Answer:
9
Step-by-step explanation:
18 + 45 = 63
9 x (2+5) = 9 x 7 = 63
The answer to this question is 640,000
Solving for Y:
1) Subtract -2x from both sides: -3y=15-2x
2) Divide by -3 on both sides: y=-5+(2/3)x
Final Answer: y = (2/3)x-5
Say b, initial price, + 20,000.
y, price after x years = m years + 20,000.
m would be negative because the price would decline after x years.
