<span>We want to show that f(g(x)) = x and g(f(x)) = x.
So to do that, we need to calculate f(g(x)) and g(f(x)) explicitly.
Let's begin with f(g(x))
Now, f(g(x)) = f(4/x), by definition of g, as g(x) = 4/x
What then is f(4/x) equal to? Use the definition of f.</span>
Answer:
6.96cm^2
Step-by-step explanation:
Area of triangle:
Base*height/2
5.8*2.4/2
Area = 6.96cm^2
Answer: 1. 
<----(answer for 7 x 10 - 8)
2. 
<---- (answer for 2 x 10-8)
Step-by-step explanation:
You see one point is (-3,1). The next point that you see is (0,2). You can do rise/run
For 1 to go to 2, you need to go up one. For -3 to get to 0, you need to run 3. So, the answer would be rise/run, or
1/3
Answer:
A. x = 8.
B. x = 31.
C. x = 32.
Step-by-step explanation:
Here. the sum of the 2 parallel sides of the trapezoid = 2 * length of the middle line segment.
MN + RS = 2PQ
32+ x = 2*20
x = 40 - 32
x = 8.
MN + RS = 2PQ
20 + 42 = 2PQ
2x = 62
x = 31
MN + RS = 2PQ
22 + 42 = 2PQ
2x = 64
x = 32.
