The inverse functions have a property that the composition of two inverse functions always results is x.
From the given options, only the pair given in option B result in the composition equal to x.
This proves, F(x) and G(x) are inverse of each other.
So the answer to this question is Option B
Judging by the model I would assume that ΔDBC is congruent to ΔDBA.
Thus, line CD should be congruent to line AD as well, which the solution should be line CD=13 units.
1. Distributive Property on the left side
2x-24=5x+9
2. Subtract 9 from the right side and do the same on the left side
2x-33=5x
3. Subtract 2x from both left and right sides
-33=3x
4. Divide 3 from Borge left and right sides
-11=x
Answer: x = -11
8x - 3x - 7 = 23
5x - 7 = 23
5x = 30
x = 30/5 = 6
Answer:
The length of side along the river is 68 m
Step-by-step explanation:
Area of trapezium = 10200 m²
Length of side along the road (a) = x
Length of side along the river (b) = 2x
Height = 200 m
We need to find Length of side along the river.
The formula used is:
Putting values and finding length:
So, Value of x = 34
Length of side along the road (a) = x = 34
Length of side along the river (b) = 2x = 2(34) = 68
So, the length of side along the river is 68 m
