which expressions are equivalent to 5x + 6y - 3x

Answer: C

Step-by-step explanation:

Subtract 12 from both sides

y + 12 - 12 = 16 - 12

y = 4

By subtracting 12 from both sides, we isolate y and get the final answer

Answer:

33/4

Step-by-step explanation:

x^-2 = 1/x^2

x^2 = ( 2/3 )^2

      = 2^2 / 3^2

x^2 = 4/9

x^-2 = 9/4

27^x

27 = 3 x 3 x 3 = 3^3

27^x = 3^3x

        = 3^( 3* 2/3 )

        = 3*2

27^x = 6

x^-2 + 27^x

= 9/4 + 6

= 9/4 + 24/4

= ( 9 + 24 )/4

= 33/4

Answer:

x=3

Step-by-step explanation:

Hey there!

In order to solve this equation, we must first distribute the 3

3x + 9 = -4x + 30

Now we combine like terms

7x = 21

Then we divide both sides by 7 to get x by itself

x = 21/7

x = 3

Answer: x=3

Step-by-step explanation:

To solve the given equation, it means to find the value of x. We want to use inverse properties to isolate x. The inverse properties are add/subtract and multiply/divide. Be sure to use the corresponding inverse operation.

3(x+3)=-4x+30                 [distribute]

3x+9=-4x+30                    [add both sides by 4x]

7x+9=30                            [subtract both sides by 9]

7x=21                                 [divide both sides by 7]

x=3

Therefore, we get x=3.

The loss on selling 50 shares of stock would be 87.50.

To calculate the loss on selling 50 shares of stock originally bought at

\(13\frac{3}{4}\) and sold at 12, we need to determine the difference between the purchase price and the selling price, and then multiply it by the number of shares sold.

First, let's convert the purchase price from a mixed fraction to a decimal. \(13\frac{3}{4}\) can be expressed as 13.75.

Next, we calculate the difference between the purchase price and the selling price:

\(13.75 - 12 = 1.75.\)

Finally, we multiply the difference by the number of shares sold:

\(1.75 \times50 = 87.50.\)

Therefore, the loss on selling 50 shares of stock would be 87.50.

Answer:

j ≥ -44

Step-by-step explanation:

-2/11 j ≤ 8

Multiply each side by -11/2 to isolate j.  Flip the inequality since we are multiplying by a negative

-11/2 * -11/2 j ≥ 8 * -11/2

j ≥ -44

Answer:

\(j\geq -44\)

Step-by-step explanation:

The inequality given is:

\(\frac{-2}{11}j\leq 8\)

To solve the inequality, we must get the variable j by itself.

j is being multiplied by -2/11. To reverse this, we must multiply by the reciprocal of the fraction.

Flip the numerator (top number) and denominator (bottom number) to find the reciprocal.

\(\frac{-2}{11} --> \frac{-11}{2}\)

Multiply both sides of the equation by -11/2.

\(\frac{-11}{2} *\frac{-2}{11} j \leq 8*\frac{-11}{2}\)

\(j\leq 8*\frac{-11}{2}\)

Since we multiplied by a negative number, we must flip the inequality sign.

\(j\geq 8*\frac{-11}{2}\)

Multiply 8 and -11/2

\(j\geq 8*-5.5\)

\(j\geq -44\)

The solution to the inequality is: \(j\geq -44\)

Answer:

8

Step-by-step explanation:

Substitute the values in the expression, we have:

\(\displaystyle{|-1-3|+4}\)

Evaluate:

\(\displaystyle{|-4|+4}\)

Any real numbers in the absolute sign will always be evaluated as positive values. Thus:

\(\displaystyle{|-4|+4 = 4+4}\\\\\displaystyle{=8}\)

Hence, the answer is 8. A quick note that z-value is not used due to lack of z-term in the expression.

