Step-by-step explanation:

We find the determinant of a matrix by the method below. If we have a matrix:

[tex]\left[\begin{array}{cc}a&b\\c&d\end{array}\right][/tex]

The determinant is [tex]ad-bc[/tex]

Now, using cramer's rule, we find x-value by the formula:

[tex]x=\frac{D_x}{D}[/tex]

Where D is the determinant of the original problem and [tex]D_x[/tex] is the determinant of the x-value matrix. How do we get those?

To get original matrix and thus D, we set up the matrix as the coefficients of x and y (s) of both the equations and to get matrix of x-value and thus [tex]D_x[/tex], we replace the x values of the matrix with the numbers in the right hand side of the 2 equations. We show this below:

To get D:

[tex]\left[\begin{array}{cc}3&4\\1&-6\end{array}\right] \\D=(3)(-6)-(1)(4)=-18-4=-22[/tex]

To get [tex]D_x[/tex]:

[tex]\left[\begin{array}{cc}12&4\\-18&-6\end{array}\right] \\D_x=(12)(-6)-(-18)(4)=0[/tex]

Putting into the formula, we get:

[tex]x=\frac{D_x}{D}=\frac{0}{-22}=0[/tex]

Thus, the value of x is 0

Your answer would be A

Step-by-step explanation:

First you gotta reduce that fraction. Then square root the 9 (which is 3) and as well as radicalize x^5, which is x^2/x

Answer:

FIRST OPTION.

Step-by-step explanation:

Given the expression [tex]\sqrt{\frac{2x^5}{18}}[/tex], you can find an equivalent expression simplifying.

The first step is to descompose 18 into its prime factors:

[tex]18=2*3*3=2*3^2[/tex]

Remember the Product of powers property, which states that:

[tex](a^m)(a^n)=a^{(m+n)}[/tex]

Then you can rewrite the expression in this form:

 [tex]\sqrt{\frac{2x^4x}{2*3^2}[/tex]

Knowing that [tex]\sqrt[n]{a^n}=a[/tex], you get the following equivalent expression:

[tex]\sqrt{\frac{2x^4x}{2*3^2}[/tex]

[tex]\frac{x^2}{3}\sqrt{\frac{2x}{2}}[/tex]

[tex]\frac{x^2\sqrt{x}}{3}[/tex]

Answer:

The answer is 225.

Step-by-step explanation:

The explanation is in the top.

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = [tex]\frac{4}{5}[/tex] and (a, b) = (9, - 1), hence

y - (- 1) = [tex]\frac{4}{5}[/tex](x - 9), that is

y + 1 = [tex]\frac{4}{5}[/tex](x - 9) ← in point- slope form

Everywhere you see x in the equation replace it with 1 like so...

3(1) + y = 5

3 + y = 5

Finish isolating y. To do this first subtract 3 to both sides (what you do on one side you must do to the other). Since 3 is being added, subtraction (the opposite of addition) will cancel 3 out (make it zero) from the left side and bring it over to the right side.

3 - 3 + y = 5 - 3

0 + y = 2

When x is 1 then y is 2

Check:

3(1) + 2 = 5

3 + 2 = 5

5 = 5

Hope this helped!

Answer:

y=2

Step-by-step explanation:

3x + y =5

3(1) + y = 5

3 + y = 5

5-3= y which is 2

Step-by-step explanation:

y = x - 2

x + y = 12

Substitute the first expression for y into the second equation.

x + (x - 2) = 12

2x - 2 = 12

2x = 14

x = 7

Now plug into either equation to find y.

y = 7 - 2

y = 5

So the solution is (7, 5).

Answer:

4  1/4

Step-by-step explanation:

Complementary angles add up to 90 degrees.

Thus if 12q - 9 and 8q + 14 are complementary,

12q - 9 + 8q + 14 = 90.

Combining like terms, we get:

20q + 5 = 90

20q = 85

Thus, q = 85/20, or 17/4, or 4  1/4

Answer:

42 and 48

Step-by-step explanation:

∵ Two angles are complementary to each other if their sum is 90°,

Given,

12q - 9 and 8q + 14 are complementary angles,

By the above statement,

12q - 9 + 8q + 14 = 90

Combine like terms,

20q + 5 = 90

Subtract both sides by 5,

20q = 85

Divide both sides by 20,

q = 4.25,

Thus, the angles are,

12(4.25) - 9 and 8(4.25) + 14

⇒ 42 and 48

Logarithm functions are the inverses of exponential function.In the given graphs the graph number 2 is plotted with the above points. Hence the option 2 is correct.

The function given in the question is,

[tex]f(x)=log_3x[/tex]

Logarithm functions are the inverses of exponential function.

