Suppose that a bike rents for 50php plus 8php per hour. Write an equation in slope-intercept form that models this situation.

Answers

Answer: C(x) = (8 php)*x + 50 php.

Step-by-step explanation:

In a linear equation:

y = a*x + b

a is the slope.

x is the variable

b is the y-intercept.

In this case, we have

The rent is 50 php fixed, plus 8 php per hour.

Then we will pay the 50php only one time, and it does not depend on the number of hours that we rent, then this is the y-intercept.

then if we rent the bike for x hours, we will pay a plus of x*8 php.

Then the total cost for x hours, C(x), will be

C(x) = (8 php)*x + 50 php.

Then the slope is 8 php, and the y-intercept is 50 php.

The sum of 3 consecutive odd natural nos. can be represented by n + ( n+2 ) + (n + 4 ).

What are consecutive nos. ?

Consecutive nos. are every no. after each other.

According to the given question we have to represent the sum of 3 consecutive odd natural nos.

We know that consecutive odd natural nos. come after every two digits.

∴ Assuming the first odd natural no. to be n.

So, Next odd natural no. will be (n + 2) and the third consecutive odd natural no. will be (n + 2) + 2 which is = (n + 4).

∴ The sum of 3 consecutive natural numbers can be represented by

n + (n + 2) + (n+4).
