Answer:
120 ways
Step-by-step explanation:
To solve the question above, we use combination formula:
Where ;
nCr = n! / (n-r)! r!
10C7 = 10! / (10 - 7)! 7!
10C7 = 10! / 3! 7!
10C7 = (10 * 9 * 8) / 3 * 2 * 1
10C7 = 720 / 6
= 120 ways
Answer:
x = - 130.5
Step-by-step explanation:
2x + 5 + 256
2x = -261
x = - 130.5
Tell me if I am wrong.

Remember that if f and g are inverses of one another, then
f(g(x)) = g(f(x)) = x
1/2. Take a = 0 and b = 1 (or any non-zero number) so that
f(x) = x + 0/1 ⇒ f(x) = x
If g is to be an inverse of f, we need
g(f(x)) = g(x) = x
so that c = 1 and d = 0.
3. With f(x) = x + a/b and g(x) = cx - d, we have
g(f(x)) = g(x + a/b) = c (x + a/b) - d = cx + ac/b - d
and of course, with a,b,c,d as before, we get g(f(x)) = x.
4. This would be a very uninteresting graph for the example I've cooked up here, just containing the line y = x...
1 foot 2 inches
With 8 wreaths, each taking a foot, 1 ft 4 in is left over.
There are 12 inches in a foot, so 12 + 4 = 16 inches of,ribbon left.
16inches / 8 wreaths, gives 2 extra inches per wreath.
Or, convert alll to inches.
(9*12) + 4 = 108 + 4 = 112 inches of ribbon
112/8=14 inches of ribbon. Or 1 ft 2 inches of ribbon for each wreath
