How do you differentiate y equals x minus a over x?
If you mean: y = x - a/x Then: y = x - ax-1 y' = 1 + ax-2 y' = 1 + a/x2 If you mean: y = (x - a)/x Then: y = 1 - ax-1 y' = ax-2 y' = a/x2
Which 2 numbers have a mean of 10 and a range of 4?
As there are two numbers, the range is the difference between themAs there are 2 numbers the mean is exactly in the middle of them.Thus half the range is less than the mean and half the range is greater than the mean.Thus the two numbers are 10 ± (4/2) = 10 ± 2 = 8 and 12.Algebraically, this can be seen:Let the two numbers be x and y with y > xThen:their range is y - x = 4; andtheir mean is (x + y) / 2 = 10{2} can be rearrange to give x + y = 10 × 2 → y + x = 20adding {3} to {1} yields: (y + y) + (-x + x) = 20 + 4 → 2y = 24 → y = 12subtracting {1} from {3} yields (y - y) + (x - -x) = 20 - 4 → 2x = 16 → x = 8→ the two numbers are 8 and 12.
If x plus y7 and 2x-y2then y?
If you mean: x+y = 7 and x-y = 2 then x = 3 and y = 4
What does find a quotient mean?
The quotient of two numbers, X and Y, is X/Y.
In math x and y equals what?
In math x and y means unknown answer. The mystery numbers are always different like x doesn't mean 3 and y doesn't mean 0.
What does nomerator mean?
Mispelling of 'numerator'. Numerator is the top half of a fraction. If you have x/y, then x is the numerator.
Half the sum of x and y?
(x + y)/2 ------------
What is the answer of y equals 2x?
x equals half y
If y equals one half and x equals negative fourteen what is y?
One half!
What is the algebraic expression for the one half the sum of x and y?
1/2 (x+y)
How do you differentiate y equals x minus a over x?
If you mean: y = x - a/x Then: y = x - ax-1 y' = 1 + ax-2 y' = 1 + a/x2 If you mean: y = (x - a)/x Then: y = 1 - ax-1 y' = ax-2 y' = a/x2
How do you find the sum of xy when x 45 and y1094?
If you mean "What is the answer to x*y when x=45 and y=1094?" then the answer is 49,230. If you mean "What is the answer to x+y when x=45 and y=1094?" then the answer is 1,139.
What does x goes into y mean?
X goes into Y is really Y divided by X

How do you write x equals one half y in general form?
x= y (1/2) or x= y/2 or x= y times 1/2 or x= 1/2y
Evaluate x plus y for x 16 and y 14?
If you mean: x = 16 and y = 14 then x+y = 30
How do the slopes of the two parts of an absolute value function compare?
the graph of y = |x| (absolute value of x) looks like a V with the point of the V at the origin. When x is negative (left half of graph), the line y = -x coincides with |x| so this half has a slope of -1. When x is positive (right half of graph), the line y = x coincides with |x| so this half has a slope of +1.
