The answer should be 5 or -5
Simple actually. The 1000 is the starting price the -20 is the losing of value per week and the w stands for the number of weeks.
Step-by-step explanation:
hence the value of y=-9/4and k=-16.
Sum of interior angles of a △ = 180°
∴ ∠T + ∠V + ∠U = 180°
⇒ 37° + 63° + X° = 180°
⇒ X° + 100 = 180°
⇒ X° = 180° - 100°
⇒ X° = 80° (D).
