As you can see, in the table of the first function, f(2) = 18, and in the table of the second function g(2) = 18. Then, for x = 2, f(x) = g(x). and x =2 is the solution of the equation.
Answer: x = 2.
Answer:
Your rule is: Multiply 2, Add 1
Step-by-step explanation:
Check:
2 x 2 = 4 + 1 = 5
5 x 2 = 10 + 1 = 11
11 x 2 = 22 + 1 = 23
23 x 2 = 46 + 1 = 47

Step-by-step explanation:
i cant be simplified
Let the price of the 3rd card be c. Now we can write the equation:
c + (c + 20) + (c + c + 20) = 160 .........(1)
Simplifying the left hand side of equation (1), we get:
4c + 40 = 160 .........(2)
Subtracting 40 from both sides of equation (2) gives:
4c = 120
from which c = $30.
Therefore the price of the second card = 30 + 20 = $50
and the price of the first card = 30 + 50 = $80.
