The function f(x) varies inversely with x and f(x)=0.5 when x = 0.3. What is f(x) when x = 2.4? A)5.76 B)0.0625 C)0.30 D)0.15
1 answer:
Answer:
B) 0.0625
Step-by-step explanation:
f(x) = k / x
f(x)=0.5 when x = 0.3
f(x) = k / x
0.5 = k / 0.3
Cross product
0.5 * 0.3 = k
k = 0.15
What is f(x) when x = 2.4?
f(x) = k / x
f(x) = 0.15 / 2.4
f(x) = 0.0625
The answer is B) 0.0625

Hope this helps I got (-1, 7)
Answer:
i do not know what you are talking about. I see no question...
Answer:
2b - 15 > 21
add 15 to both sides:
2b-15+15 > 21 + 15
2b > 36
Divide both sides by 2 :
2b/2 > 36/2
2b = 36
b = 36 / 2
b > 18
hope this helps!
