1. A farmer finds there is a linear relationship between the number of beans stalks , n, she plants and the yield , y, each plants produces . When she plants 30 stalks , each plant yield 34oz of beans. When she plants 33 stalks, each plant produces 33oz of beans. find a linear relationship in the form y =mn+b that gives the yield when n stalk are planted. y=

2. Determine if the point are solution point to are solution points to the inequalities below if the point is a solution enter yes.

a. Is (13, 15) a solution to y < 18-x ?

b. Is ( 4,10) a solution to y 13-x?

c Is (5,12) a solution y > 14-x ?

d Is (6,6) y 13-x?

6. A poll results of 72% with a margin of error of 4% indicates that p is most likely to be 68% and 76%(72% minus 4% to 72% plus 4%).

In a (made up) poll, the proportion of people who like dark chocolate more than milk chocolate was 32% with a margin of error 1.6%. describe the conclusion about p using an absolute value inequality.

use decimal in the answer.

7. Solve the system of equations.

-2x+5y=-35

7x+2y=25

Enter the answer as pair (x, y)

8. solve the system of equation by any method.

6x+11y=17

x+2y=4

enter the answer aas pair (x,y)

9. Use a system of linear equations with two variables and two equation to solve.
