The function g(x) has a greater slope and the function f(x) has a greater y-intercept
How to compare the slopes?
The function is given as:
Function f(x)
x f(x)
-1 -6
0 -3
1 0
g(x) = 4x - 5
The slope of f(x) is calculated using:
\(m = \frac{f(1) - f(0)}{1 -0}\)
This gives
\(m = \frac{0 + 3}{1 -0}\)
Evaluate
m = 3
By the general format of a linear equation, the slope of the function g(x) is:
m = 4
4 is greater than 3
Hence, the function g(x) has a greater slope
How to compare the y-intercepts?This is when x = 0
For the function f(x), we have:
f(0) = -3
For the function g(x), we have:
g(0) = 5-
-3 is greater than -5
Hence, the function f(x) has a greater y-intercept

If the width of the dining room table is w feet, and the length is 3w - 2 feet, write an
algebraic expression that represents the perimeter of the table.
Answer:
2(w)+2(3w-2), or, 8w-4Step-by-step explanation:
The formula for finding the perimeter is 2w+2L (2*width + 2*length)
So, since we know the width is "w" and the length is "3w-2", we can just substitute those into the equation.

The statement that is equivalent to |6x-3|=3 is: 6x-3=3 or 6x-3=-3
For the equation to be true, two scenarios need to be considered:
When the expression 6x-3 is positive and equals 3:
6x-3 = 3
When the expression 6x-3 is negative and equals -3:
6x-3 = -3
By solving these two equations, we can find the equivalent statement:
Solving 6x-3 = 3:
Adding 3 to both sides gives us:

what led to the development of the aviation industry
a. the development of texas’ wwII aircraft training facilities
b. the placement of the johnson space center
c. the petrochemicals industry
d. texas’ location and climate
Texas' location and climate led to the development of the aviation industry.
What is the significance of Texas in the development of the aviation industry?
The development of the aviation industry in Texas can be attributed to its favorable geographical location and climate. Texas is located in the southern part of the United States, making it a strategic location for air travel between the east and west coasts of the country. Additionally, its warm and dry climate provided ideal conditions for flight testing and training.
Reason what led to the development of the aviation industry :
Texas has a long history of aviation, with the Wright brothers conducting one of their earliest flight demonstrations in the state in 1910. The establishment of military bases during World War II and the subsequent development of aircraft training facilities in Texas further fueled the growth of the aviation industry in the state. Additionally, the placement of the Johnson Space Center in Houston helped to establish Texas as a hub for aerospace research and development. However, it is Texas' favorable location and climate that truly made it a prime location for the aviation industry. Its central location made it a strategic location for air travel and logistics, while its warm and dry climate provided ideal conditions for flight testing and training. Today, Texas remains one of the top states for aviation and aerospace industries, with major airports, aircraft manufacturers, and research institutions located throughout the state.

Step-by-step explanation:
Twice a number decreased by 2 is 14
To solve this problem, first we need to define that the number is "x".
Then, we define what twice that number is, which would be
\(2x\)We decrease that 2x by 2:
\(2x-2\)And this would be equal to 14:
\(2x-2=14\)That would be the equation that represents the problem.
To solve that equation...
We add +2 to both sides of the equation:
\(\begin{gathered} 2x-2+2=14+2 \\ 2x=16 \end{gathered}\)and we divide both sides by 2:
\(\begin{gathered} \frac{2x}{2}=\frac{16}{2} \\ x=8 \end{gathered}\)Answer:
the equation is: 2x - 2 = 14
and the value of x is: x =8

How do you find the equation of a line given two points?To find the equation of a line given two points, you can use the point-slope form of a linear equation, which is given by:
\(y-y_1=m(x-x_1)\)
Where...
"x" and "y" are the coordinates of any point on the line"x₁" and "y₁" is a point on the line"m" is the slope of the lineTo find the equation, follow these steps:
(1) - Determine the coordinates of the two points on the line. Let's call them (x₁, y₁) and (x₂, y₂).
(2) - Calculate the slope, "m," using the formula:
\(m=\dfrac{y_2-y_1}{x_2-x_1}\)
This calculates the change in y divided by the change in x between the two points.
(3) - Substitute the slope, "m," and the coordinates of one of the points (x₁, y₁) into the point-slope form equation.
(4) - Rearrange the equation to get it into slope-intercept form. Which is written as:
\(y=mx+b\)
Where...
"y" and "x" are the coordinates of any point on the line"m" is the slope of the line"b" is the y-intercept, which is the y-coordinate where the line intersects the y-axis.\(\hrulefill\)
Step (1) -
\((x_1,y_1) \rightarrow (4,5)\\\\(x_2,y_2) \rightarrow (2,1)\)
Step (2) -
\(m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\\\\\Longrightarrow m=\dfrac{1-5}{2-4} \\\\\\\\\Longrightarrow m=\dfrac{-4}{-2} \\\\\\\\\therefore \boxed{m=2}\)
Step (3) -
\(y-y_1=m(x-x_1); \ (x_1,y_1) \rightarrow (4,5) \ and \ m=2\\\\\\\\\Longrightarrow \boxed{y-5=2(x-4)}\)
Step (4) -
\(y-5=2(x-4)\\\\\\\\\Longrightarrow y-5=2x-8 \ \text{(Applied the distributive property)}\\\\\\\\\Longrightarrow y-5+5=2x-8+5\\\\\\\\\therefore \boxed{\boxed{y=2x-3}}\)
Thus, the problem is solved.

