Answer:
(- 6, 0 )
Step-by-step explanation:
Given the 2 equations
3x + 2y = - 18 → (1)
2x + 9y = - 12 → (2)
Multiplying (1) by 2 and (2) by - 3 and adding will eliminate the term in x, that is
6x + 4y = - 36 → (3)
- 6x - 27y = 36 → (4)
Add (3) and (4) term by term to eliminate x
- 23y = 0
y = 0
Substitute y = 0 into either of the 2 equations and evaluate for x
Substituting into (1)
3x + 0 = - 18
3x = - 18 ( divide both sides by 3 )
x = - 6
Solution is (- 6, 0 )
Let x represent the cost of the movie ticket and y represent the cost of a snack item.
3x + 3y
Answer:
The value of f(3) is -2.
Step-by-step explanation:
This is a recursive function. So
Now, we find f(2) in function of f(1). So
Now, with f(2), we can find the value of f(3).
The value of f(3) is -2.
X and y would be 1/1 or 1