Answer:

n = 26/45

Step-by-step explanation:

If the 9⅓ and 27⅘ are supposed to be \(9^{1/3}\)  and \(27^{4/5}\), then

\(9^{1/3}\) × \(27^{n}\) = \(27^{4/5}\)

=> \((3^{2})^{1/3}\) × \((3^3)^{n}\) = \((3^3)^{4/5}\)

=> \(3^{2/3}\) × \(3^{3n}\) = \(3^{12/5}\)

=> \(3^{3n+\frac{2}{3}}\) = \(3^{12/5}\)

=> 3n+2/3 = 12/5

=> 45n + 10 = 36

=> 45n = 26

=> n = 26/45

The lines are parallel because they have the same slope in the equation of lines

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first equation be 9y - 6x = -18   be equation (1)

Let the second equation be 3y - 2x = 24   be equation (2)

On simplifying the equation , we get

Adding 6x on both sides of the equation , we get

9y = 6x - 18

Divide by 9 on both sides of the equation , we get

y = ( 2/3 )x - 2

So , the slope of line 1 is m = 2/3

And , for the second equation ,

Adding 6x on both sides of the equation , we get

3y = 2x + 24

Divide by 3 on both sides of the equation , we get

y = ( 2/3 )x + 8

So , the slope of line 2 is m = 2/3

Since the slopes of the lines are same , they are parallel lines

Hence , the equation of lines are solved

By using the concept of internal angles of a triangle, the solution of the system of linear equations related to the geometrical system is (x, y) = (40, 40).

In this system we have a geometrical system formed by two right triangles with a common hypotenuse. Right triangles are triangles where one of its internal angles are right angles and the sum of the measures of the internal angles within a triangle equals 180°. Then, this geometrical system can be modelled by using the following linear equations:

(x + 20) + 90 + 30 = 180         (1)

20 + 90 + (y + 30) = 180         (2)

By using the concept of internal angles of a triangle, the solution of the system of linear equations related to the geometrical system is (x, y) = (40, 40).

Jessica needs 7 book shelves for 137 books in given word problem.

What is word problem?

Mathematical questions that are written as one or more sentences and ask students to use their mathematical understanding to solve problems from "real-life" situations are known as word problems. As a result, for kids to understand the word problem, they need to be familiar with the vocabulary that goes along with the mathematical symbols that they are already used to. In addition to being in the Common Core State Standards for every school level, K–12, word problems and story issues also occur in daily life. The three primary sorts of word problems—part-part whole, separate and join, and multiply and divide—can be used for anything from tip calculation to penny counting.

Here the total number of books = 137.

We can arrange 20 books in each shelves. Then ,

=> 20+20+20+20+20+20 = 120

So we can arrange 120 books in 6 shelves in each shelves in 20 books.

The remaining books= 137-120=17

In 7th shelves we can arrange `17 books.

Therefore we need 7 shelves for 137 books.

\(\displaystyle{f(x)=3^x-5}\)

Step-by-step explanation:

Being translated up-down means that the value exists outside of x. Therefore, we can cancel B and C choice since those are horizontal (left-right) translation.

Our only choice is A and D. However, D is being translated up since it's +5. Thus, the only correct answer that a function is being translated down is:

\(\displaystyle{f(x)=3^x-5}\)

or A choice.

The accurate statement about the graph is: Point D is a y-intercept of the graph.

Based on the given graph of y = -x + 1, the following statements about the graph are accurate:

Point A is a relative minimum of the graph:

False.

Point A is located at (-2, 3), and it is not the lowest point on the graph. Moving to the left or right of point A, the graph continues to decrease.

Point B is a turning point of the graph:

False.

Point B is not a turning point.

It is located at (-1, 2), and the graph does not change its direction or slope at this point.

Point C is a maximum of the graph:

False.

Point C is located at (2, -2), and it is not the highest point on the graph. Moving to the left or right of point C, the graph continues to increase.

Point D is a y-intercept of the graph:

True.

Point D is located at (0, 1), and it lies on the y-axis.
