Answer:

-2x^2-3x-4

Step-by-step explanation:

We have to simplify the expression (x^2-8x+5)+(-3x^2+5x-9)

Distribute the positive sign over the parenthesis

x^2-8x+5-3x^2+5x-9

Combine the like terms

-2x^2-3x-4

Therefore, the expression after simplification is -2x^2-3x-4

Second option is correct.

Answer:

Part A: 4,300 ≥ 2500 + 0.12s

Part B: Less than or equal to $15,000

Part C: In the image

Step-by-step explanation:

For Part A: The total needs to be at least 4,300. So 4,300 is greater than or equal to how much she earns. 2,500 is the base pay, and it is added to 0.12s, which represents 12% of sales (s).

For Part B:

Using the inequality, solve for s

4,300 ≥ 2500 + 0.12s

Subtract 2500 from both sides

1800 ≥ 0.12s

Now divide both sides by 0.12 to isolate s

15000 ≥ s

So sales must be less than or equal to 15000.

Part C:
