How do I graph this.

Isolate “y” in one of the equations, then substitute it in the other equation. After you find x, put it in the isolated equation and you’ll find y value.

The value of x = 1 and y = 0.

Consider the given system of equation

4x - 2y = 4  ........(1)

6x - 4y = 6 ........(2)

Solve the system algebraically,

By using the elimination method,

Multiply equation (1) by 2, and we get,

(1) ⇒ 8x - 4y = 8 ............(3)

Subtract equation (2) from (3), we get,

8x - 4y - (6x - 4y) = 8 - 6

Simplifying the above equation, we get

8x - 4y - 6x + 4y = 2

8x - 6x = 2

⇒ x = 1

Substitute x = 1 in (1) and solve for y, we get,

⇒ 4x - 2y = 4

⇒ 4 (1) - 2y = 4

⇒ 2y = 4 - 4

⇒ 2y = 0

⇒ y = 0

Therefore, the value of x = 1 and y = 0.

Answer:

-1 12⁄13

Step-by-step explanation:

-13x = 25 [Divide by -13]

x = -1 12⁄13

13 is your divisor, which will be your denominator, and the numerator is your remainder. Since 13 goes into 25 ONCE, 1 gets multiplied by 13 to get 13, then deduct that from 25 to get your remainder of 12. This is where you start putting the pieces together as a mixed number. Then attach the negative because whenever you divide a positive by a negative, you get a negative:

-25⁄13 = -1 12⁄13

I’m not sure either, but lets keep in touch because I do Acellus too, and Trigonometry. Give me a thanks so we can message

Trigonometry involves the study of angles and sides of triangles, where sine, cosine, and tangent are fundamental ratios used to solve problems. The Law of Sines and the Law of Cosines help calculate unknown lengths and angles in various types of triangles.

Trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of triangles, particularly right-angled triangles. Key concepts such as trigonometric ratios including sine, cosine, and tangent are fundamental in solving problems in trigonometry. When provided with a diagram like Figure 4.17 or Figure 5.27, one can determine the magnitudes of various components by applying these trigonometric principles.

For instance, if we know the angle and a side length adjacent to it, we can find the lengths of the unknown sides using functions such as cosine for the adjacent side or sine for the opposite side relative to the given angle. The Law of Sines and the Law of Cosines are also substantial tools in trigonometry, allowing us to calculate unknown lengths and angles in non-right triangles. Practicing these calculations with a calculator, as mentioned, helps familiarize oneself with the trigonometric functions and their inverses.

Answer: second option.

Step-by-step explanation:

By definition, a function is even when:

[tex]f(x) = f(-x)[/tex]

Then, knowing this, given the function [tex]f(x)=x^3 +5x+1[/tex] you can substitute [tex]-x[/tex] into this function:

[tex]f(-x)=(-x)^3 +5(-x)+1[/tex]

Now you need to simplify the function. Then you get:

 [tex]f(-x)=-x^3 -5x+1[/tex]

In this case, you can see that:

 [tex]f(x)\neq f(-x)[/tex]

Therefore, the function [tex]f(x)=x^3 +5x+1[/tex] is not even.

As you observed in the procedure above, the statement that best describes how to determine whether the given function is even is:

Determine is [tex](-x)^3 +5(-x)+1[/tex] is equivalent to [tex]x^3 +5x+1[/tex]

Step-by-step explanation:

Answer:

16%

Step-by-step explanation:

To solve this we are using the standard growth equation:

[tex]y=a(1+b)^x[/tex]

Were

[tex]y[/tex] is the final value after [tex]x[/tex] years

[tex]a[/tex] is the initial value

[tex]b[/tex] is the growth factor (yearly rate of appreciation in our case) in decimal form

[tex]x[/tex] is the time in years

We know from our problem that gold coin appreciated in value from $200.00 to $475.00 in 6 years, so [tex]y=475[/tex], [tex]a=200[/tex], and [tex]x=6[/tex].

Let's replace the values in our equation and solve for [tex]b[/tex]:

[tex]y=a(1+b)^x[/tex]

[tex]475=200(1+b)^6[/tex]

[tex]\frac{475}{200} =(1+b)^6[/tex]

[tex]2.375=(1+b)^6[/tex]

[tex]\sqrt[6]{2.375} =\sqrt[6]{(1+b)^6}[/tex]

[tex]1+b=\sqrt[6]{2.375}[/tex]

[tex]b=\sqrt[6]{2.375}-1[/tex]

[tex]b=0.155[/tex]

which rounds to

[tex]b=0.16[/tex]

Since our appreciation rate is in decimal form, we need to multiply it by 100% to express it as percentage:

0.16*100% = 16%

We can conclude that the yearly appreciation rate of our gold coin is approximately 16%

b(2 ×10)+(3*1)+(0×1b)+(1×100)+(4×1000)

Final answer:

The number 23.014 in expanded form is (2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001), illustrating the value of each digit according to its place value.

