The function y=1.5+0.35x represents the price y for a taxi ride of x miles. What numbers are not reasonable domain values

Answers

Answer 1
Answer:

The set of all negative real numbers is unreasonable domain values

What are functions?

Function, in mathematics, is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given here, the function  y=1.5+0.35x. Now since the distance is the magnitude and hence a scalar quantity thus the domain cannot be negative numbers thus the valid domain for this function is [0,∞)

Hence, the domain (-∞,0) is the domain of unreasonable values.

Answer 2
Answer: If you ride x miles, the price y will be:

y=1.5+0.35x

You can ride any number of miles you want. But what you can't ride negative miles.

So negative numbers are not reasonable domain values.

framing in equation form we get;

Also Given:

The Smith's spent $ 26 on movie tickets for 2 adults and 2 children

Number of adult tickets = 2

Number of children ticket = 2

Total money spent = $26

So we can say that;

Total money spent is equal to sum Number of adult tickets multiplied by cost of each Adult ticket and sum Number of children tickets multiplied by cost of each child ticket.

framing in equation form we get;

Now Subtracting equation 2 from equation 1 we get;

Now substituting the value of y in equation 1 we get;

Hence Cost of adult ticket is $8 and Cost of children ticket is $5.

Answer:

adult ticket- $8

child ticket-$5
