What is the inverse of y equals 4x-2?
6
What is the inverse operation multiplying by 25?
The inverse of multiplication is division. y = 25x Substitute y for x and x for y to determine the inverse: x = 25y y = x/25
Suppose that y varies with x Write an equation for the inverse variation y 4 when x 7?
If y varies with x, then there cannot be an inverse variation between x and y!
If y varies inversely with x and y equals 5 when x equals 7what is the value of y when x equals 4?
If we assume a constant inverse relationship then we can start with the equation y = c/x where c is the constant of proportionality. Plugging in the known values of x = 7 and y = 5 we determine that c = 35. We now have the equation of y = 35/x. Plugging in 4 for x we see that y = 35/4 = 8.75.
What is the difference between multiplicative inverse and additive inverse?
The multiplicative inverse of a non-zero element, x, in a set, is an element, y, from the set such that x*y = y*x equals the multiplicative identity. The latter is usually denoted by 1 or I and the inverse of x is usually denoted by x-1 or 1/x. y need not be different from x. For example, the multiplicative inverse of 1 is 1, that of -1 is -1.The additive inverse of an element, p, in a set, is an element, q, from the set such that p+q = q+p equals the additive identity. The latter is usually denoted by 0 and the additive inverse of p is denoted by -p.
What is the inverse to the statement x equals y?
x=y is the identity. It is its own inverse. So the inverse is y=x.
Is x plus y equals 8 a inverse varition?
x+y=8 y=-x+8 is not an inverse variation. However, y=8/x is an inverse variation or y varies inversely as x.
What is the inverse of the equation y equals 4x?
To find the inverse, replace y with x, and x with y. So, the inverse of the equation is: x = 4yWhich is equal to:y = x/4
What is the inverse of y equals 2 to the x power?
if y = 2x then x = log2 y
In inverse proportion x equals 2 and y equals 36 but what will y be when x equals 4?
Inverse proportion implies xy = c where c is the constant of [inverse] proportionality. x = 2 and y = 36 implies xy = 72 = c So the relationship is xy = 72 Then, if x = 4, y = 72/x = 72/4 = 18
Is x pluse y equals 7 direct or inverse variation?
Inverse: as x increases so y diminishes and vice-versa.
Why is the graph of an inverse of a function flipped over the line y equals x instead of another line?
Because the inverse of a function is what happens when you replace x with y and y with x.
What is the transformation that maps y equals sinx onto y equals the inverse of sinx?
f(x) = 1/x except where x = 0.
What is the inverse of y equals 5x-12?
17
What is the inverse function of y equals 2x minus 4?
To find the inverse of a function, you replace x with y and y with x. Here, y=2x-4 would become x=2y-4. Now, we solve for y. 2y=x+4. y=(x/2)+4, and that is the inverse equation.
What is the inverse of the function y equals log 5 x?
log5x
What is the inverse of y equals x squared plus 2?
y-1=(x-2)^1/2
