I need help please with linear function
1 answer:
I'm guessing you mean what a linear function is, answer provided below...
What is a linear function?:
linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable.
How to determine a linear function:
1. Identify the y-intercept from the graph.
2. Choose two points to determine the slope.
3. Substitute the y-intercept and slope into slope-intercept form of a line.
Here is a graph with a linear function:

Answer:
B. 12.5%
Step-by-step explanation:
Add all the hours together to get 20. We make the assumption that 20 is 100% since it is our output value. We next represent the value we seek with x. From step 1, it follows that 100%=20. In the same vein, x%=2.5.This gives us a pair of simple equations:
100%=20(1)
x%=2.5(2)
By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have
=
Taking the inverse (or reciprocal) of both sides gives us this:
>> x=12.5\%
Therefore, 2.5 is 12.5% of 20.
