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.

What is mathematical function?

A function in mathematics from such a set X to either a set Y allocates exactly 1 element of Y to every element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

A planet's position, for instance, depends on time. In the past, the idea was developed with both the infinitesimal calculus toward the conclusion of the seventeenth century, and the functions that were taken into consideration were differentiable until the 19th century. Graphs E, B, as well as D all represent functions and relations, respectively.

Therefore, graphs E, B, as well as D all represent functions and relations, respectively.

For this you would set up a ratio

8minutes/64 gallons

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).
