Your answer would be option B. 2y² - y - 6 = 0. This is because if you were to substitute x = y² - 1 into the equation 2x - y = 4, you would get 2(y² - 1) - y = 4, which expands into 2y² - 2 - y = 4, and then simplifies to 2y² - y - 6 = 0.
I hope this helps!
Answer:
Your answer is D.
36x2-25 is equivalent to (6x)2-(5)2
Step-by-step explanation:
Simple solution: Put each equation into a graphing calculator and look at the tables, they are exactly the same.
The following sequence shown up top is arithmetic sequence
#7 is the easiest one.
a + bi = -9 + 4i
see the expression on either side matches up so..
a = -9 and b = 4
Answer:
i think the answer is 19x^-2x+2
