What is the inverse of y equals 2x plus 3?
I presume you mean given y find x: Make x the subject: y = 2x + 3 => 2x + 3 = y => 2x = y - 3 => x = (y - 3)/2 which can also be expressed as: x = 0.5 y - 1.5
What is an inverese in algebra?
An inverse is another word for opposite. The inverse for adding is subtraction, multiplication is division, etc. If you are solving an equation, and have to get a variable alone, you must eliminate any other numbers with the variable, which means undoing the operation (x, +, -, /); so you perform the inverse. Example: x + 3 = 9. Subtract 3 on both sides to get x alone, because subtraction is the inverse of addition: x = 6. Example: 2x + 3 = 9. You must do the inverse of addition and subtraction before the inverse of multiplication and division. In this case, after subtracting 3 you have: 2x = 6. x is being multiplied by 2, so the inverse is division, and your answer is x = 3.
What is inverse of a function?
Simply stated, the inverse of a function is a function where the variables are reversed. If you have a function f(x) = y, the inverse is denoted as f-1(y) = x. Examples: y=x+3 Inverse is x=y+3, or y=x-3 y=2x+5 Inverse is x=2y+5, or y=(x-5)/2
How do you use inverse opperationto solve an equation or an inequality?
You need to isolate the variable you want to solve for, on one side of the equation. This involves getting rid of everything else. Note that what you do on one side of the equation, you also have to do on the other side. "Getting rid" of everything else basically means doing the inverse of the operation shown. Example: 2x + 3 = 21 You might start by getting rid of the 3. For this, you subtract 3 on both sides. Subtracting 3 is the inverse of the operation shown in the equation, adding 3. 2x + 3 - 3 = 21 - 3 2x = 18 Next, you get rid of the 2. Once again, since in the equation there is a multiplication by 2, you divide by 2 - the inverse operation. In this case, you divide by 2 on each side: 2x/2 = 18/2 (2/2)x = 18/2 x = 9
What is the inverse of fx equals 2x?
g(x) = x/2
What is the multiplicitive inverse of 3 plus 2x?
The multiplicative inverse of 3+2x is 1/(3+2x).
What is additive inverse of -2x?
The additive inverse of a number is the value that, when added to the original number, results in zero. In this case, the additive inverse of -2x would be 2x, since (-2x) + 2x = 0. This concept is based on the properties of addition and the definition of additive inverses in mathematics.
What is the inverse of -x5 - 2x plus 2?
The additive inverse is x5 + 2x - 2.
What is the inverse of the equation y equals 2x plus 3?
x=(y-3)/2
Can you tell the difference between the arigonal equation and the inverse?
I would say that functions have inverses, rather than equations.One simple way to find the inverse of a function is to switch the x and y:The inverse of y = (3x+5)/2 is . . . x = (3y+5)/2.You can take this inverse and solve it for y: (2)x=(2)(3y+5)/2 2x=3y+5 3y+5=2x 3y=2x-5 y=(2x-5)/3.Notice that in the original you multiply by 3, add 5, and divide by 2. On the inverse, you multiply by 2, subtract 5, and divide by 3. You do the inverse operations in the reverse order.

What is the converse of if x equals 3 then 2x equals 6?
I believe the converse is: if 2x equals 6 then x equals 3 inverse: if x doesn't equal 3 then 2x doesn't equal 6 contrapositive: if 2x doesn't equal 6 then x doesn't equal 3