To plot the graph of the given function we have to find the asymptotes;

vertical asymptote  [tex]x=0[/tex]

Find the points at [tex]x=1[/tex]

[tex]f(0)=log_3(0)[/tex]

[tex]f(0)=0[/tex]

Find the points at [tex]x=3[/tex]

[tex]f(3)=log_3(3)[/tex]

[tex]f(0)=1[/tex]

Find the points at [tex]x=9[/tex]

[tex]f(9)=log_3(9)[/tex]

[tex]f(9)=2[/tex]

Hence, the points for the given function are (1,0) (3,1) and (9,2).

In the given graphs the graph number 2 is plotted with the above points. Hence the option 2 is correct.

https://brainly.com/question/13473114

The answer is:

The first option shows the graph of the given function.

Since the given function is an exponential function, we are looking for an exponential function graph, with a function that intercepts the y-axis at y equal to 2, or the point (0,2).

So, since we are given just one exponential graph, let's find the y-axis intercept in order to assure that the correct option is the first graph.

The function is:

[tex]y=2e^{x}[/tex]

Finding the y-axis intercept, we need to make "x" equal to 0, so:

[tex]y=2e^{0}[/tex]

We need to remember that any number elevated or powered to 0 is equal to 1, so:

[tex]y=2*1=2[/tex]

We have that the function intercepts the y-axis at y equal to 2, or the point (0,2).

Finding the x-axis intercept, we need to make "y" equal to 0, so:

[tex]y=2e^{x}[/tex]

[tex]0=2e^{x}[/tex]

[tex]Ln(0)=Ln(2e^{x})[/tex]

Now, since the natural logarithm of "0" does not exist in the real numbers, we can see that there is not x-axis intercept for this function.

Hence, the first option shows the graph of the given function.

multiply the percentage of the corn by 360 degrees

15% × 360° = 54°

Answer:

54°

Step-by-step explanation:

In the given pie chart which shows variation of vegetable.

Pie chart is a circular. Complete angle of circular is 360°.

100% of pie chart is equal to 360° of central angle.

Here, we need to find the central angle of corn.

In graph, corn is only 15%

 100% of central angle = 360°

   1% of central angle [tex]=\dfrac{360^\circ}{100}[/tex]

15% of central angle  [tex]=\dfrac{360^\circ}{100}\times 15[/tex]

add 2 to both sides

4x - 2 + 2 > 6x + 8 + 2

4x > 6x + 10

Now, subtract 6x from both sides

4x -6x > 6x -6x + 10

it remains

-2x > 10

divide via by -2

x > 10/-2

x < -5

Final answer:

The cost for Mrs. Beusse to buy 100 personalized pencils is $405.00.

Explanation:

According to the chart, the cost of pencils depends on the number of pencils being purchased. For 1-20 pencils, the cost is $5.35 each. For 21-40 pencils, the cost is $4.70 each. For 41-60 pencils, the cost is $4.05 each. Since Mrs. Beusse needs to buy 100 personalized pencils, we need to determine which price range this falls into. 100 pencils falls within the range of 81-100, so the cost per pencil will be $4.05.

Therefore, the total cost for 100 personalized pencils will be $4.05 x 100 = $405.00.

The answer is:

[tex]f(3)=|x|+(-2x^{2})=-15[/tex]

Evaluating a function means replacing the variable with the given value (3 for this case).

To evaluate the function, we need to remember that the absolute value guarantees a possitive value, for example:

[tex]|-3|=3\\|-4|=4[/tex]

So, we are given the function:

[tex]f(x)=|x|+(-2x^{2})[/tex]

Then, evaluating we have:

[tex]f(3)=|3|+(-2*(3)^{2})=3+(-2*9)=3-18=-15[/tex]

Hence, the answer is:

[tex]f(3)=|x|+(-2x^{2})=-15[/tex]

Answer:  [tex]x=8[/tex]

Step-by-step explanation:

Given the quadratic function  [tex]0=x^2-16+64[/tex], you need to follow these steps:

2. Now you need to factor the quadratic equation. Choose two numbers whose sum be -16 and whose product be 64.

These numbers are: -8 and -8.

Since the root appears twice, it is a "Double root". Then:

Answer:

Step-by-step explanation:

The measures of angle B and angle D of the given parallelogram will be 55°, i.e. option A.

Parallelogram is a 2D shape, having opposite sides parallel and equal. Also the opposite angles of parallelogram are congruent means equal.

We have,

A Parallelogram with,

Angle B = (2n + 15)° and,

Angle D = (3n - 5)°

So,

As mentioned above in the definition that the opposite angles of parallelogram are congruent means equal.

i.e.

Angle B = Angle D

i.e.

2n + 15 = 3n - 5

On solving we get,

20 = n

⇒ n = 20,

So,

Angle B = (2n + 15)° = (2 * 20 + 15)° = 55°

And,

Angle D = (3n - 5)° = (3 * 20 - 5)° = 55°

Hence, we can say that the measures of angle B and angle D of the given parallelogram will be 55°, i.e. option A.
