Look for common factors in the denominators and numerators. Evaluate a fractional integer to verify if this one passes as a prime number. A assertion having two equal sides and an equal sign in the middle is called an equation in mathematics. The normal form of a linear function is an x + b = 0. The general form of a linear equation with two variables is an x + b y + c = 0. (or something similar). Inequalities can be categorized as identities or conditional equations. An identity holds true no matter what value is given to the variables.

given

point slope form = (y - y1 ) = m( x - x1 )

points are = (2,15) and (-4,9)

m = y2 - y1 / x2 - x1

Answer:

The area of a rectangle with length 4 cm and width 6 cm is 24 square cm. To find the area of a semi-circle, we use the formula for the area of a circle and divide by 2. The formula for the area of a circle is πr^2, where r is the radius. The radius of the semi-circle is half the width of the rectangle, so r = 6/2 = 3 cm. Thus, the area of the semi-circle is π(3^2) = 9π square cm.

The total area of the figure would be the sum of the area of the rectangle and the semi-circle, so the answer would be 24 + 9π square cm.

The equation, fine is $5*86 = 430so 430-430 = 0, Lin's account balance is much above zero (0), so she won't be charged $5.95 each day.

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

There are 12 elements in the original set, and each of the three smaller sets has different elements. To find the number of subsets that contain at least one element in common with each of the three sets, we need to count the number of subsets that contain at least one element from each set. To do this, we can consider each set separately and multiply the number of subsets that contain at least one element from each set.

2425÷ 45 can be solved by using long division. The first step is to divide the first number (2425) by the divisor (45). The result, 54, is the first number in the answer.

What does math's long division mean?

The mathematical operation of breaking up huge numbers into several smaller groups or sections is known as long division. The number we divide by is known as the divisor, and the number we divide into smaller groups is known as the dividend. A problem can be handled by breaking it down into smaller, more manageable parts.

Next, subtract 54 x 45 (2430) from 2425, which leaves a remainder of -5.

To continue long division, we bring down the next number in the dividend (2425), which is a 5. Next, divide the remainder (-5) by the divisor (45). The result, -1/9, is the second number in the answer.

Finally, subtract -1/9 x 45 (-5) from the remainder (-5), which leaves a remainder of 0. The answer is 54 1/9.

The statement 'Based on her electric bills from last year, Mrs. smith expects she will be paying $75/month this year' is not an example of descriptive statistics.

Descriptive statistics is a branch of statistics that are used to characterize the features of a sample by using quantitative techniques.  

Descriptive statistics can help to provide simple descriptions of the observations by using measures of Central Tendency like mean, variance, median, charts, etc...  

Data with one variable are described using univariate descriptive statistics. On the other hand, data with several variables are described using bivariate and multivariate descriptive statistics.  

The two categories of descriptive statistics are Measures of central tendency and measures of dispersion, which are used to summarize the characteristics of grouped and ungrouped data.  

Measures of central tendency are Mean, Median, and Mode, where Measures of Dispersion are Range, Variance, Standard Deviation, Mean Deviation, etc.

Here we have

Based on her electric bills from last year, Mrs. smith expects she will be paying $75/month this year.

The above statement is a prediction according to previous data but it will not represent any sample data or any other data.  

Therefore,

Let x be the number of fruit pies sold by Mr. Sanchez's class, and y be the number of bottles of fruit juice sold by Mr. Kelly's class.

(a) We can set up a system of equations to model the problem:

x + y = 53   (total number of items sold)

1.45x + 1.25y = 70.85   (total amount earned)

To solve this system using substitution, we can rearrange the first equation to solve for one variable in terms of the other:

x + y = 53

x = 53 - y

Then substitute x = 53 - y into the second equation:

1.45x + 1.25y = 70.85

1.45(53 - y) + 1.25y = 70.85

76.85 - 1.45y + 1.25y = 70.85

0.2y = 6

y = 30

Substituting y = 30 into the equation x + y = 53 gives:

x + y = 53

x + 30 = 53

x = 23

So Mr. Sanchez's class sold 23 fruit pies and Mr. Kelly's class sold 30 bottles of fruit juice.

(b) To find out which class earned more money, we can calculate the total amount earned by each class:

Mr. Sanchez's class: 1.45 x 23 = $33.35

Mr. Kelly's class: 1.25 x 30 = $37.50

Mr. Kelly's class earned more money.

(c) The amount by which Mr. Kelly's class earned more than Mr. Sanchez's class is:

$37.50 - $33.35 = $4.15

Step-by-step explanation:

A and B would move the functional graph unchanged 6 units up and down.

but that is clearly not what happened.

so, A and B are out.

h(x) is instead f(x) shifted 6 units to the left.

that means the functional value h(x) is the same as f(x') just 6 units "earlier". that means x = x' - 6 or x' = x + 6.

therefore,

h(x) = f(x + 6) = sqrt(x + 6)

The explicit rule for the sequence is f(n) = a(3)^n-1

From the question, we have the following parameters that can be used in our computation:

a_(n)=a_(n-1)*3

The above definitions imply that we simply multiply the current from by 3 to get the next term

This means that the function is a geometric function with the following parameters

Common ratio, r = 3

So, the function is

Step-by-step explanation:

To find the volume of this solid, we will use the method of cylindrical shells. We will integrate the cross-sectional area of a cylinder, given by πr^2, over the height of the solid. The height of the solid is given by the difference between the upper and lower bounds of the region, which are y = x^2 and y = 0, respectively. The radius of each cylindrical shell is given by the distance of the cross-sectional circle from the y-axis, which is x.

So, the volume of the solid is given by the integral:

V = ∫[0, 1] π * x^2 dx

Using the antiderivative of π * x^2, which is π * x^3 / 3, we can find the definite integral:

V = (π * x^3)/3 from 0 to 1

Evaluating the definite integral and simplifying, we get:

V = π/3 units^3

So, the volume of the solid is π/3 units^3.

Let's assume the values we need to find are x, y whose product and sum are known.

Write the given data in the form of equations.

By using basic substitution, you will get an expression from which you can find the values easily.

If you aren't sure whether the results arrived are accurate or not cross-check the results obtained in the equations framed with input data.

Sum of two numbers = 24

Let's consider the numbers we need to find as x and y

To solve the problem x.y = 44

x+y = 24

y=24-x

Replace the value of y in the equation x.y=44. It's not necessarily y if you want you can interchange with the value of x too as x and y are interchangeable. . (24-x)=44

On solving the equation we get two numbers as 2 and 22

That's it the two numbers whose product is 44 and the sum is 24 are 2, 22. so you should be able to do the same with your question hope that helps!
