Answer:
C and D
Step-by-step explanation:
To determine which pairs are solutions, substitute the coordinates into the left side of the equation and if equal to the right side then they are solutions.
(7, - 2)
2(7) + 10(- 2) = 14 - 20 = - 6 ≠ 12 → (7, - 2) is not a solution
(- 5, - 4)
2(- 5) + 10(- 4) = - 10 - 40 = - 50 ≠ 12 → (- 5, - 4) is not a solution
(4, )
2(4) + 10() = 8 + 4 = 12 → hence solution
(- 5, )
2(- 5) + 10( ) = - 10 + 22 = 12 → hence solution
<u>Answer:</u>
The net price of the product is $1445.
<u>Solution:</u>
Given, regular price of a product is $1500 and it has a discount at the rate of 3%
We have to find the final price of the product.
We know that, <em>final product of price = regular price – discount price </em>
Final price of product = 1500 – 3% of 1500
Final price of product
= 1500 – 3 15 = 1500 – 45
Final price = 1455
Hence, the net price of the product is $1445.
