Yes, because 1/4 plus 1/4 equals 2/4 (or 1/2) and 3/4-2/4 equals 1/4.
It is 3 73/99
I just used a fraction calculator lol
9x² - 49
(3x)² - (7)²
= (3x + 7)(3x - 7)
This type of factoring is called Difference of Two Squares
where x² - y² = (x + y)(x - y)
Answer:
Step-by-step explanation:
-2x+y=4
-2(1)+2=4
-2+2=0, not 4.
Therefore, (1, 2) is not a solution to this equation.
