Answer:

- \(\frac{2}{3}\) x

Step-by-step explanation:

Given

\(\frac{4x-8x^2}{12x-6}\) ← factorise numerator and denominator

= \(\frac{4x(1-2x)}{6(2x-1)}\) ← factor out - 1 from (1 - 2x) on numerator

= \(\frac{-4x(2x-1)}{6(2x-1)}\) ← cancel the common factor (2x - 1)

= \(\frac{-4x}{6}\) ← cancel 4 and 6 by 2

= - \(\frac{2}{3}\) x

Simplifying the expression will give us: \(\frac{4x-8x^2}{12x-6} = \frac{-2x}{3}\)

Given the expression, \(\frac{4x-8x^2}{12x-6}\), we are required to simplify the expression as follows:

Step 1: Factorize the denominator and the numerator.

\(\frac{4x-8x^2}{12x-6}\\\\=\frac{(1 - 2x)4x}{(2x - 1)6}\)

Step 2: Rewrite the fraction by factoring out -1 from the numerator.

\(=\frac{(2x - 1)-4x}{(2x - 1)6}\)

Step 3: Divide the numerator and denominator by (2x - 1) respectively.

\(=\frac{-4x}{6}\)

Step 4: Divide the numerator and denominator by 2 respectively.

\(=\frac{-2x}{3}\)

Therefore, simplifying the expression will give us: \(\frac{4x-8x^2}{12x-6} = \frac{-2x}{3}\)

Resulting function is y = -(1/5)e⁴ˣ - 4, which can be written in the form y = \(ce^{ax}\) + b as y = (-1/5)e⁴ˣ - 4.

To transform the given function y = e⁴ˣ according to the given conditions, we will perform the following steps:

1. Vertically compress With a factor of 5:
y = (1/5)e⁴ˣ

2. Reflect across the x-axis:
y = -(1/5)e⁴ˣ

3. Shift down 4 units:
y = -(1/5)e⁴ˣ - 4

So the resulting function is y = -(1/5)e⁴ˣ - 4, which can be written in the form y = ceᵃˣ + b as y = (-1/5)e⁴ˣ - 4.

a. The altitude CG = 2 × EF

b. The area of triangle ABC = 4 × ADE

Similar triangles are triangles that have the same shape, but their sizes may vary. The corresponding angles of similar triangles are equal.

The ratio of corresponding sides of similar triangles are also equal.

a. Since the scale factor = 2

scale factor = length of big triangle / length of small triangle

2 = CG/EF

CG = 2 × EF

b. area factor = scale factor²

area factor = 2² = 4

Option b is the correct answer as all the points of a scatter diagram lie on the least squares regression line, then the coefficient of determination for these variables based on these data is 1.

The coefficient of determination, denoted as R-squared (R²), measures the proportion of the variance in the dependent variable that can be explained by the independent variable(s) in a regression model. R-squared ranges from 0 to 1, where 0 indicates no relationship and 1 indicates a perfect fit.

When all the points of a scatter diagram lie on the least squares regression line, it means that the independent variable(s) perfectly predict the dependent variable. In this case, all the observed variation in the dependent variable is accounted for by the regression line, resulting in an R-squared value of 1.

Answer:y – 9. 4 less than a number. y - 4

Step-by-step explanation:

If the sum of a number and 9, divided by 4, is greater than or equal to -2, the number is -17.

A collection of two or more inequalities in one or more variables is known as a system of inequalities. When there are multiple constraints on a problem's potential solutions and a range of potential solutions are needed, systems of inequalities are used. The maximum or minimum values of a situation with multiple constraints are frequently determined using a system of linear inequalities.

It is given that,the sum of a number and 9, divided by 4, is greater than or equal to -2

Suppose the number is n,

(n+9)/4≥-2

n+9≥-8

n≥-8-9

n≥-17

Thus, if the sum of a number and 9, divided by 4, is greater than or equal to -2, the number is -17.

Answer:

Zero

Step-by-step explanation:

Let's solve the equation first.

For now, I will focus on the LHS and simplify that:

3(x + 2) = 3x + 1

3x + 6 = 3x + 1

Rearrange

3x - 3x = 1 - 6

Simplify

0x = -5

0 = -5 which isn't true

So 3(x + 2) = 3x + 1 has 0 solutions.

Answer:

The distance the players must run is \(150 m\)

Step-by-step explanation:

The distance that the players must run diagonally from one corner of the soccer field to the inverse corner can be found by using the Pythagorean hypothesis,

The Pythagorean hypothesis may be a scientific guideline that relates to the sides of a right triangle. It states that the square of the length of the hypotenuse (the longest side of the triangle) is break even with to the whole of the squares of the lengths of the other two sides.  

The length of the soccer field is 120 m long.(given)

The width of the soccer field is 90 m (given)

and width of the soccer field shape the two legs of the right triangle, and the corner-to-corner distance is the hypotenuse. Hence, we can utilize the Pythagorean theorem as takes after:

Distance = \(\sqrt{(length^{2} } + width^{2}\)

                \(= \sqrt{120^{2} + 90^{2} }\)

                = (\(\sqrt{(14400 + 8100)}\)

                = \(\sqrt{22500}\)

                 \(= 150.00 meters\)

Therefore, the distance the players must run is 150. m

The regression line is a statistical tool that can be used to analyze the relationship between two variables.

It helps identify trends in the data and can be used to make predictions about future values. It can also be used to assess the accuracy of the model and to determine the strength of the relationship between the two variables.

By examining the slope of the regression line, we can assess the direction and strength of the linear relationship between the two variables.

Additionally, the y-intercept of the regression line can provide insight into the value of the dependent variable when the independent variable is equal to zero.

The average change in Michelle's position per minute is 3.27 meters per minute.

Initial position of Michelle is -2.1 m.Final position of Michelle is -38.6 m.Time taken is 6 min and 14 sec.Time taken = 6 minutes and 14 seconds= 6 + 14/60 minutes= 6.23 minutes

Change in position= Final position - Initial position= (-38.6) - (-2.1)= -38.6 + 2.1= -36.5 metersAverage change in position per minute = Total change in position / Total time taken in minutes= -36.5 / 6.23= -5.8589 ≈ -5.86 meters per minuteWe take the magnitude of the displacement because it is the distance between the two positions. Therefore, the average change in position per minute is 5.86 meters per minute.If we consider the displacement as negative then the average change in position per minute is 3.27 meters per minute.

Answer:

Step-by-step explanation:

This is the only sequence that is using constant repetition of addition, either adding positive numbers or adding negative numbers (the same positive or negative number). This one that you answered is always adding 2 from the prior number, so -6 = -8+2, -4=-6+2, and so on.

The first one is an odd combo where you add and subtract different values different signs each time, it is not constant addition of the same number.

The second one is multiplication which is not arithmetic, so that means it is constantly being multiplied by 2 each time.
