Answer:
The constant of proportionality is k=1/4
Step-by-step explanation:
For the equation y=kx, y varies directly with x with the constant of proportionality k. Therefore, k=1/4 is the answer.

Answer:
(a) 2 (17 + 8)
Step-by-step explanation:
The largest common factor is 2.
34 +16 = 2·17 +2·8 = 2(17 +8)
Answer: the coomon factor that is missing from both sets of parentheses is 2x + 7.
Explanation:
These are the steps to factor the polynomial with the reasons that justify them:
Step Reason
1. 10x³ + 35x² - 4x - 14 Given
2. (10x³ + 35x²) - (4x + 14) Group the terms
3. 5x² (2x + 7) - 2 (2x + 7) Common factor 5x² and 2
After this, you extract common factor 2x + 7 and have the complete factored polynomial: (2x + 7) (5x² - 2).
130 per hour and 3 hours. 390km, 130 x 3 = 390.
