Movies-At-Home will give her the DVD for 5 days at $5.00 and charges $1.75 per day for a late return. For how many days can she keep the movie if the total cost to her is the same at both stores? This is the break even day.
|
Let D = the number of days the two move prices break even.
- The expression for Happy Viewing is: _________________
- The expression for Movies_At_Home is : ________________
- Set these 2 expressions equal to each other and solve for D:
D = _____

4) Lisa is designing her own house. She draws a
side view sketch of the stairs she wants to use to
connect the downstairs with the upstairs. She
notices there's a line that connects all the edges of
the steps as shown in the diagram. If the coordinates
giving the edge of the second step are ( 2ft, 3/2ft),
what are the coordinates of the edge of the top step?
|
You must find the equation for a line given the coordinates of the second step and the fact that the line passes through the origin.
- The equation is of the form y = mx + b where:
m is the slope and b is the y-intercept
- The y-intercept (b) is _____
- The slope (m) = ___________
The equation is y = __________________
- The top step is at x = ____, so
    y = ________________________
- So the coordinates of the top step are (___,___)
