Multiply the input by 3/4 ,then add 2

Step-by-step explanation:

Let

x-------> the input (independent variable)

y------> the output (dependent variable)

we know that

This is a linear equation-------> equation of a line

To graph the line

Find the intercepts

The y-intercept is the point ---> value of y when the value of x is equal to zero

The x-intercept is the point ---> value of x when the value of y is equal to zero

Plot the points

The graph in the attached figure

2.512

Step-by-step explanation:

the equation for circumference of a circle is

2(pi)r

plug in the 4

2(pi)4

combine like terms

8(pi)

you can leave the answer as is or you can multiply

8(3.14)= 2.512

the answer would be 2.512

***pi is equal to 3.14, if you are not allowed to keep your answer in terms of pi there is a pi button on the calculator you can use, or simply plug in 3.14
