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
Answer:
6776
Step-by-step explanation:
77
88
-----
8 times 7=56 8 times 70= 560 then add together so 616 next line 80 times 7= 560 80 times 70=5600 then add those together 6160 then add the too totals together 6160+ 616= 6776
The coordinates of x are (1.6, 1.2).
Solution:
Given points of the line segment are A(0, 0) and B(4, 3)
X be the point divided the line segment AB in the distance .
i.e., in the ratio of 2 : 3.
Section formula:
Here, and m = 2, n = 3
Substitute these in the section formula,
<em>X(x, y)</em> = (1.6, 1.2)
The coordinates of x are (1.6, 1.2).
To find this number, let's represent the unknown amount of students with the variable x:
356 + 365 + x = 977
721 + x = 977
x = 256
There are 256 students in ninth grade.
18x+6y = 6(3x+y)
