<span>(f+g)(x) if f(x)=2/x+1 and g(x)=x-2

Add f and g together: (f+g)(x) = (2/x) + 1 + x - 2 = (2/x) + x - 1</span>

Answer:

The number of birds are 6 and number of cats are 21 at the shelter on Thursday .

Step-by-step explanation:

Let us assume that the number of bird be x .

Let us assume that the num ber of cat be y .

As given

An animal shelter spends $4.50 per day to care for each bird and $5.50 per day to care for each cat. Nathaniel noticed that the shelter spent $142.50 caring for birds and cats on Thursday.

4.50x + 5.50y = 142.50

Simplify the above

$\frac{450x}{100} + \frac{550y}{100} = \frac{14250}{100}$

450x + 550y = 14250

As given

Nathaniel found a record showing that there were a total of 27 birds and cats on Thursday.

x + y = 27

Two equations are

450x + 550y = 14250

x + y = 27

Multiply x + y = 27 by 450 and subtracted from 450x + 550y = 14250 .

450x - 450x + 550y - 450y = 14250 - 12150

100y = 2100

$y = \frac{2100}{100}$

y = 21

Putting the value of y in the equation x + y = 27 .

x + 21 = 27

x = 27 - 21

x = 6

Therefore the number of birds are 6 and number of cats are 21 at the shelter on Thursday .
