Suppose that f and g are two functions with the same domain. If f(x)equalsg(x) for every x in the domain, the equation is cal

stealth61 [152]

Answer:

Identity; conditional

Explanation:

Identity functions are functions that returns the SAME value which was used in its argument. In this case, f(x) = g(x). Therefore f(x) = g(x) = x.

Conditional functions are conditions that evaluates the condition and returns DIFFERENT values all depending on the condition value. That is, in this case, f(x) is not equal to g(x) for every x domain.

So, while identity functions returns the same value, conditional functions returns different functions.

Simplify urgent pls

Sonbull [250]

Answer: VI)

$\frac{x - 1}{3(x+ 1)}$

VII)

$\frac{2(m - 7) \times (m + 7)}{n(n - 7)}$

Step-by-step explanation:

VI)

$\frac{{(x + 1)}^{2}}{6} \times \frac{2}{{x}^{2} - 1}$

$= \frac{2{(x - 1)}^{2} }{6(x - 1) \times (x + 1)}$

$= \frac{x - 1}{3(x+ 1)}$

VII)

$\frac{{m}^{2} - 49}{3n} \div \frac{2n - 14}{6}$

$= \frac{(m - 7) \times (m + 7)}{3n} \times \frac{6}{2(n - 7)}$

$= \frac{2(m - 7) \times (m + 7)}{n(n - 7)}$

Can't type fast enough, LaTex is hard :(

The Tama, Japan, monorail carries 92,700 riders

Damm [24]

Answer:

The monorail runs 18 hours runs every day.

Step-by-step explanation:

You know that the total number of riders the monorail carry each day is 92700 and the number of riders the monorail carry per hour is 5150.

The rule of three or is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.

A direct proportionality relationship is established between two quantities if:

The greater the quantity in one quantity, the greater the quantity in the other quantity, in the same proportion.
The less quantity in the magnitude corresponds to the less quantity in the other magnitude, in the same proportion.

If the relationship between the magnitudes is direct the direct rule of three must be applied and to solve a direct rule of three, the following formula must be followed:

a ⇒ b

c ⇒ x

Being

$x=\frac{c*b}{a}$

In this case the rule of three can be applied in the following way: if the monorail carries 5,150 passengers in 1 hour, the monorail will transport 92,700 passengers in how many hours?

$amount of hours=\frac{92,700 passengers*1hour}{5,150 passengers}$

amount of hours= 18 hours

So the monorail runs 18 hours runs every day.
