It is 236.39. Explanation if Margo is driving 61.4 miles per hour he will go that many miles an hour, tip (don't think of it as speed in math). If 3.85 hours pass multiply that against 61.4 miles an hour. Getting you 236.39. Here is an explanation. His amount of distance he covers per hour is 61.4 so every hour that number adds up and to get this just multiply against 3.85 hours. Do you get it now?
Answer:
B
Step-by-step explanation:
Given the 2 equations
x³ + y = 0 → (1)
11x² - y = 0 → (2)
Add (1) and (2) term by term to eliminate the term in y
x³ + 11x² = 0 ← factor out x² from each term
x²(x + 11) = 0
Equate each factor to zero and solve for x
x² = 0 ⇒ x = 0
x + 11 = 0 ⇒ x = - 11
Substitute these values into (1) for corresponding values of y
(1) y = - x³
x = 0 ⇒ y = 0 ⇒ (0, 0) is a solution
x = - 11 ⇒ y = - (- 11)³ = 1331 ⇒ (- 11, 1331) is a solution
The correct answer is 0.09
