How do you do question 9? if you answer explain.

bottom left is -2x and bottom right is -3

Step-by-step explanation:

if you were to use a timeline you subtract 5 from 3 and that leaves you -2 and add the x from before and for the bottom right 2 - 5 is negative three if you need help its easy to make a timeline

Step-by-step explanation:

Let x represent the number of pounds of fruit that you can buy.

Let y represent the number of pounds of fruit that you can buy.

You need to buy at least 20 of them. This means that

x + y ≥ 20 - - - - - - - - - - - 1

You have a budget of 40$. Fruit cost 4$ per pound and the granola bars cost 1$ each. This means that

4x + y = 40

Substituting y = 40 - 4x into equation 1, it becomes

x + 40 - 4x ≥ 20

x - 4x ≥ 20 - 40

- 3x ≥ - 20

Dividing both sides of the equation by - 1, it becomes

3x ≤ 20

x ≤ 20/3 = 6.67

This means that the maximum number of pounds of fruit that you can by is 6 pounds.

Therefore the combination of fruit and granola bars that you can buy would be

1) 6 pounds of fruit and 16 bars of granola.

2) 5 pounds of fruit and 20 bars of granola.

3) 4 pounds of fruit and 24 bars of granola.

4) 3 pounds of fruit and 28 bars of granola.

5) 2 pounds of fruit and 32 bars of granola.

6) 1 pound of fruit and 36 bars of granola.