Answer:
\(\Large\boxed{\sf y=2x-3}\)
Step-by-step explanation:
The slope-intercept form of a line is of the form \(\sf y=mx+b\) where m is the slope and b is the y-intercept.
The line passes through two points :
- A(4,5)
- B(2,1)
Let's replace x and y with their values in the equation :
\(\begin{cases}\sf 5=4m+b \\\sf 1=2m+b\end{cases}\)
We get a system of two linear equations to solve.
Let's subtract the second line from the first one and solve for m :
\(\sf 5-1=4m+b-2m-b\\\iff 4=2m\\\iff m=\frac{4}{2}\\\iff \boxed{\sf m=2}\)
Now let's substitute 2 for m in the second equation :
\(\sf 1=2\times2+b\\b=1-4\\\boxed{\sf b=-3}\)
The slope-intercept form of the line is :

How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation:
y - y₁ = m(x - x₁)
Where:
x and y represent the data points.m represent the slope.First of all, we would determine the slope of the dashed line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (0 - 4)/(4 - 0)
Slope (m) = -4/4
Slope (m) = -1
At data point (0, 4) and a slope of -1, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 4 = -1(x - 0)
y = -x + 4
y ≥ -x + 4 (since the dashed line is shaded above).
For the solid line, we have:
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (3 - 0)/(8 - 6)
Slope (m) = 3/2
At data point (6, 0) and a slope of 3/2, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 0 = 3/2(x - 6)
y = 3/2(x) - 9
\(y\ge \frac{3}{2} x-9\) (since the solid line is shaded above).

The radius of the base of a cylinder is expanding at a constant rate of 3 mm/min. If the height of
the cylinder is a constant 20 mm, find the rate at which the VOLUME of the cylinder is changing at the
moment when the radius of the base of the cylinder is 10 mm. Also find the rate at which the SURFACE
AREA of the cylinder is changing at this same moment.
(V = r²h, SA=2лrh+2rr²)
I’m getting 1800pi mm^3/min for volume and 360pi mm^2/min for surface area but I’m not sure if it’s correct
The rate at which the volume of the cylinder is changing is 600 mm^3/min, and the rate at which the surface area is changing is 240π mm^2/min.
To find the rate at which the volume and surface area of the cylinder are changing, we can use the given formulas for volume and surface area and differentiate them with respect to time. Let's calculate the rates at the moment when the radius of the base is 10 mm.
Given:
Radius rate of change: dr/dt = 3 mm/min
Height: h = 20 mm
Radius: r = 10 mm
Volume of the cylinder (V) = \(r^2h\)
Differentiating with respect to time (t), we have:
dV/dt = 2rh(dr/dt) + \(r^2\)(dh/dt)
Since the height of the cylinder is constant, dh/dt = 0.
Substituting the given values:
dV/dt = 2(10)(20)(3) + (10^2)(0)
dV/dt = 600 + 0
dV/dt = 600 mm^3/min
Therefore, the rate at which the volume of the cylinder is changing at the given moment is 600 mm^3/min.
Surface area of the cylinder (SA) = 2πrh + 2π\(r^2\)
Differentiating with respect to time (t), we have:
dSA/dt = 2πr(dh/dt) + 2πh(dr/dt) + 4πr(dr/dt)
Again, since the height of the cylinder is constant, dh/dt = 0.
Substituting the given values:
dSA/dt = 2π(10)(0) + 2π(20)(3) + 4π(10)(3)
dSA/dt = 0 + 120π + 120π
dSA/dt = 240π mm^2/min
Therefore, the rate at which the surface area of the cylinder is changing at the given moment is 240π mm^2/min.
