F(x) = x + 5 If you know that the range is {0, 10}, then... The domain must be ??

Vaselesa [24]

Answer:

domain {- 5, 5 }

Step-by-step explanation:

given values in the range, that is values of y then to find the domain equate f(x) to the given values in the range, that is

x + 5 = 0 ⇒ x = - 5

x + 5 = 10 ⇒ x = 10 - 5 = 5

domain is x ∈ { - 5, 5 }

Given:

A car traveled 150 km in 3 hour.

To find:

The unit rate.

Solution:

We have,

Distance = 150 km

Time = 3 hours.

In this case speed is the unit rate.

$Speed=\dfrac{Distance}{Time}$

Substituting the given values, we get

$Speed=\dfrac{150\text{ km}}{3\text{ hr}}$

$Speed=50\text{ km/h}$

Therefore, the unit rate is 50 km/h.
