Farmer Joe Crazyhair has 12.4 acres of land. He uses 4.52 acres of land for growing fruits and 6.15 acres of land for growing vegetables. How many acres are not being used by Mr. Crazyhair? :)

Answer:

Therefore, the solution to the equation -x + 3y = 11 is x = -34/11 and y = 29/11.

Step-by-step explanation:

The given equation is:

-x + 3y = 11

To solve this equation by elimination, we need to add or subtract one or both equations to eliminate one of the variables. In this case, we can eliminate the variable x by adding the equation with another equation that has x with the same coefficient, but opposite sign.

Let's suppose we have another equation with x, for example:

2x + 5y = 7

We can eliminate x by multiplying the first equation by 2 and the second equation by 1, so that the coefficients of x are opposite:

-2x + 6y = 22 (multiply the first equation by -2)

2x + 5y = 7 (the second equation)

Now we can add the two equations to eliminate x:

-2x + 2x + 6y + 5y = 22 + 7

Simplifying the equation, we get:

11y = 29

Dividing both sides by 11, we get:

y = 29/11

Now that we know the value of y, we can substitute it back into one of the original equations to find the value of x. Let's use the first equation:

-x + 3y = 11

Substituting y = 29/11, we get:

-x + 3(29/11) = 11

Simplifying the equation, we get:

-x + 87/11 = 11

Subtracting 87/11 from both sides, we get:

-x = 11 - 87/11

Multiplying both sides by -1, we get:

x = 87/11 - 11

Simplifying the equation, we get:

x = (87 - 121)/11

x = -34/11

It is crucial to  that any written work is original and does not involve plagiarism.Quadratic equations are mathematical expressions that involve a variable raised to the power of two

Quadratic equations are mathematical expressions that involve a variable raised to the power of two, and they are widely used in many fields of science and engineering. The general form of a quadratic equation is ax^2 + bx + c = 0, where a, b, and c are constants and x is the variable.

The reason why there are usually two solutions in quadratic equations is because of the quadratic formula, which gives the values of x that satisfy the equation. The formula is:

x = (-b ± √(b^2 - 4ac)) / 2a

The ± sign indicates that there are two possible solutions, one with a positive square root and one with a negative square root. This is because a quadratic equation typically has two x-intercepts, or roots, when graphed on a coordinate plane.

One example from real life where quadratics are utilized is in the field of physics, specifically in the study of motion. The equation for the position of an object in freefall under the influence of gravity is a quadratic equation. The equation is:

y = 1/2gt^2 + v0t + y0

where y is the position of the object at time t, g is the acceleration due to gravity, v0 is the initial velocity of the object, and y0 is the initial height of the object.

I picked this example because it illustrates how quadratic equations can be used to model real-world phenomena. In this case, the equation allows us to predict the position of a falling object at any given time. This information can be useful for engineers designing safety equipment for skydivers, for example, or for physicists studying the behavior of objects in motion.

It is important to note that while using ideas and examples from the internet or textbooks can be a helpful starting point for understanding a topic, it is crucial to ensure that any written work is original and does not involve plagiarism. Plagiarism involves using someone else's work or ideas without giving them proper credit, and it is a serious academic offense that can result in consequences such as failing an assignment, failing a course, or even being expelled from school. To avoid plagiarism, it is important to always properly cite sources and use one's own words to express ideas and information.

Answer:

Number of boys = 675

Step-by-step explanation:

Given that:

There are 5 times as many boys as girls in a school.

Number of pupils in school = 810

Let,

x be the number of girls

y be the number of boys

According to given statement;

x+y=810      Eqn 1

y = 5x         Eqn 2

Putting y=5x in the Eqn 1

x+5x=810

6x=810

Dividing both sides by 6

\(\frac{6x}{6}=\frac{810}{6}\\x=135\)

Putting x=135 in Eqn 2

y = 5(135)

y = 675

The two statements about risk and return that are true or potentially true are:

What is risk and return?

The risk connected to a particular investment and its returns are known as risk and return in financial management. High-risk investments typically produce higher financial returns, and low-risk investments typically produce lower returns. In other words, a given investment's risk and return are directly correlated.

As the risk of an investment increases, so does the potential for a higher return because there is a direct correlation between risk and return.

Also, holding stocks of companies of different sizes and from different sectors reduces investment risk in a portfolio because on diversifying the portfolio, risk also gets divided thus, giving a satisfactory return to the investor.

Hence, the above two statements are true.

Answer: As the risk of an investment increases, so does the potential for a higher return. and Holding stocks of companies of different sizes and from different sectors reduces investment risk in a portfolio.

Step-by-step explanation: Increased price fluctuation, upward or downward, increases risk and the possibility of a high return or a huge loss. When the risk, or price fluctuation, is low, so is the return potential. Diversification helps decrease the risk of a group of investments because the value of individual investments will increase or decrease at different time periods and help to lessen value fluctuation in the overall portfolio.

Answer:

To find the slope of the line tangent to the graph of the function at x = -3, we need to find the derivative of the function and evaluate it at x = -3.

First, let's find the derivative of the function y = x^4 + 2x^3 + 2x + 2:

y' = 4x^3 + 6x^2 + 2

Now, let's evaluate y' at x = -3:

y'(-3) = 4(-3)^3 + 6(-3)^2 + 2

= -108 + 54 + 2

= -52

Therefore, the slope of the line tangent to the graph of the function y = x^4 + 2x^3 + 2x + 2 at x = -3 is -52.

Answer:

(x² + 7x + 6) ÷ (x² + 2x + 1)

This should be in the form of a fraction, I just don't know how to format it that way on here.

Step-by-step explanation:

Since your denominators are equal on both fractions, you just need to subtract your numerators.

3x² + 9x + 12 - (2x² + 2x + 6)

When there is a - in front of an expression in parenthesis, you should change the sign of each term in the expression of the numerator being subtracted.

So this:

2x² + 2x + 6

Will become this:

2x² - 2x - 6

This is how it will look:

3x² + 9x + 12 - 2x² - 2x - 6

Now all you have to do is collect the like terms.

3x² and -2x² are like terms so you will add them together: 3x² + (-2x²) = 3x² - 2x² = x²

This is how your numerator should look so far:

x² + 9x + 12 - 2x - 6

Now we move on to the next like terms.

9x and -2x are like terms so we add them together: 9x + (-2x) = 9x - 2x = 7x

This is how your numerator should look so far:

x² + 7x + 12 - 6

Now we move on to the last set of like terms.

12 and -6 are like terms so we add them together: 12 + (-6) = 12 - 6 = 6

This is how your numerator should be now:

x² + 7x + 6

Now all you have to do is put your numerator on top of your denominator which is the same as in the start of your equation (x² + 2x + 1).

You are done! I hope this was clear and you understand :)
