Answer:
C. 
Step-by-step explanation:
Iterative geometric sequence:

Recursive geometric sequence:

The equations are very similar and you only really need to rearrange it. The factor (2/3) and the first term (9) are given, so you can write the iterative equation:

And so the answer is C.
Answer:
x = -8
y = 9
Step-by-step explanation:
to solve this expression using simultaneous equation, we would say let
y =9............................................. equation 1
6x + 5y =-3............................................equation 2
substitute equation 1 into equation 2
-3 = 6x + 5y............................................equation 2
6x + 5(9) = -3
6x + 45 = -3
collect the like terms
6x = -3-45
6x = -48
divide both sides by the coefficient of x which is 6
6x/6 = -48/6
x = -8
therefore y = 9
x = -8
The equation would look like: p - 5.16 = 15.48
because the coupon subtracts 5.16 from p and the price you pay is 15.48
Solve the equation by adding 5.16 to both sides
p = 20.64
The original price of the shirt is $20.64
Step-by-step explanation:

Replace x and y.

Solve for y.

Square both sides.


This is the inverse function or you can also say