Explanation:

Writing the number 23.014 in expanded form means expressing each digit according to its place value. Expanded form represents a number by showing the value of each digit. For the decimal number 23.014, we look at the place value of each digit: the digit in the tens place, the ones place, the tenths place (one place after the decimal), the hundredths place (two places after the decimal), and so on.

The correct expanded form for 23.014 is:
<(2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001)

This means:

The '2' is in the tens place, so it represents 2 x 10, or 20.

The '3' is in the ones place, so it represents 3 x 1, or 3.

The '0' is in the tenths place, but since it's 0, it adds no value (0 x 0.1 = 0).

The '1' is in the hundredths place, so it represents 1 x 0.01, or 0.01.

Finally, the '4' is in the thousandths place, so it represents 4 x 0.001, or 0.004.

Therefore, 23.014 written in expanded form is (2 x 10) + (3 x 1) + (0 x 0.1) + (1 x 0.01) + (4 x 0.001).

Answer:

[tex]f'(-8)=\frac{9}{64}[/tex]

Step-by-step explanation:

Given the function

[tex]f(x)=\frac{-9}{x}[/tex]

We can rewrite it as

[tex]f(x)=-9x^{-1}[/tex]

Now we can apply the power rule

[tex]f'(x)=9x^{-2}[/tex]

Now we can rewrite it

[tex]f'(x)=\frac{9}{x^{2} }[/tex]

Now we can plug in x=-8

[tex]f'(-8)=\frac{9}{(-8)^{2} }\\f'(-8)=\frac{9}{64}[/tex]

The derivative of f(x) = -9/x at x = -8 is 9/64.

To find the derivative of f(x) = -9/x at x = -8, we can use the power rule for differentiation. The power rule states that if we have a function of the form f(x) = x^n, then the derivative of f(x) is given by f'(x) = n*x^(n-1).

In our case, the function is f(x) = -9/x. Rewriting it as f(x) = -9*x^(-1), we can apply the power rule and find that the derivative is f'(x) = (-1)*(-9)*x^(-1-1) = 9/x^2.

Substituting x = -8 into the derivative formula, we get f'(-8) = 9/(-8)^2 = 9/64.

Answer:

[tex]x\in(-\infty,\infty)[/tex]

Step-by-step explanation:

The given function is [tex]f(x)=5^x[/tex]

Domain is the set of x values for which the function is defined.

The function  [tex]f(x)=5^x[/tex] is an exponential function and for any real values of x, the function f(x) will be defined.

Therefore, we can conclude that the domain of the function is all real numbers.

In interval notation, the domain of f(x) is

[tex]x\in(-\infty,\infty)[/tex]

The domain of the function f(x) = 5^x is all real numbers.

The domain of the function f(x) = 5x is all real numbers. In exponential functions like this one, the domain is always the set of all real numbers. This means that there are no restrictions on the values that x can take. For example, you can plug in any real number into the function, such as 0, 1, -2, or 3.5, and the function will still output a valid value.

Step-by-step explanation:

We don't need to "solve" this to figure out the answer.

We need to recognize that the first equation given is that of an ellipse and the second equation given is that of a line.

A line and an ellipse in a coordinate system can have these outcomes:

1. They can intersect (touch) at 1 point

2. They can intersect at 2 points

3. Can't intersect at all

Thinking will make sense. So, the maximum number of possible solutions is 2.

Note: The number of points of intersection are the solutions as well

Answer:

f(2) = 3

Step-by-step explanation:

We are given:

f(0) = 3

and

f(n+1) = -f(n) + 5

We have to find the value of f(2). In order to find f(2) we first have to find f(1)

f(n + 1) = - f(n) + 5

Using n = 0, we get:

f(0 + 1) = - f(0) + 5

f(1) = -f(0) + 5                                                     Using the value of f(0), we get

f(1) = -3 + 5 = 2

Now using n = 1 in the function, we get:

f(1 + 1) = - f(1) + 5                                               Using the value of f(1), we get

f(2) = -2+ 5

f(2) = 3

Thus the value of f(2) will be 3
