9y2+66y+121 = (3y+11)(3y+11) when factored
This statement is already nearly factored. The best we can do is pull out the 9 from each term:9x + 9y + 72 = 9(x + y + 8)
It is 9y - 10. This is an expression which cannot be simplified and, since it is not an equation, it cannot be solved.
-7x+9y = 54 9y = 7x+54 y = 7/9x+6 which is now in slope-intercept form
(y - 2)(y - 7)
It is equivalent to 3(4x+3y) when factored
9y2+66y+121 = (3y+11)(3y+11) when factored
This statement is already nearly factored. The best we can do is pull out the 9 from each term:9x + 9y + 72 = 9(x + y + 8)
The following is the answer.
It is 9y - 10. This is an expression which cannot be simplified and, since it is not an equation, it cannot be solved.
-4y
-3x+9y = 6 9y = 3x+6 y = 1/3x+2/3
9 + 9y = 27x -9 -9 9y = 27x - 9 9y/9 = 27x/9 - 9/9 y = 3x -1
9y - 4x
-7x+9y = 54 9y = 7x+54 y = 7/9x+6 which is now in slope-intercept form
9y subtract 11 equals 7
(y - 2)(y - 7)
