For what values of the variables are the following expressions defined? 1. 5y+2 2. 18/y 3. 1/x+7 4. 2b/10−b Example: X>7

Serga [27]

Answer:

1. All real numbers

2. All real numbers except y = 0

3. All real numbers except x = -7

4. All real numbers except b = 10

Step-by-step explanation:

For any function to be defined at a particular value, it should not be approaching to a value $\infty$ or it should not give us the $\frac{0}{0}$ (zero by zero) form when the input is given to the function.

The value of function will depend on the denominator.

Now, let us consider the given functions one by one:

1. 5y+2

Here denominator is 1. So, it can not attain a value $\infty$ or $\frac{0}{0}$ (zero by zero) form

So, for all real numbers, the function is defined.

$2.\ \dfrac{18}{y}$

At y = 0, the value

$At\ y =0, \dfrac{18}{y} \rightarrow \infty$

So, the given function is defined for all real numbers except y = 0

$3.\ \dfrac{1}{x+7}$

Let us consider denominator:

x + 7 can be zero at a value x = -7

$At\ x =-7, \dfrac{1}{x+7} \rightarrow \infty$

So, the given function is defined for all real numbers except x = -7

$4.\ \dfrac{2b}{10-b}$

Let us consider denominator:

10-b can be zero at a value b = 10

$At\ b =10, \dfrac{2b}{10-b} \rightarrow \infty$

So, the given function is defined for all real numbers except b = 10

A translation moves point V(–2, 3) to V prime (negative 2, 7). Which are true statements about the translation?

vivado [14]

The true statements about the translation are:

The transformation rule is (x, y) right-arrow (x + 0, y + 4) ⇒ 2nd

The transformation is a vertical translation ⇒ 3rd

Step-by-step explanation:

Let us revise the translation of a point

If the point (x , y) translated horizontally to the right by h units then its image is (x + h , y)
If the point (x , y) translated horizontally to the left by h units then its image is (x - h , y)
If the point (x , y) translated vertically up by k units then its image is (x , y + k)
If the point (x , y) translated vertically down by k units then its image is (x , y - k)

∵ The coordinates of point V are (-2 , 3)

∵ The coordinates of point V' are (-2 , 7)

- The x-coordinate does not change but the y coordinate

changes, that means the translation is vertically only

∴ The translation is vertically

∵ The rule of the vertical transformation of point (x , y) is:

(x , y) → (x + 0 , y + k)

∵ The y-coordinate in V = 3

∵ The y-coordinate in V' = 7

∴ 3 + k = 7

- Subtract 3 from both sides

∴ k = 4

- That means point V is translated 4 units up

∴ The transformation rule is (x , y) → (x + 0 , y + 4)

The true statements about the translation are:

The transformation rule is (x, y) right-arrow (x + 0, y + 4)

The transformation is a vertical translation
