Answer:
1. $250,000× 6,5%= $16,250
$310,000×6,5% = $20,150
therefore $16,250+$20,150=$21,800

991,000 times ×$1,09×15% = $162,028.5
Step-by-step explanation:
3. $8,870×25%=$2217,50
The answer is 16 because 16+2=18-4=14
Dy/dx = dy/dt / dx/dt
dy/dx = 12x^2 + 4
when x = 2 , dydx = 52
52 = dy/dt / 3
so dy/dt = 156 (answer)
-4x^2 - 8......input (x) = 2
-4(2^2) - 8 =
-4(4) - 8 =
-16 - 8 =
- 24 <==
x = 1 because -7(3x + 4) must be -49 so 3x + 4 must me 7 so x = 1
