[tex]9x-5=3x+7[/tex]

Subtract 3x from both sides:

[tex]9x-5-3x=3x+7-3x[/tex]

[tex]6x-5=7[/tex]

Add 5 to both sides:

[tex]6x-5+5=7+5[/tex]

[tex]6x=12[/tex]

Divide both sides by 6:

[tex]\dfrac{6x}{6} =\dfrac{12}{6}[/tex]

[tex]\fbox{x = 2}[/tex]

Answer:

[tex] \sf \: x = 2[/tex]

Step-by-step explanation:

Now we have to,

→ find the required value of x.

The equation is,

[tex] \sf \rightarrow \: 9x - 5 = 3x + 7[/tex]

Then the value of x will be,

[tex] \sf \rightarrow \: 9x - 5 = 3x + 7[/tex]

[tex] \sf \rightarrow \: 9x - 3x = 7 + 5[/tex]

[tex] \sf \rightarrow \: 6x = 12[/tex]

[tex] \sf \rightarrow \: x = \frac{12}{6} [/tex]

[tex] \sf \rightarrow \: x = 2[/tex]

Hence, the value of x is 2.

As a result of the inverse relationship between z and w, their product is constant.

There is an inverse relationship between two parameters when they are connected, where the value of one parameter tends to decrease as the value of the other parameter increases. It's often described as a "bad friendship" in conversation.

z * W is equal to 1.

The statement indicates that the constant's value is 2/3, so:

z * w = 2/3

The result of solving for any of the variables is:

either w = (2/3) / z or z = (2/3) / w

The following values fit that relation:

z w = (2/3) / z

-8/9 (2/3) / (-8/9)

= - (2/3) * (9/8) = -3/4

- 4/9 (2/3) / (-4/9)

= - (2/3) * (9/4) = - 3/2

- 2/9 (2/3) / (-2/9)

= - (2/3) * (9/2) = - 3

2/9 (2/3) / ( 2/9)

= (2/3) * (9/2) = 3

4/9 (2/3) / (4/9)

= (2/3) * (9/4) = 3/2

The measures of missing angles in trapezoids are listed below:

Case 5: m ∠ J = 75°, Case 7: m ∠ T = 118°

In this question we must determine the measures of missing angles in trapezoids. There are two hints to determine the values of the missing angles:

Now we proceed to determine the missing angles in every trapezoid:

Case 5

m ∠ K + m ∠ J = 180°

21 · x + 15 · x = 180°

36 · x = 180°

x = 5

m ∠ J = 15 · x

m ∠ J = 15 · 5

m ∠ J = 75°

Case 7

m ∠ U = m ∠ T

m ∠ T = m ∠ U

m ∠ T = 118°

Answer: 0.155

Step-by-step explanation:

To find the probability of a certain event occurring in a Poisson distribution, we can use the formula:

P(k) = (μ^k * e^(-μ)) / k!

Where:

Plugging in the given values, we get:

P(5) = (9^5 * e^(-9)) / 5! = 126,441 * 0.000123 = 0.1550

So the probability of the event occurring 5 times is approximately 15.5%.

The answer is the 3rd graph!

The requried graph of equation x - y = 6 is shown in graph C.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

Here,

The given condition is x - y = 6, which is a linear equation with a slope of 1 and a y-intercept of -6. We can also rewrite this equation in slope-intercept form as y = x - 6.

To graph this equation, we can plot the y-intercept at (0, -6), and then use the slope of 1 to find other points on the line. For example, if we move one unit to the right from the y-intercept, we will also move one unit up to get to the point (1, -5).

Therefore, the correct graph is C.

Analysing the given figures of the triangles ABC and A'B'C' , the required transformation for changing the traingle ABC to A'B'C' is the translation.

In a two-dimensional space, a translation transformation can be represented by a matrix of the form [1 0 Tx], [0 1 Ty], where Tx and Ty are the horizontal and vertical translation values, respectively. The matrix shows the movement of an object in the x and y directions, with Tx representing the horizontal shift and Ty representing the vertical shift.

A translation transformation moves an object from one position to another without changing its size or orientation. The shape and size of the object remain the same, but its position changes. The object is moved along a specific direction by a certain distance, and the position of the object within a coordinate system is changed. The effect of a translation can be visualized as sliding an object along a surface, while keeping its orientation and size unchanged.

As we can see from the given graph that the traingle ABC has moved straight downward without any changes in the orientation and the size of the traingle while being transformed to traingle A'B'C', Hence the transformation is translation transformation.

[tex]\large{\colorbox{black}{\color{pink}{EXPLANATION:}}}[/tex]

Answer:

226 cm^2

Step-by-step explanation:

It’s literally a rectangular prism If you put it together. The side with 2 cm and 11 cm , the surface area is 22 and since this is a rectangular prism, that means there is a second of the same kind. Then you get the larges box, since you know that the top side is 11 and the left side is 7, you multiply that * 2 which you then get 154. You add that up with the side that you solved before so 154 + 44 = 198. You then figure out the left side 7 * 2 * 2 (because there are two of them). 28 + 198 = 226 cm^2.  

Answer:

226 cm^2

Step-by-step explanation:

11*2 + 7*2 + 7*2 + 11*7 + 11*2 + 7*11

= 22+ 14 +14+ 77+ + 22 + 77

= 226

Answer: It is not possible for me to draw a slope triangle or dilate it along the graph without more information about Sara's monthly savings.

To determine whether the amount Sara saves each month is constant, you can choose any two points on the graph and use them to calculate the slope of the line connecting them. If the slope is constant for all pairs of points, then the amount Sara saves each month is constant. If the slope is not constant, then the amount Sara saves each month is not constant.

To calculate the slope of the line connecting two points, you can use the following formula:

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

where (x1, y1) and (x2, y2) are the coordinates of the two points.

You can then use the slope triangle to visualize the slope of the line connecting the two points. If you dilate the slope triangle along the graph and the slope remains constant, then the amount Sara saves each month is also constant.

Complete the puzzles with values -4, 0, -3 and 2

Since each row, column, and diagonal adds up to the same total.

For the 1st row, the total is:

3 + (-2) + (-1) = 0

That means each row, column, and diagonal will always adds up to 0.

3 + w + 1 = 0

w = -3-1

w = -4

w + y + 4 = 0

-4 + y + 4 = 0

y = 0

-1 + 4 + t = 0

3 + t = 0

t = -3

1 + h + t = 0
