Answer:
For what value of x is f/x 4?
Answer: f (x) = 4 occurs when x = 0 and f (-2) = 2.
Answer:
(V + W) * 5 = 175 boat traveling downstream
(V - W) * 7 = 189 boat traveling upstream
V + W = 35
V - W = 27
2 V = 62
V = 31 = speed of boat
2 W = 8
W = 4 speed of water
Upstream 7 * (31 - 4) = 189
Downstream 5 * (31 + 4) = 175
They create proofs in mathematics and science and are often the basic truth of a much larger theory or law. They themselves cannot be proven.
Answer:
First prime factorize the number:
25 = 5 × 5
75 = 3 × 5 × 5
Then find the GCF:
GCF(25, 75)
= 5 × 5
= 25
A is your answer hope this helps
