because this equation has 2 variables, each variable won't have an exact answer.
this equation will make a nice line graph though, this is how to put it in that format.
2x-y=9
add y to both sides
2x=9+y
subtract 9 from both sides
y=2x-9
now you can graph it. it has a slope of 2 and a y intersect of -9
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.
2xy=2*30*2=120
15xy-2xy-7x+x=13xy-6x
√18xy = √(9*2xy) = √9*√2xy = 3*√(2xy)
No, it equals -2xy. lrn2math

2xy=2*30*2=120
2xy substitute 3 for y and 5 for x 2(5)(3) = 30
15xy-2xy-7x+x=13xy-6x
√18xy = √(9*2xy) = √9*√2xy = 3*√(2xy)
No, it equals -2xy. lrn2math
It's an hyperbola equation.
Y=15/(2c+2x)
Because 2x+y is addition not multiplication
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.
Since 2xy is a factor of 2x2y, it is automatically the GCF.
L = 3x + 2y
