<h2>5</h2>
Step-by-step explanation:
Given the expression f(z) = 9-z
To get the value of the resulting value of the function when z = 4, all we need to do is substitute the value of z given into the function to have;
f(4) = 9-4
f(4) = 5
The right answer is 5
Answer:
1) 25+7(n-1)
When the above 'n'(hours) is substituted on the equation, it equals up to the right cost.
2) Given that n represents the no.of bikes, you just plug it in to the equation below.
250+39(n-1)
= 250+39(20-1)
= 250+39*19
= 250+741
= 991
