1. To get Equation B from Equation A, we add/subtract the same quantity to/from both sides.

2. Equation A is equivalent to Equation B

What is an equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign.

Here, we have

1.  We are given the equation :

2x - 1 = 5x .............(A)

To get Equation B from A, we would subtract 2x from both sides of the equation.

2x - 2x - 1 = 5x - 2x

- 1 = 3x...... (B)

Hence, to get Equation B from Equation A, we add/subtract the same quantity to/from both sides.

2. Based on the previous answer,

2x - 1 = 5x  is equal to  -1 = 3x.

Hence, both Equation A and Equation B are equivalent expressions.

Answer:

Step-by-step explanation:

Look at the input and apply the rule. For example, if the rule is "Subtract 5" and the input is 9 then you subtract 5 from 9 to get 4, and 4 is the output. Let's take a look at some examples:

Answer in standard form:  2x+y = 3

Answer in slope intercept form:   y = -2x+3

Both equations describe the same line. Select one of those formats to write to your teacher.

=======================================================

Reason:

The equation 2x+y = 9 solves to y = -2x+9; it is of the form y = mx+b

The parallel line will also have a slope of -2. Parallel lines have equal slopes, but different y intercepts.

The slope-intercept answer is of the form y = -2x+b

Plug in (x,y) = (-1,5) and solve for b.

y = -2x+b

5 = -2*(-1)+b

5 = 2+b

3 = b

b = 3

We go from y = -2x+b to y = -2x+3 which is in slope intercept form.

Adding 2x to both sides gets us 2x+y = 3 which is in standard form.

The volume of the right circular cone hat has a height of 19 feet and base diameter of 178 is calculated as: 1,575.2 ft³.

To find the volume of a right circular cone, we can use the formula:

V = (1/3) * π * r² * h

Where V is the volume, π is approximately 3.14, r is the radius of the base, and h is the height of the cone.

Given that the diameter of the base is 17.8 feet, we can divide it by 2 to find the radius, which is 8.9 feet.

Substituting these values into the formula:

V = (1/3) * π * (8.9²) * 19

V = (1/3) * 3.14 * 78.41 * 19

V = 1,575.2 ft^3

Rounded to the nearest tenth, the volume of the cone is 1,575.2 ft³

1000 is the amount of garbage that was initially dumped in the landfill before any additional garbage was added. i.e: It is the quantity of garbage on Day 0.

The initial function given in the problem is n = 2000x + 1000.

The definition of a function's initial value is its starting value, which is unaffected by any variables used in the function.

The given function is:

n = 2000x + 1000

where the amount of trash is n, and the number of days is x. We'll set the variable (x) equal to zero to obtain the starting value.

Therefore, initially:

n = 2000(0) + 1000 = 1000

This indicates that the trash had a value of 1000 at day zero.

Therefore 1000 represents the amount of trash that was originally present in the landfill before dumping any extra trash.

Here is the process. Volume is the volume of a cylinder plus the volume of a sphere.

The surface area of a cylinder without the top and bottom plus twice the surface area of a spherical constitutes the cost of the material.

C = 2πrh + 2(4πr2)

Put what you discovered for h in this formula.

Consider Cost's derivative with regard to r. After that, zero out the derivative and find r.

By using a trigonometric relation, we will see that the hypotenuse of the right triangle is:

x = 22

We want to find the value of x on the right triangle.

Notice, it is the hypotenuse of the right triangle.

We know one angle on the triangle, and also the adjacent cathetus, then we can use the trigonometric relation:

cos(a) = (adjacent cathetus)/hypotenuse

We can replace the known values to get:

cos(30°) = 11*√3/x

(√3)/2 = 11*√3/x

Now we can solve this for x.

Dividing both sides by √3 we get:

Answer:

108 degrees

Step-by-step explanation:

The sum of the measures of the interior angles of a polygon is given by the formula:

(n-2) x 180 degrees

Where n is the number of sides of the polygon. In the case of a pentagon, the number of sides is 5, so we can use the formula to find the sum of the measures of the interior angles of a pentagon:

(5-2) x 180 = 3 x 180 = 540

If we know that the pentagon is regular, meaning that all its angles have the same measure, we can use this information and the formula above to find the measure of each interior angle.

If we divide the sum of the measures of the interior angles by the number of sides, we get the measure of each interior angle of the regular pentagon.

540/5 = 108 degrees

So, the measure of each interior angle of a regular pentagon is 108 degrees

A key part to understanding ratios is that it isn't part over whole. Ratios say that there are 5 novelists Per 3 poets.

This can be rephrased to say that there are 5 novelists per 8 TOTAL people.

Multiplying the left side by 3/3 yields 15/24

The coefficient of determination (R^2) tells you the proportion of the variance in the dependent variable that is predictable from the independent variable(s).

It tells you how well the independent variable(s) are able to predict the dependent variable. An R^2 of 1 indicates a perfect fit, and an R^2 of 0 indicates that the model does not explain any of the variance in the dependent variable.

The residual plot is a graph that shows the residuals (the difference between the observed value of the dependent variable and the predicted value) on the vertical axis and the predicted value of the dependent variable on the horizontal axis.

The residual plot is used to check for patterns in the residuals, which can indicate a problem with the model. For example, if the residuals are not randomly dispersed around zero, it may indicate that the model is not a good fit for the data. The standard error of the estimate (s) is a measure of the average distance that the data points fall from the fitted line. It represents the average distance that the observed values deviate from the true values. Lower values of s indicate a better fit of the model to the data.

Overall, the R^2, residual plot and s are used to evaluate the goodness of fit of the model.

There are 5 integer values of M that satisfy the given inequality.

An integer is a whole number, which means it is a number that can be written without a fractional or decimal component. Integers include positive numbers (e.g. 1, 2, 3), negative numbers (e.g. -1, -2, -3), and zero.

They are also often represented using the symbol "Z". Integers are a subset of the set of real numbers.

If M/20 is strictly between 1/3 and 3/5, then we have the following inequalities:

1/3 < M/20 < 3/5

To solve this, we can multiply both sides of the inequality by 20 to get rid of the denominator on the left side:

6 < M < 12

This tells us that M is an integer that lies strictly between 6 and 12 (i.e., 6 < M < 12), and the integers between 6 and 12 are 7, 8, 9, 10, and 11. Therefore there are 5 integer values of M that satisfy the inequality.
