AX plus BY equals AY plus BX what is the general equation?
Assuming the question is about chemical reactions (rather than mathematics where it is placed), it is a double displacement.
A vector A has components Ax 11 m and Ay 43 m What is the the angle that vector A makes with the x-axis?
Theata = Tan^-1(Ay/Ax) Theata = 75.7 deg
One way to find the equation of a line is to look at some points on it and try to find the relationship between the coordinates?
Yes. You need only two points. If A (ax, ay) and B (bx, by) are two points on the line then the gradient (slope) of the line is m = (by - ay)/(bx - ax) provided bx ≠ ax. From this you can calculate m. Then the general slope-intercept form of the equation is y = mx + c Substitute the coordinates of A or B into this equation to find c. If bx = ax then the line is parallel to the y axis and its equation is x = ax. [There are other methods but they are similar to the above]
A vector has components Ax 12 m and Ay 5 m What is the magnitude of vector A?
Sqrt of 122 + 5 2 = 13
AX plus BY equals AY plus BX?
Ax + by = ay + bxax - ay + by - bx = 0a(x - y) + b(x - y) = 0(a + b)(x - y) = 0-----------------------------------------------------Another contributor continued:Great !When I saw this question, I was about to say "No it doesn't. Not unless A=B."But "Blackfireweb" developed a much more in-depth analysis. Unfortunately, there was asmall error in his algebra, in the third line, where he collects like terms from the second line.Repeating Blackfireweb's work:Ax + By = Ay + BxA(x - y) + B(y - x) = 0A(x - y) - B(x - y) = 0(A - B) (x - y) = 0-- The equation can only be true for all (x, y) if ( A = B ).-- Otherwise, it's only true at a point where ( x = y ).What this really means is: Whatever numbers you pick for 'A' and 'B', if you write an equationsuch as appears in the question and then massage it a bit, you always find that you havethe equation ( Y = X ), and you realize that we have all been making something complicatedout of something simple.Notice that the "question" doesn't even ask any question. It just makes a statement.To which we reply: "OK. That's the equation ( Y = X ). So what ?"
