2xy=2*30*2=120
2xy substitute 3 for y and 5 for x 2(5)(3) = 30
15xy-2xy-7x+x=13xy-6x
No, it equals -2xy. lrn2math
Put in this form. Y =mX + c4Y - 2X = 04Y = 2XY = (1/2)X============so,X = 2Y = 1X = 4Y = 2X = - 2Y = - 1=============(2, 1)....(4, 2)......(- 2, - 1)---------------------------------------three points on that line
It's an hyperbola equation.
Because 2x+y is addition not multiplication
Y=15/(2c+2x)
x2 + y2 = x2 - 2xy + y2 + 2xy = (x - y)2 + 2xy = 72 + 2*8 = 49 + 16 = 65 You could, instead, solve the two equations for x and y and substitute, but the above method is simpler.
2xy*9 if x=3 and y = 2 2(3)(2)*9 12*9 108 You substitute x and y for their equivalent (3 and 2) then simply multiply 2*x*y, then multiply the answer of that by 9.
Since 2xy is a factor of 2x2y, it is automatically the GCF.
L = 3x + 2y
