Answer:

C

Step-by-step explanation:

k is the slope of the line

The equation of the line is y = kx. Therefore, the special thing about k is that it is the slope of the line.

Using a slope intercept equation,

y = kx + b

where

Therefore, the y-intercept of the line y = kx is zero.

What is special about k is that it is the slope of the line y = kx.

Answer:

Option: B is the correct answer.

The equation of the new function g(x) on flipping the function f(x) over the x-axis is:

[tex]g(x)=-2^x[/tex]

Step-by-step explanation:

We are given a graph of the exponential function f(x) which is represented by:

[tex]f(x)=2^x[/tex]

We know that when a graph of a function is reflected or flipped over the x-axis then the the change that take place to the function is that f(x) is transformed to -f(x).

( Since on flipping the function over the x-axis the positive value of the function get changed to negative and the negative value of the function is changed to positive)

Hence, the equation for the new function is:

[tex]g(x)=-f(x)\\\\g(x)=-2^x[/tex]

Jase's chickens laid more eggs.

From the information given, Jase farm has 9 chickens and each laid 3 eggs, therefore the total eggs laid will be:

= 9 × 3

= 27 eggs.

On the other hand, Ednas farm has chickens which lay a total of 23 eggs. Therefore, since 27 eggs are more than 23 eggs, Jase's chickens laid more eggs.

In conclusion, Jase's chickens laid more eggs.

Step-by-step explanation:

Given : Graph of slope [tex]\frac{-3}{4}[/tex] and passes through the point (–5, 4).

To find : Which is the equation of the line.

Solution : we have given that point ( -5 ,4)

By equation of line ([tex]y-y_{1}) = m (x -x_{1})[/tex]

y - 4 =  [tex]\frac{-3}{4}[/tex]( x +5).

Final answer:

There is a family of normal probability distributions, each representing different populations or sets of data with varying mean and standard deviation values.

Explanation:

Yes, there is a family of normal probability distributions. The normal distribution is a continuous probability distribution that can take on different forms depending on the mean and standard deviation. The family of normal distributions is characterized by different mean and standard deviation values, which result in different shapes of the distribution curve.

For example, the standard normal distribution has a mean of 0 and a standard deviation of 1, and its curve is symmetrical around the mean. Other normal distributions may have different means and standard deviations, resulting in curves that are shifted or stretched.

Each normal distribution in the family represents a different population or set of data, and knowing the specific mean and standard deviation allows us to calculate probabilities and make statistical inferences.

The company which  has the least expensive cartridge is:

                       LMN office company.

LMN Office Company sells 20 printer cartridges for $240.

This means that the cost of 1 printer cartridge is:  $ 240/20=$ 12

Also, . XYZ Supplies has a box of printer cartridges for $150.

The box contains 12 cartridges.

This means that the cost of 12 cartridge is: $ 150

Hence, cost of 1 printer cartridge is: $ 150/12=$ 12.5

Hence, the company which has the least expensive cartridge is:

            LMN Office Company.

( Since, 12 < 12.5  )

The equation of a line containing the point (3, –2) and having a slope of 2, is y = 2x-8

The general equation of a line in two variables of the first degree is represented as Ax + By +C = 0, A, B ≠ 0 where A, B and C are constants which belong to real numbers. When we represent the equation geometrically, we always get a straight line.

Given that a line containing the point (3, –2) and having a slope of 2, we need to find the equation of the line,

So, the general equation of a line is y = mx+c

Where, m is the slope and c is the y-intercept.

Therefore,

y = 2x+c

Now, put x = 3 and y = -2 in the equation to find the value of c,

-2 = 3(2)+c

-2 = 6+c

c = -8

Put the value of c in the equation,

y = 2x-8

Hence, the equation of a line containing the point (3, –2) and having a slope of 2, is y = 2x-8

To express the number of miles driven, y, in terms of the number of hours driven, t, we first find the speed and then use it to formulate the equation of the line as y = 60t. However, to accurately represent the entire trip, we must include the initial 100 miles driven in 2 hours, leading to y = 60t - 20 as the final equation.

To write an equation that gives the number of miles driven, y, in terms of the number of hours driven, t, we can use the relationship between distance and travel time. Given that after two hours you had gone 100 miles and after 8 hours, you reached your destination, which is 460 miles away, we establish two points on our distance-time graph: (2, 100) and (8, 460).

Using the two points, we can find the slope of the line, which represents the speed:
Slope (speed) = (change in distance) / (change in time) = (460 - 100) miles / (8 - 2) hours = 360 miles / 6 hours = 60 miles/hour.

We can now express the equation of the line as y = mx + b, where m is the slope and b is the y-intercept. The y-intercept represents the distance at time zero, which for most driving scenarios we assume to be 0 miles. Thus, the equation becomes y = 60t. However, this equation would not accurately represent the entire trip since it doesn't account for the initial 100 miles driven in the first 2 hours.

To adjust for that, we'll introduce an offset for the initial 100 miles traveled in the first 2 hours. The y-intercept would be 100 miles less than if we had started from 0 miles at 0 hours. The corrected equation for the entire trip would be of the form y = 60t + b, where b = y - 60t and y are the miles covered in the initial 2 hours, which is 100 miles. Substituting the values, we get b = 100 - 60 x 2 which equals -20.

The final equation, accounting for the first 2 hours of travel, would therefore be: y = 60t - 20.
