Answer:
$16,500
Step-by-step explanation:
The computation of the amount that should be paid for the car is shown below:
Since the car would be purchased one year ago
And, the value of the car would be decreased by 15% to $14025
So the amount that should be paid is
= $14025 × 100 ÷ (100 - 0.15)
= $16,500
Answer:
i). x³ + 9x² + yz - 15
ii). -21m³np - 8p⁵q + mnp + 4mn + 100
Step-by-step explanation:
Question (38)
i). Two expressions are -5x² - 4yz + 15 and x³+ 4x²- 3yz
By subtracting expression (1) from expression (2) we can the expression by addition which we can get expression (1).
(x³+ 4x²- 3yz) - (-5x² - 4yz + 15) = x³ + 4x² - 3yz + 5x² + 4yz - 15
= x³ + 9x² + yz - 15
ii). -15m³np + 2p⁵q - 6m³pn + mnp + 4mn - 10qp⁵+ 100
= (-15m³np - 6m³np) + (2p⁵q - 10qp⁵) + mnp + 4mn + 100
= -21m³np - 8p⁵q + mnp + 4mn + 100
The formula of a slope:

We have the points (1, 4) and (1, -3). Substitute:

DIVISION BY ZERO!!!
Answer: The slope is undefined.
It's a vertical line x = 1.
