1. suppose you are saving money for a new cell phone. at week 0 you have $20 and at week 10 you have $100. if y represents the amount of money you have saved and x represents the number of weeks, find and interpret the slope of the linear equation.
1. 1/8; $8 is put away each
week.
2. 10; $10 is put away each week.
3. 8; $8 is put away each week.
4. 1/10; $10 is put away each week.

2. if a function f (x) is shifted to the left one unit, what function represent the transformation?
1.f (x+1)
2. f (x- 1)
3. f (x)+1
4. f (x)- 1

3. let g (x) be the reflection of f (x)=x^2+5 in the x- axis. what is the function rule for g(x)?
1. g (x)=- x^2- 5
2. g (x)=x^2+5
3. g (x)=x^2- 5
4. g (x)=- x^2+5

4. what transformations change the graph f (x) to the graph g (x)? f (x)=- 7x^2 g (x)=-35x^2+5
1. the graph stretched vertically by a factor of 1/5 and slanted down 5 units
2. the graph stretched vertically by a factor of 5 and translated down 5 units.
3. the graph stretched vertically by a factor of 1/5 and translanted up 5 units.
4. the graph stretched vertically by a factor of 5 and translated up 5 units.

8. write an equation for the following transformation of y=x a vertical stretch by a factor of 6.
1.y=6x
2. y=x/6
3. y=x+6
4. y=x-6

9. what transformations change the graph of f (x) to the graph of g (x).
1. the graph of g is the graph of f translated to the right 3 units and up 7 units.
2. the graph of g is the graph of f translated to the left 3 units and down 7 units.
3. the graph of g is the graph of f translated up 3 units and to the left 7 units.
4. the graph of g is the graph of f translated down three units and the right 7 units.

10. a cannery processed 1445 pounds of strawberries in 4.5 hours the cannery processed 2320 pounds in 7 hours. write a linear equation to model the relationship between the weight of strawberries and the time too. how many pounds of strawberries can be processed in 11 hours.

11. a doctors office schedules 15 minute appointments and half hour appointments for weekdays. the doctor limits these appointments to at most 30 hours per week write an inequality to represent the number of 15 minute appointments x and the number of half hour appointments why the doctor may have in a week.
