Answer:
It will take them 3.43 hours.
Step-by-step explanation:
Let T denote the total cookies that need to be cocked. Observe that:
- If Rosanne finishes the cookies in 6 hours, that means that she can make
cookies per hour.
- If Dorothy finishes the cookies in 8 hours, that means that she can make
cookies per hour.
Then, by 1) and 2), if they work together would we able to make
cookies per hour.
Therefore, in order to finish the T cookies they will need
Answer:
Pat a) The graph in the attached figure
Part b)
The slope is
The y-coordinate of the y-intercept is
Step-by-step explanation:
Part a) Which line represents the linear equation ?
To graph the linear equation find the intercepts
we know that
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0
The y-intercept is the point
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0
The x-intercept is the point
Plot the intercepts to graph the linear equation
see the attached figure
Part b) Rewritten in slope-intercept form
we know that
The equation of the line into slope intercept form is equal to
where
m is the slope
b is the y-coordinate of the y-intercept
we have
convert to slope intercept form
isolate the variable y
The slope is
The y-coordinate of the y-intercept is
