6:00-30 minutes is 5:30
5:30-15 minutes is 5:15
5:15-45 minutes is 4:30
She started on 4:30 pm
Answer: It's a function.


Step-by-step explanation:

The domain is all of the x values; remember each parenthesis is (x,y)

The range is all of the y values.


1) As we can see this is a Linear Equation written in the Slope-intercept form:

Note that "m" stands for the slope of the line, i.e. the measure of how steep a line is.
In the given equation, we can state that the slope is always accompanying the "x" therefore, the slope is m= 7
2) In addition to this, the y-intercept also called the Linear Coefficient is given by the letter"b" and represents the y-coordinate that the graph intercepts. Thus the y-intercept is -6
So we can state the following as the answers:

And that is the answer
Answer:
0=w^2-5.2w-51
Step-by-step explanation:
51=width x length
length=width-5.2
substitute for length
51=width x (width-5.2)
51=w^2-5.2w
0=w^2-5.2w-51
