Answer:

(m º n)(x) = x -2

Step-by-step explanation:

Here, in the given expression:

m(x)= x+1 and n(x) = x - 3

To find : (m º n)(x)

Now, solving for (m º n)(x)

(m º n)(x) = m (n (x)) = m (x-3)

also, m (x-3) = (x -3) + 1 = x -2

So, (m º n)(x) = x -2

This year, a small business had a total revenue of $ 62 , 100. If this is 35 % more than their total revenue from the previous y

Olegator [25]

Answer:

$46000

Step-by-step explanation:

if x represents the previous years revenue, and they made 35% more than x, we need to find what 35% of x is and then add it to x to get the new total, so the equation becomes:

x + .35x = 62100

1.35x = 62100

x = 46000

Determine if the relation is a function and explain. a. {(-5,2), (-2,5), (0,7), (0,9)}

otez555 [7]

By definition we have to:
A mathematical function is a relationship that is established between two sets, through which each element of the first set is assigned a single element of the second set or none.
The initial set or starting set is also called the domain; the final set or set of arrival, meanwhile, can be called codomain.
We have the following information:
{(-5.2), (-2.5), (0.7), (0.9)}
The data does not represent a function because two different values of the range belong to an element of the domain:
(0.7)
(0.9)
Answer:
The relation is not a function.
