<span>System 1 and system 2, because the second equation in system 2 is obtained by adding the first equation in system 1 to two times the second equation in system 1
This is the correct answer because not only is it true but it also follows the property of solving systems of equations with adding the equations. To prove that it is true:
2nd equation in system #2 = 1st equation in system #1 + 2(2nd equation in system #1)
</span>10x − 7y = 18 == 4x − 5y = 2 + 2(<span>3x − y = 8)
10x - 7y = 18 == 4x - 5y = 2 + 6x - 2y = 16
10x = 7y = 18 == 10x - 7y = 18</span>
23/40 can't be simplified as it has no common factors
Answer: 2
Step-by-step explanation:
Use desmos!
Answer: The answer is the first choice.
Explanation:
Because you must find the sin of the x values in the table.
Sin(7pi/6) = -1/2
Sin(5pi/4) = -sqrt 2/2
Sin(4pi/3) = -sqrt 3/2
