If a(x) = 3x + 1 and (x)= x-4, what is the domain of (boa)(x)?
Ipatiy [6.2K]

I am assuming you meant to write b(x) = x-4.

(b \circ a)(x)=b(a(x))=b(3x+1)=(3x+1)-4=\boxed{3x-3}

Since this is a linear function, the domain is all real numbers.

Which is a step in the process of calculating successive discounts of 8% and 10% on a $50 item
Paraphin [41]

Answer:

The  process of calculating successive discounts of 8% and 10% on a $50 item is take 10% of $46.

Step-by-step explanation:

As given

successive discounts of 8% and 10% on a $50 item .

First find out for 8 % discount

8% is written in the decimal form

= 0.08

8 % of $50 item = 0.08 × 50

                          = $ 4

Price of item after 8% discount = 50 - 4

                                                    = $46  

First find out for 10 % discount

10% is written in the decimal form

= 0.1

8 % of $48 item = 0.1× 46

                          = $4.6

Price of item after 8% discount = 46 - 4.6

                                                    = $41.4

Therefore in the successive discounts of 8% and 10% on a $50 item is $41.4 .
