Answer:
f(-1) = -4
Step-by-step explanation:
f(-1) simply means that what is f(x) when x = -1?
Just plug in -1 for <em>x</em> to find your answer:
f(-1) = -3(-1) + 2(-1) - 5
f(-1) = 3 - 2 - 5
f(-1) = 1 - 5
f(-1) = -4
Let x be the number of minutes of 5.8*10^6 seconds.
Each minute is made of 60 seconds. Let's then use the rule of three:
60 seconds --> 1 minute
5.8*10^6 --> x minutes
x = (5.8*10^6)*1 / 60
x ≈ 96,666.66 minutes.
So 5.8*10^6 seconds is about 96,666.66 minutes.
Hope this Helps! :)
