It doesn't make much sense to calculate logarithms with pencil and paper - the calculations are too involved. Just multiply the two numbers, and calculate the logarithm on a scientific calculator. If you don't have one, use the Windows calculator (it has a mode for scientific calculator).

What are the coordinated when x-2y equals 8 intersects with xy equals 24?
The coordinates are: (-4, -6) and (12, 2)
Write this in the form of single logarithm log x plus log y?
That is the same as log xy.

That is the same as log xy.
If xy equals x or yx equals x what is y?
xy = x ÷x y = 1
If xy plus y equals z then x equals?
xy + y = z xy = z - y (xy)/y = (z - y)/y x = (z - y)/y
What is the property for xy equals 1 xy?
That is the commutative property of equality.
If xz plus zy equals xy and xz equals zy then the point z is?
mid point of xy
What is xy-2 when x equals 5 and y equals 4?
18
X plus XY equals 8 solve for Y?
x+xy=8 xy=-x+8 y=-1+8/x
What are the coordinates of the points of intersection of x-2y equals 8 and xy equals 24?
Using: x - 2y = 8 y = (x - 8)/2 Substituting in: xy = 24 => x(x - 8)/2 = 24 => x2 - 8x = 48 => x2 - 8x - 48 = 0 => (x - 12)(x + 4) = 0 => x = 12 or -4 => y = 2 or -6 respectively (since xy = 24) ie the points (12, 2) and (-4, -6)
What is the answer to 2x plus 2y equals 42 and xy equals 104?
Given: 2X + 2Y = 42X + Y = 42/2X + Y = 211 + 20 =212 + 19 =213 + 18 =214 + 17 =215 + 16 =216 + 15 =217 + 14 =218 + 13 =219 + 12 =2110 + 11 =21Given: XY = 1048 x 13 = 104X=8, 13Y=13, 8
Is xy equals 7 a inverse relation?
Yes.
