Eliminate the y’s via elimination (subtract both of the equations):
x^2 - x = 6
x^2 - x - 6 = 0
Factor the quadratic:
(x - 3)(x + 2) = 0
Set each equation equal to 0 and solve.
x - 3 = 0 , x + 2 = 0
x = 3 , x = -2
Plug in the 1st value for x into the second equation:
3 - y = -3
-y = -6
y = 6
Plug in the second value for x into the second equation:
-2 - y = -3
-y = -1
y = 1

The recursive formula of h(n) is h(1) = 36 and h(n) = h(n -1) - 5
<h3>How to determine the recursive formula?</h3>
The function is given as:
h(n) = 41- 5n
Calculate h(1) and h(2)
h(1) = 41- 5(1)
h(1) = 36
h(2) = 41- 5(2)
h(2) = 31
Calculate the difference between h(1) and h(2)
d = 31 - 36
d = -5
This means that:
h(1) = 36 and h(n) = h(n -1) - 5
Hence, the recursive formula of h(n) is h(1) = 36 and h(n) = h(n -1) - 5

Answer:
B.) 166
Step-by-step explanation:
10 x 2 = 20
12 x 10 = 120
13 x 2 = 26
20 + 120 + 26 = 166
