
Now,
Area of square (A) = l^2
= (7cm)^2
= 7cm×7cm
= 49cm^2
therefore, area of square (A)= 49cm^2
The area of the square based on the information is 49cm².
Since the rectangle has length 8 cm and area 48 cm², the width will be:
= 48/8 = 6cm.
Therefore, the perimeter will be:
= 2(l + w)
= 2(8 + 6)
= 28cm
Therefore, the length of the square will be:
= 28/4 = 7
Area of the square will be:
= 7cm × 7cm
= 49cm²

Step-by-step explanation:
Given
The attached graph
Required
Explain what the slope represents (Missing part of the question:)
First, we'll check the slope of the graph.
Represent time in weeks with x and savings in dollar with y
So, we have the following details:
[tex](x_1,y_1) = (0,40)[/tex]
[tex](x_2,y_2) = (8,80)[/tex]
Slope (m) is then calculated as thus:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{80 - 40}{8 - 0}[/tex]
[tex]m = \frac{40}{8}[/tex]
[tex]m = 5[/tex]
The calculated slope is positive and this implies that: As the number of week increases, the Andre's savings also increases

Bradley estimated the height of a tree at 2.5 meters. Carla estimated that tree's height at 8 feet.
How could a conversion ratio be used to compare Bradley's and Carla's estimates of the tree's height when measured in feet? (1 foot = 0.305 meters)
Answer: 4.1 feet : 4 feet
Step-by-step explanation:
From the question, we are informed that Bradley estimated the height of a tree at 2.5 meters. Carla estimated that tree's height at 8 feet.
The conversion ratio be used to compare Bradley's and Carla's estimates of the tree's height when measured in feet goes thus:
Since 1 feet = 0.305 meters
2.5 meters will be = 2.5/0.305 = 8.2 feet
Therefore the conversion ratio will be:.
= 8.2 : 8
Reducing to lowest term will be
= 4.1 feet : 4 feet.
= 4.1 : 4

distance between a(3,9) b(-10,4)
Answer:
√194 i think
Step-by-step explanation:
Answer:
[tex]\boxed {d = \sqrt{194}}[/tex]
Step-by-step explanation:
Use the Distance Formula to help you find the distance between the two given points:
[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
First point: [tex](x_{1}, y_{1})[/tex]
Second point: [tex](x_{2}, y_{2})[/tex]
-Substitute the two given points onto the formula:
First point: [tex](3, 9)[/tex]
Second point: [tex](-10, 4)[/tex]
[tex]d = \sqrt{(-10 - 3)^{2} + (4 - 9)^{2}}[/tex]
-Then, you solve for the distance:
[tex]d = \sqrt{(-10 - 3)^{2} + (4 - 9)^{2}}[/tex]
[tex]d = \sqrt{(-13)^{2} + (-5)^{2}}[/tex]
[tex]d = \sqrt{169 + 25}[/tex]
[tex]\boxed {d = \sqrt{194}}[/tex] (since the number cannot be square rooted, the number will stay the same)
Therefore, the distance is [tex]\sqrt{194}[/tex].

find the value of x pls
Answer:
answer is 45 add all angle=360 it make 360/8
Answer:
x = 45
Step-by-step explanation:
The 2 interior angles of the triangle adjacent to both 3x's is
180 - 3x
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2x is an exterior angle of the triangle, thus
180 - 3x + 180 - 3x = 2x , that is
360 - 6x = 2x ( add 6x to both sides )
360 = 8x ( divide both sides by 8 )
45 = x
