Answer:

Excluded values of the given function is -8.

Step-by-step explanation:

Given Function is $y=\frac{-2}{5x+40}$

We have to find Excluded values of the function.

We know that Values excluded from function are the values where functions cease to exist.

We are given a function with numerator and denominator.

So, When denominator becomes zero the function cease to exist.

⇒ Value of x when denominator become 0 are excluded from function.

Denominator from given function is 5x + 40

Put,

5x + 40 = 0

5x = 0 - 40

5x = -40

$x=\frac{-40}{5}$

x = -8

Therefore, Excluded values of the given function is -8.

In Terms of y:
y = -(2)/(5x) + 40
y = (-2) + (5x)40
y = 200x - 2/5x
In Terms of x:
y = -(2)/(5x) + 40
y = (-2) + (5x)40/5x
y = -2 + 5x • 40/5x
x = - 2/5y - 200

How to reduce into simpler terms.?

Sveta_85 [38]

Answer:

The simplest form of the fraction $\frac{45}{100}$ is $\frac{9}{20}$ .

i.e.

$\frac{45}{100}=\frac{9}{20}$

Step-by-step explanation:

Here are some simple observations regarding how to reduce a fraction into simpler terms:

A fraction is reduced to lowest or simplest terms by finding an equivalent fraction in which the numerator and denominator are as small as possible.

In order to reduce a fraction to lowest or simplest terms, divide the numerator and denominator by their (GCF). Note that (GCF) is also called Greatest Common Factor .

So, lets take a sample fraction and reduce into simpler terms.

Considering the fraction

$\frac{45}{100}$

$\mathrm{Find\:a\:common\:factor\:of\:}45\mathrm{\:and\:}100\mathrm{\:in\:order\:to\:cancel\:it\:out}$
