Answer 1

sub in 3.5 for x

f(3.5) = 280(3.5)
f(3.5) = 980

Answer 2

Answer: 980

Explanation:

Given : A machine produces 280 appliances per hour, the total number of appliances produced in x hours can be represented as a function:

`f(x)=280x`

The number of appliances can be produced in 3.5 hours is given by :-

`f(x)=280*3.5=980`

Therefore, the number of appliances can be produced in 3.5 hours is 980 .
