Answer: v= -10/7
Explanation: Simply both sides of the equation then isolate the variable.
Answer:
B.
Step-by-step explanation:
Point estimate is always at the center of the interval.
You can find it by averaging the endpoints:
p(hat) = (0.028 + 0.086)/2 = 0.057
F(x) = x² + x - 20 = x² + 5x - 4x - 20 = x(x + 5) - 4(x + 5) = (x + 5)(x - 4)
f(x) = 0 ⇔ (x + 5)(x - 4) = 0 ⇔ x + 5 = 0 or x - 4 = 0 ⇒ x = -5 or x = 4
Answer: C. x = -5 and x = 4.
