I could only answer 14. and it is 138.3
Answer:
550 + 3x > 1000, where x > 150
The quantities true for x are: x must be greater than 150
Step-by-step explanation:
The question claims he wants to earn OVER 1,000 that month. He already makes $550 and $3 PER PLANT he sells. Subtract $550 from $1000 and you would get 450. Then divide by 3. That makes 150 plants. So now we know the x needs to be GREATER THAN 150 plants to make over 1,000. The x would also go next to the 3 because the 3 represents how much per plant sold, and the 150 represents how many plants. The equation would be $550 + 3x > 1000, where x > 150.

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2/3x² + 8
f(6) is x = 6
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(6) = 2/3(6)² + 8
- Exponents: f(6) = 2/3(36) + 8
- Multiply: f(6) = 24 + 8
- Add: f(6) = 32
Answer:
m ∠ABD = 140°
m ∠DBC = 40°
Step-by-step explanation:
∠ (15x - 4) + ∠(5x - 8) = 180°
15x - 4 + 5x - 8 = 180
20x -1 2 = 180
20x = 180 + 12
x = 9.6
m ∠ABD = 15x - 4 = 140°
m ∠DBC = 5x - 8 = 40°
