Find f(x) and g(x) so the function can be expressed as y = f(g(x)) y = Seven divided by x squared. + 10
Answers
g(x)=x²+10
Then f(g(x))= 7/(x²+10)
By the way g(f(x))=(7/x)² + 10
Answer:
- f(x) =
+ 10
- g(x) =
Step-by-step explanation:
Given that:
y = f(g(x)) = + 10
It is obviously that g(x) is put as an independent variable of f(x) to have the equation of y written above.
So
- f(x) =
- g(x) =

The slope from point O to point A is one-half times the slope of the line from point A to point B. The slope from point O to point A is two times the slope of the line from point A to point B.
Answers
Answer:
The slope is fraction negative 1 over 2 throughout the line.
Step-by-step explanation:
The slope (m) of a line is computed as follows
m = (y2 - y1)/(x2 -x1)
where (x1, y1) and (x2, y2) are the coordinates of 2 points of the line. Taking, for example, points (0, 0) and (-4, 2), the slope is:
m = (2 - 0)/(-4 -0) = -1/2
Then, the slope is -1/2 throughout the line.

If it's NOT a right triangle, then no answer is possible.
I'm going to assume that it's a right triangle, because you did say
that one 'leg' is 12, and you want the length of the other 'leg'. It's
common to refer to the two short sides of a right triangle as 'legs'.
In "Tales of Pythagoras", we learned that in a right triangle ...
(Longest side)² = (one leg)² + (the other leg)²
In your triangle ...
(20)² = (12)² + (the other leg)²
(400) = (144) + (the other leg)²
Subtract 144 from each side: (The other leg)² = (400 - 144) = 256
The other leg = √256 = 16 .
