2 cos cube A - cos A
•
(-9, 3) is a solution to the equation.
(2, - 4) is a solution to the equation.
Neither ordered pair is a solution.
Both ordered pairs are solutions.
Answer:
(2, - 4) is a solution to the equation
Step-by-step explanation:
Substitute the x and y coordinates of the points into the left side of the equation and if equal to the right side then they are a solution.
(- 9, 3 )
6(- 9) -
= - 54 - 1.5 = - 55.5 ≠ 14 ← not a solution
(2, - 4)
6(2) -
= 12 + 2 = 14 ← This is a solution
Thus (2, - 4) is a solution to the equation
