Answer:
x = 5/2 = 2.5
Step-by-step explanation:
Given
f(x) = 3x-7
g(x) = x+2
g^(-1)(x) = f(x)
First find g^(-1)(x) = h(x)
x=h(x)+2
h(x) = x -2
h(x) = x - 2 = f(x) = 3x-7
solve for x
x-2 = 3x -7
-2 + 7 = 3x - x
2x = 5
x = 5/2
There are 26 possible lowercase letters, 26 possible uppercase letters, and 10 possible numbers (0-9).
26+26+10=62
That means there's a 1/62 chance that they get one letter right.
But there's 15 letters.
They're chance would decrease each time to get it exact.
1/62 divided by 15/1 =
1/832
So there is a 1 in 832 chance that the hacker guesses it correct first try with that information.
The cold war came to an end
He is incorrect because you can multiply unlike terms like y and x and you'll get xy but you can't add unlike terms like 13x+16y is the simplest it can be.
The nearest whole number to the number 5.2 is 5.
Given number:
= 5.2
we can determine the whole number of any decimals using the properties that is,
if decimal part < .5 its nearest whole number is 0.
example = 0.5 whole number is 0.
if decimal part > 0.5 its nearest whole number is 1.
In this case,
= 5.2
decimal part = 0.2 < 0
so the nearest whole number is 5.
Therefore the nearest whole number to the number 5.2 is 5.
