How do you rewrite this equation so that y is a function of x 2x plus y equals 7?
y=f(x)= x(2x+y)=7 f(x)=2x^2 +xy -7 = 0 y=2x^2 +xy -7 y-xy -7 + 2x^2 = 0 y(1-x)=2x^2-7 y=(2x^2-7) / (1-x) Excuse the working. Y equals 2 X squared minus 7 all divided by 1-X
Implicit differentiation of xy plus x equals 2?
It equals y+1
Find the coordinate of X if XY equals 1 and the coordinate of Y is 0?
If Y = 0 then there is no value of X such that XY = 1.
X plus XY equals 8 solve for Y?
x+xy=8 xy=-x+8 y=-1+8/x
What is the value of the expression 4x-2y plus xy when x equals -1and y equals 5?
Just plug in the values for x and y. 4(-1) - 2(5) + (-1)(5) = -19
If x equals 0 and y equals 1 what is the value of xy?
"xy" refers to the product of "x" and "y". Just substitute the variables for numbers, and do the multiplication.
What are the factors of xy plus x plus y plus 1?
xy + x + y + 1 = (x + 1)(y + 1).
What is the property for xy equals 1 xy?
That is the commutative property of equality.
If xy equals x or yx equals x what is y?
xy = x ÷x y = 1
How xy plus x plus y plus 1 will solve?
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
What is 1 plus 3z equals?
It equals 1 + 3z and, unless you know the value of z, you are not going to be any the wiser as to its value.
If x equals -8 and xy equals 1 what does y equal?
So far you know that: x=-8 xy=1 so xy means x times y. If you split xy. y=1/x or y=1/-8 1/-8= -0.125 You can find out that this is correct with the formula xy=1 because -0.125 x -8 is 1.
What does 2p plus 1 equals?
That depends what the value of p is.
