Answer:
C)The independent variable is time, and the dependent variable is distance.
The distance covered is dependent on the time.
Answer:
The minimum value = -38
Step-by-step explanation:
∵ f(x) = x² - 12x - 2
∵ -12x ÷ 2 = -6x ⇒ -6 × x
∴ (x - 6)² = x² - 12x + 36
∴ Add and subtract 36 in f(x)
∴ f(x) = (x² - 12x + 36) - 36 - 2
∴ f(x) = (x - 6)² - 38 ⇒ completing square
∴ The vertex of the parabola is (6 , -38)
∵ Its minimum point because the coefficient of x² is positive
∴ The minimum value = -38
Answer:
17 units
Step-by-step explanation:
P to Q = (-2,2) to (5,2) = is 7 units
The Q to R = (5,2) to (5,-5) is 7 units
Then R so S = (5,-5) to (8,-5) is 3 units
7+7+3 = 17 units
70,000,000 + 00,000,000 + 0,000,000 + 000,000 + 00,000 + 0,000 + 000 + 00 + 0
Answer:
She has 20 coins in her bank, where she has 12 nickels and 8 quarters
Step-by-step explanation:
- A nickel is 5 cents
- Since she has 8 fewer than nickels, we add 8 to the number of nickels
Q = N + 8, 25Q + 5N = 560
25(N + 8) + 5N = 560
25N + 200 + 5N = 560
25N + 200 - 200 + 5N = 560 - 200
30N = 360
30N / 30 = 360 / 30
N = 12 nickels
Finding amount of Quarters:
Q = N + 8 → Q = 12 + 8
Q = 20 quarters
