Instead of X put 5 and instead of y put 2
5+6(2)
5+12= 17
3+8x-2y-x+1+4y
Combine all like terms and
7x+4+2y is your answer
Answer: 3.87132498658 in other words 3.871
Step-by-step explanation:
The answer is $37,923
<span>y = 844.697x^2 + 3723.485x - 13,650
x - number of years
y - the annual profit
If x = 8, the annual profit y is:
y = </span>844.697 * 8^2 + 3723.485 * 8 - 13,650
y = 844.697 * 64 + 29,787.88 - 13,650
y = 54,060.608 + 16,137.88
y = 37,922.728 ≈ 37,923
