Answer: 146

Step-by-step explanation:

Considering the definition of a line, the equation of the line that passes through the point (0, -4) and has a slope of  is y=3x -4.

A linear equation o line can be expressed in the form y = mx + b

where

In this case, you know:

Substituting the value of the slope and the value of the point, the value of the ordinate to the origin b can be obtained:

-4= 3×0 + b

-4= 0 + b

-4= b

-4= b

Finally, the equation of the line is y= 3x -4.

To find the slope of a tangent line using a secant line, you can use the following formula:

where (x1, y1) and (x2, y2) are points on the secant line.

This formula works because the slope of a line is simply the change in y (the "rise") divided by the change in x (the "run"). When you use two points on a secant line to approximate the slope of the tangent line, the change in y (y2 - y1) represents the rise, and the change in x (x2 - x1) represents the run.

By taking the limit of this formula as x2 approaches x1, we can find the slope of the tangent line at the point where x = x1. This is known as the limit definition of the derivative.

For example, suppose we have a function f(x) and we want to find the slope of the tangent line at x = a. We can take two points on the secant line that pass through (a, f(a)) and (a + h, f(a + h)), where h is a small positive number. The slope of the secant line through these two points is (f(a + h) - f(a))/(a + h - a) = (f(a + h) - f(a))/h. As h approaches 0, this expression approaches the slope of the tangent line at x = a.

The general form of an exponential decay function is f(a) = P . (1 - r)ᵃ,  while the general function of growth function is f(a) = P . (1 + r)ᵃ.  Hence, if the factor (1 - r) is less than 1, it is a decay function, while if the factor  (1 + r) is greater than 1, it is a growth function

The general exponential decay function can be written as:

f(a) = P . (1 - r)ᵃ

Where:

P = initial quantity

f(a) = remaining quantity at time a

a = time period

r  = decay rate

(1 - r) = decay factor

On the other hand, the general exponential growth function can be written as:

f(a) = P . (1 + r)ᵃ

where:

r = growth rate

(1 + r) = growth factor

Hence, the difference between decay function and growth function is: the factor in decay faction is less than 1, while in growth function, the factor is greater than 1.

Example:

f(a) = 6 . (0.25)ᵃ

This is an exponential decay function because the factor is less than 1, that is 0.25

f(a) = 10 . (3)ᵃ

This is not an exponential decay function, but a growth function,  because the factor is greater than 1, that is 3

The required values of x in the collinear points A, B and C are -3, 1, -12 and 12

Points that lie on the same line are called collinear points.

Given that, Points A, B, and C are collinear point B is between A and C.

We will use here segment addition postulate, to solve each part.

The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation AB + BC = AC.

1) AB = x+15, BC = x+13 and AC = 22

x+15+x+13 = 22

2x = 22-28

2x = -6

x = -3

2) BC = 2x-2, AC = 3x-3 and AB = 4

3x-3-(2x-2) = 4

3x-3-2x+2 = 4

5x = 5

x = 1

3) BC = x+28, AB = 2x+28 and AC = 12

x+20+2x+28 = 12

3x+48 = 12

3x = -36

x = -12

4) BC = x-8, AB = 9 and AC = 2x-11

x-8+9 = 2x-11

x+1 = 2x-11

x = 12

Hence, the values of x are -3, 1, -12 and 12

The plant root is growing at a rate of 3.81 centimeters per month.

To find the number of centimeters that the plant root is growing per month, you need to convert the number of inches to centimeters. One inch is equal to 2.54 centimeters, so to convert from inches to centimeters, you need to multiply the number of inches by 2.54.

In this case, the plant root grows 1.5 inches per month. Multiplying this by 2.54 gives us 3.81 centimeters, which is the correct answer. Therefore, the plant root is growing at a rate of 3.81 centimeters per month.

The other answer choices are not correct because they do not give the correct number of centimeters that the plant root is growing per month.

The relationship between y and x can be equation as y = k/x, where k is a constant that does not change.

The equation y varies inversely as x means that as the value of x increases, the value of y decreases, and vice versa. To solve for y, we can use the general equation y = k/x, where k is a constant. This equation states that the value of y is directly proportional to the reciprocal of x.

1. Start by understanding that when two variables are inversely proportional, they follow the equation

y = k/x.

2. The constant, k, is a number that will remain the same throughout the equation.

3. For example, if y varies inversely as x, and

y = 2 when x = 4, then k = 8.

4. Therefore, the equation

y = k/x becomes y = 8/x.

5. To solve for y when x = 5, substitute x = 5 into the equation and solve: y = 8/5

a) The distance of the shop from motorcyclist's home is 600 meters.

b) A distance of 1200 meters by the motorcyclist in a period of 4 minutes.

Herein we find the representation of linear equation on a Cartesian plane, where the independent variable, that is, the variable in the horizontal axis, is time (t), in minutes, and the dependent variable, that is, the variable in the vertical axis, is distance from home (d), in meters.

a) How far was the shop from the motorciclist's home?

This distance is the initial distance shown in the picture, that is, the distance at time t = 0 minutes. Thus, the shop is a distance of 600 meters away from motocyclist's home.

b) How far did the motocyclist travel in the first 4 minutes after leaving the shop?

This distance can be found by subtracting the distance at t = 4 minutes by the distance at t = 0 minutes, that is:

Δd = d(4) - d(0)

Δd = 1800 m - 600 m

Δd = 1200 m

The motorcyclist has traveled a distance of 1200 meters in a period of 4 minutes.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

We have the inequality expression,

m + 1/4 < -[tex]1\frac{2}{5}[/tex]

Simplifying,

m + 1/4 < -7/5

The lender of Jessica viewed her credit score of 790 that shows lower risk and reimbursement of outstanding balances on time.

A credit card is an electronic card that enables someone to buy items in an emergency when they don't have enough cash to pay for them. This is a specific type of bank loan that must be returned with interest in the future.

The range of numbers that make up a credit score indicate how creditworthy a credit card holder is. This aids in understanding the risk and timing of credit card bill payments. The ideal credit score range is between 300 and 850, with many alternative ranges.

According to the circumstances, Jessica's credit score is 790, which is within the range of 740 to 799, which is considered to be an excellent credit score. This demonstrates that she pays the due balances on time and that there was less of a chance that she would default on the payments.

Any credit card can help you build good credit if you consistently use only a small portion of your available credit and make on-time payments.2 But some cards are designed to help you build credit.

Secured credit cards are secured by cash: You make a security deposit to the bank ($200 is usually the minimum) and get a credit card with a limit equal to that deposit. You then use the card and make payments toward your balance to show that you are a responsible borrower.

There are 460 bass fish present if a sample of 1,000 fish is collected.

We can determine how much of one quantity is in the other by comparing two amounts of the same units and finding the ratio. Ratios can be divided into two groups. One is the part-to-whole ratio, and the other is the part-to-part ratio. The link between two distinct entities or groupings is depicted by the part-to-part ratio.

Given table shows about type and number of fish,

Type of Fish              Bass      Eel       Gar

Number of Fish          92         56       52

total number of fishes = 92 + 56 + 52 = 200
