What is the value of 6 x 3/8?

In the given Isosceles trapezoid, the value of x and y is 12 and 5 respectively.

An isosceles trapezoid, or isosceles trapezium in British English, is a convex quadrilateral in Euclidean geometry that has a line of symmetry cutting through one pair of opposite sides.

It is an uncommon instance of a trapezoid.

Alternately, it can be described as a trapezoid with equal amounts of both the base angles and the legs.

Note that the second requirement, or the fact that it lacks a line of symmetry, prevents a non-rectangular parallelogram from being an isosceles trapezoid.

Two opposite sides (the bases) of each isosceles trapezoid are parallel, while the remaining two sides (the legs) are each the same length (properties shared with the parallelogram).

So, solve for x and y:

For x:

4x - 27 = x + 9

3x = 36

x = 36/3

x = 12

For y:

3y + 19 = 11y - 21

8y = 19 + 21

8y = 40

y = 40/8

y = 5

Therefore, in the given Isosceles trapezoid, the value of x and y is 12 and 5 respectively.

The value of the matrix multiplication A x B is matrix C

The value of B is   [tex]B = \begin{pmatrix}x\\ y\end{pmatrix} = \begin{pmatrix}8\\ 8\end{pmatrix}[/tex]

What is multiplication of matrices?

The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. The first matrix must have the same number of columns as the second matrix has rows. The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix

Given data ,

The number of shirts sold by club A = 2

The number of notebooks sold by club A = 3

The number of shirts sold by club B = 1

The number of notebooks sold by club B = 1

Now , the value of matrix A is

[tex]A = \begin{pmatrix}2&3\\ 1&1\end{pmatrix}[/tex]

The value of matrix B is

[tex]B = \begin{pmatrix}x\\ y\end{pmatrix}[/tex]

The product of matrix A and B will be C , and the value of matrix C is

[tex]C = \begin{pmatrix}40\\ 16\end{pmatrix}[/tex]

So , the equation is

A x B = C

Substituting the values in the equation , we get

[tex]\begin{pmatrix}2&3\\ 1&1\end{pmatrix}\begin{pmatrix}x\\ y\end{pmatrix}=\begin{pmatrix}40\\ 16\end{pmatrix}[/tex]

On simplifying the equation , we get

[tex]\begin{pmatrix}2x+3y\\ x+y\end{pmatrix}=\begin{pmatrix}40\\ 16\end{pmatrix}[/tex]

So , the equations are

2x + 3y = 40   be equation (1)

x + y = 16   be equation (2)

Multiply equation (2) with 2 , we get

2x + 2y = 32   be equation (3)

Now , subtracting equation (3) from equation (1) , we get

y = 8

Substituting the value for y in equation (2) , we get

x + 8 = 16

Subtracting 8 on both sides of the equation , we get

x = 8

Therefore , the value of x is 8 and y is 8

Hence , the value of matrix B is   [tex]B = \begin{pmatrix}x\\ y\end{pmatrix} = \begin{pmatrix}8\\ 8\end{pmatrix}[/tex]

What is a linear equation?

The graphs of all first-degree equations in two variables will be straight lines. This fact will be used here even though it will be much later in mathematics before you can prove this statement. Such first-degree equations are called linear equations.

Here, we have

Given inequalities

x - y < 5

y ≥ 2x - 4

We have to describe the graph of the system of inequalities.

For, x < 5+y

x = 5-y

We put y = 0, we get

x = 5

We put x =0, and we get

y = 5

Hence, the x = 5-y line passes through (0,5) and (5,0).

For, y ≥ 2x - 4

y = 2x -4

We put x = 0, and we get

y = 4

We put y = 0, we get

x = 2

Hence, the y = 2x -4 line passes through (0,4) and (2,0).

Answer:

B. 50

Step-by-step explanation:

Let x be the number of coupons sent to existing members.

The number of coupons sent to potential members is 4 times the number of coupons sent to existing members, or 4x.

The total number of coupons sent is the sum of the number of coupons sent to existing members and the number of coupons sent to potential members, or x + 4x = 5x.

The club sent out 250 coupons, so 5x = 250.

Dividing both sides of the equation by 5, you get x = 250 / 5 = 50.

Therefore, the club sent 50 coupons to existing members.

Answer:

it is 180

Step-by-step explanation:

The first step to start the is dividing both sides by 3, so the correct option is the second one.

The linear equation in slope-intercept form is:

y = (1/2)*x + 1

To do that, we need o isolate the variable y in one of the sides of the linear equation:

3*(x + 2) = 6y

We can divide both sides by 3 to get:

x + 2 = (6/3)*y

x + 2 = 2y

Now, we can divide both sides by 2, so we will get:

(x + 2)/2 = y

y = (x + 2)/2

y = (1/2)*x + 1

The equation in the slope-intercept form is:

y = (1/2)*x + 1

A function is a relation where each conceivable input value results in exactly one potential output value. The phrase "the output is a function of the input" frequently used.

An expression, rule, or law in mathematics that specifies the relationship between an independent variable and a dependent variable (the dependent variable). In mathematics and the sciences, functions are fundamental for constructing physical relationships.

An example of a rule is a function, which produces one output for a single input. Alex Federspiel is the picture's author. Y=X2 is an illustration of this. You only get one output for y if you enter anything for x. The fact that x is the input value leads us to say that y is a function of x.
