F(x) = 3x + 5/2
f(a+2) = 3(a+2) + 5/2 = 3a+6 + 5/2
= 3a + (12+5)/2 = 3a + 17/2

Answer:
a) 
b) 
Step-by-step explanation:
In both parts of the problem y varies directly as x. So, they have the following form:
Where k is the constant of proportionality.
Therefore, you must find k and then write the equations.
a) Solve for k:
Then, the equation is:
b) Solve for k:
Then, the equation is:
Answer:
(a) The probability is 0.64
(b) The probability is 0.59
Step-by-step explanation:
Say that an order requests at least one optional feature is equivalent to say that an order request one or more than one optional feature, So the probability can be calculated as the sum of this two proportions:
P = 0.23 + 0.41 = 0.64
Where 0.23 is the proportion or probability that an order request one optional feature and 0.64 is the probability that an order request more than one optional feature.
On the other hand, say that an order does not request more than one optional feature is equivalent to say that an order request zero or one optional feature, So the probability in this situation can be calculated as the sum of:
P = 0.36 + 0.23 = 0.59
Where 0.36 is the probability that an order doesn't request optional features and 0.23 is the probability that an order request one optional feature.
