Answer:
A
Step-by-step explanation:
Given the 2 equations
x = 3 - y → (1)
5x - 12 = y → (2)
Substitute x = 3 - y into (2)
5(3 - y) - 12 = y ← distribute and simplify left side
15 - 5y - 12 = y
3 - 5y = y ( add 5y to both sides )
3 = 6y ( divide both sides by 6 )
= y, that is
y = 0.5 → A
exponential growth is your answer. If it is not a negative then it wont be exponential decay. if it is a positive then it is growth
Answer:
480
Step-by-step explanation:
Sn = n÷2 × (2a + (n-1)d)
