5y - 65xy '5' is a common factor both numbers. Hence 'take it out'. 5(y - 13xy) 'y' is a common factor to both terms, so take it out too!!!! 5y(1 - 13x) Done Factored!!!!!
The GCF is 5y.20y3 = (5y)(4y2)5y2 = (5y)(y)45y = (5y)(9)
Assuming the missing operational sign are pluses, that factors to (3x + 5)(y + 2)
2(x - 5y)
Remember both 16 & 25 are squared numbers. 16 = 4^2 & 25 = 5^2 Hence we can write (4x)^2 - (5y)^2 Remember two squared terms with a NEGATIVE Between them will factor. ( 4x - 5y)(4x + 5y) Note the difference signs. NNB Two squared terms with a positive (+) between them DOES NOT factor.
15x-20y= 7 5y-3 +10x
-10
-120
Oh honey, you're in for a treat. The expression 10x - 25y can be simplified using the greatest common factor, which in this case is 5. So, you can rewrite it as 5(2x - 5y). Voila! That's the sassy math lesson of the day.
(5y - 2)(5y + 2)
5y - 65xy '5' is a common factor both numbers. Hence 'take it out'. 5(y - 13xy) 'y' is a common factor to both terms, so take it out too!!!! 5y(1 - 13x) Done Factored!!!!!
The GCF is 5y.20y3 = (5y)(4y2)5y2 = (5y)(y)45y = (5y)(9)
5y = 15x -45 Divide by 5 y = 15x/5 -45/5 y = 3x -9 y = mx + b m= 3 6 = -9 The slope is 3 The y intercept is -9
This is simply a set of algebraic expressions which has no simpler form. Perhaps there should be an equals sign somewhere.
2x-5y = -10 -5y = -2x-10 y = 2/5x+2 which is in slope intercept form
(5y + 7w)(5y - 7w)
8 + 5y = 18 Therefore, 5y = 10 y = 10/5 y = 2
