Solve the equation<br> 2x-3=15<br> A)x=6<br> B)x=9<br> C)x=24<br> D)x=36
DaniilM [7]
To solve the equation, it is necessary to isolate the unknown variable "x" first. This is done as shown below:

2x - 3 = 15

Adding 3 to both sides of the equation:

2x - 3 + 3 = 15 + 3
2x = 18

Dividing 2 from both sides:

2x/2 = 18/2
x = 9

Among the choices, the correct answer is B.

Help neeed help please

reflection and translation.

Given:

The different transformation in the options.

To find:

The transformation that would result in the perimeter of a triangle being different from the perimeter of its image.

Solution:

In option 1,

(x,y)\to (y,x)

It represents reflection across the line y=x.

In option 2,

(x,y)\to (x,-y)

It represents reflection across the x-axis.

In option 3,

(x,y)\to (4x,4y)

It represents dilation by scale factor 4 and the center of dilation is at origin.

In option 4,

(x,y)\to (x+2,y-5)

It represents translation 2 units right and 5 units down.

We know that the reflection and translation are rigid transformations, It means the size and shape of the figure remains the same after transformation.

So, the perimeter of the figure and its image are same in the case of reflection and translation.

But dilation is not a rigid transformation. In dilation, the figure is similar to its image. So, the perimeter of the figure and its image are different in the case of dilation.

Therefore, the correct option is 3.

A number to the 10 power divided by the same number to the 7th power equals 125 what is the number?
Tanzania [10]
The number is 5. All you have to do is make an equation based on the information you have, x will represent the missing number so, x to the power of 10 divided by x to the power of 7 is equal to 125, then solve.

State whether the equation represents exponential growth, exponential decay, or neither.
Mila [183]

Answer:

Neither

Step-by-step explanation:

This questions only states

y = 11.1.07\%

This is not a fucntion because there is no variable.

This is not a valid statement, because 11.1.07% is non-sensical.
