Answer:
(7, 5) no
(-6, -3) yes
(-5, 2) no
(1, -4) no
Step-by-step explanation:
For this question we have to input the x and y values into the equation: 2x - 9y = 15
For (7, 5) we would get 14 - 45 = 15 which is false so it is not a solution.
For (-6, -3) we would get -12 + 27 = 15 which is true so it is a solution.
For (-5, 2) we would get -10 - 18 = 15 which is false so it is not a solution.
For (1, -4) we would get 2 + 36 = 15 which is false so it is not a solution.
The question ask to complete the question that ask to calculate the total purchase price of on-sale item with a 6% sales tax and the answer would be letter D. Add the sales prices and multiply by 1.06. I hope you are satisfied with my answer and feel free to ask for more
Answer:
16π cm²
Step-by-step explanation:
We know that
Circumference = 2πr
=> 8π = 2πr
=> 8 = 2r
=> 8/2 = r
=> 4 = r
Now,
Area of circle = πr²
=> π × (4)²
=> π × 16
=> 16π cm²
