Answer:
x - y = 3
any values of x& y where x is three greater than y
I.E. x = 8 y = 5
Step-by-step explanation:
Answer:
336
Step-by-step explanation:
Required Formulas:-
1. Number of ways to select x things out of n things = ⁿCₓ
2. Number of ways to arrange n things when a things and b things are similar = n!/(a!*b!)
Since we have to choose 8 colors and we are having 3 different colors, it is only possible when we select 2 different colors (e.g. 5 red and 3 blue). To find all possible ways we will have to find all unique arrangements of selected color.
Using formula (1), number of ways to select 2 colors out of given 3 colors = ³C₂ = 3
Using formula (2), finding all unique arrangements when 5 stripes are of one color and 3 stripes are of second color = 8!/(3!*5!) = 56
Suppose, we can choose 5 stripes from red color and 3 stripes from blue color or 5 strips from blue color and 3 strips from red color. So there are 2 possibilities of arranging every 2 colors we choose .
∴ Answer=3*56*2 = 336
Multiply both sides by any number you want. I'll pick 2
x = -3 turns into 2x = -6 after doing so
--------------------------
Add anything you want to both sides. I'll pick 7
x = -3 turns into x+7 = 4 after doing so
---------------------------
you can do a combination of both multiplication and addition, as long as you do the same thing to both sides. First I'll do multiplication. I'm going to multiply both sides by 2 first
x = -3 turns into 2x = -6
then I'm going to add 7 to both sides
2x = -6 turns into 2x+7 = 1
If you were to solve 2x+7 = -1, then you'd get to x = -3 again
As a check, replace x with -3 and we have...
2x+7 = 1
2(-3)+7 = 1
-6+7 = 1
1 = 1
we get a true statement, which helps confirm we have the right equation.
Answer:
g - 1
Step-by-step explanation:
g - 2/2
2/2 = 1
g - 1
It's the function of function: f(g(x))
1st you replace x (of f(x) by the value of g(x)
Example: let's take f(x) = x² ag g(x) = 1/x, you just plug 1/x into x in f(x)
f(g(x)) = f(1/x)² & f(x) =1/x²
If we follow the same methodology we find that f(x) =2/x & g(x) =2/x is the answer to the problem. Proof:
f(g(x)) = f( 2/(2/x)) = f(2(x/2) =2x/2 = x
