The first step that justifies Anne's first step while solving the expression is the commutative law of addition.

The property that best justifies Anne’s first step is the addition property of equality. This allows you to add four on the left side of the equal sign to cancel it out. In order to be fulfill the property, what you do to one side you must do to the other so you add that same amount (4) to the right side of the equal sign.

3x-4 = 5

(3x-4) +4 = 5 + 4

3x = 9

Final Answer: Addition Property of Equality

The line's equation is written as y = (-5/2)x + (3/2) in slope-intercept form.

According to the slope-intercept form, in the equation for a straight line, y=mx+b, the slope is the quantity represented by m that is multiplied on the x, and b is the y-intercept, i.e., the point where the line crosses the vertical y-axis.

To put the equation 5x + 2y = 3 in slope-intercept form, you need to rearrange the equation to have the form y = mx + b, where m is the slope and b is the y-intercept.

To do this, you can start by isolating the y term on one side of the equation:

5x + 2y = 3

2y = -5x + 3

y = (-5/2)x + (3/2)

In this configuration, the line's slope is -5/2, and its y-intercept is 3/2. Therefore, the equation of the line in slope-intercept form is y = (-5/2)x + (3/2).

An asymptote calculator is a tool that can be used to find the asymptotes of a given function.

Generally,  An asymptote is a straight line that a curve approaches, but never touches, as it extends indefinitely in one direction or another. There are three types of asymptotes: horizontal, vertical, and oblique.

To use an asymptote calculator, you would typically enter the equation of the function for which you want to find the asymptotes. The calculator will then analyze the equation and determine the type and location of the asymptotes, if any. Some asymptote calculators may also provide a visual representation of the function and its asymptotes, using a graph.

Answer:

[tex] \sf \: b) \: x = - 8[/tex]

Step-by-step explanation:

Given equation,

→ 4(2x + 1) = 6x - 12

Now the value of x will be,

→ 4(2x + 1) = 6x - 12

→ 8x + 4 = 6x - 12

→ 8x - 6x = -12 - 4

→ 2x = -16

→ x = -16/2

→ [ x = -8 ]

Hence, the value of x is -8.

This equation expresses x as a function of y, meaning y is the input and x is the output. This inverse equation can be used to solve for x when given a value of y

x = (y - 1) / 16

In order to find the inverse of a given equation, we need to switch the x and y values and solve for the new x. To do this, we start by subtracting 1 from both sides of the equation to isolate the y variable. Then, we divide both sides of the equation by 16 to find the inverse equation, x = (y - 1) / 16. This equation expresses x as a function of y, meaning y is the input and x is the output. This inverse equation can be used to solve for x when given a value of y

Answer: -6

Step-by-step explanation: To determine the largest integer value of x in the solution of the inequality 2x+6<-4, we first need to isolate x on one side of the inequality. We can do this by subtracting 6 from both sides of the inequality, which gives us 2x<-10. Next, we can divide both sides of the inequality by 2, which gives us x<-5. Since the inequality has a strict inequality symbol, we can conclude that the largest integer value of x that satisfies the inequality is -6.

Answer:

m = -1/4

Step-by-step explanation:

The slope is rise/run or (y2 - y1) / (x2 - x1)

We see the y decrease by 2 and the x increase by 8, so the slope is

-2/8 = -1/4

Answer:

Slope = -1/4

Step-by-step explanation:

Now we have to,

→ find the needed slope.

Formula we use,

→ Slope(m) = (y2 - y1)/(x2 - x1)

Then the slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (1 - 3)/(-1 -(-9))

→ m = -2/(-1 + 9)

→ m = -2/8

→ [ m = -1/4 ]

Hence, the slope is -1/4.

The factored form of 3x² + 14x + 8 is (3x + 4)(x + 2).

Factor is a number that can be divided evenly into another number. Factors are used in mathematics to simplify equations, calculate percentages, and solve problems. Factors can also be used to identify the greatest common factor (GCF) between two or more numbers. Factors can also be used to find the least common multiple (LCM) of two or more numbers.

This is the product of the two binomials (3x + 4) and (x + 2),which are the factors of the equation.

The process of factoring an equation involves breaking it down into its component parts,

which in this case are 3x² + 14x + 8. The factors of this equation are determined by first finding the greatest common factor (GCF) of the terms, which in this case is 3x + 4.

Then, the GCF is divided by each of the terms to determine the other factor. For example, 3x² / 3x + 4 =x + 2.

When the two factors are multiplied together, the result is the original equation.

b) The measure of angle BAC is given as follows: 78.4º.

The length of AB, from the sketch of the triangle given by the image at the end of the answer, is obtained using the law of cosines, as follows:

x² = a² + b² - 2abcos(C).

The parameters from the triangle are given as follows:

a = 8, b = 15, C = 70º.

Hence the length of AB is given as follows:

x² = 8² + 15² - 2 x 8 x 15 x cos(70º)

x² = 207

x = square root of 207

x = 14.387.

The measure of angle BAC is obtained using the law of sines, as follows:

sin(x)/15 = sin(70º)/14.387

sin(x) = 15 x sin(70º)/14.387

When I. there is a lot of scatter around the regression line, b1 is higher.

A statistical measure that identifies the link or co-relationship between two variables. explains the relationship between an independent variable and a dependent variable. The scatter of data points around the regression line plays a key role in estimating the slope's uncertainty in regression analysis. The data points are more dispersed and the estimation of the slope is less accurate when there is a lot of scatter. Because the estimation of the slope is based on the data points, it is less accurate when there is greater scatter in the data points.

Given

When I. there is a lot of scatter around the regression line, b1 is higher.

I am higher. The uncertainty surrounding the slope estimate, b1, increases with the amount of scatter around the regression line. The calculated slope is less dependable when there is a lot of scatter than when there is very little scatter.

When there is a large amount of scatter around the regression line, the uncertainty associated with the slope estimate, b1, is higher. This is due to the fact that the estimate of the slope depends on the data points, and when there is a lot of scatter, the data points are more dispersed, making the estimate of the slope less accurate.
