About this tutor › y is a variable just like x is a variable. So what’s a variable, right? It’s a symbol we use when we don’t know how many we have of something or when the number of them can change. y + 5 means we add 5 to whatever we decide y stands for.
What is a solve Y?
Solving for y means that we have to get y by itself. Therefore, we have to move everything else to the other side.
What is the answer to 7y?
7y = 1+8y. Move the 8y to the left hand side by subtracting 8y from both sides, like this: 7y – 8y = -y. The answer is -y. A monomial is an expression in algebra that contains one term, like 3xy….What is the degree of 4?
| Degree | Name | Example |
|---|---|---|
| 4 | Quartic | 6×4−x3+x−2 |
| 5 | Quintic | x5−3×3+x2+8 |
What does 8y mean algebra?
1 Expert Answer When a number and a representation are written this way, i.e. “8y”, you must mulitply them. If there is more information, you can figure for “y”. If there is no other information, “y” is simplied and the end result is “8y”.
What is Y value?
Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 – y2] / [x1 – x2]. If you know x, you can solve for y to find the y value for the slope of the line.
What is an example of algebra?
Algebra helps in the representation of problems or situations as mathematical expressions. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression. One simple example of an expression in algebra is 2x + 4 = 8.
What does 7y mean in algebra?
Y is a variable which serves as a placeholder for some number. To find y, or solve the equation, we want to get the variable by itself on one side of the equation. Just as a reminder, 7y means 7 times y.
What is algebra formula?
Algebraic equation, statement of the equality of two expressions formulated by applying to a set of variables the algebraic operations, namely, addition, subtraction, multiplication, division, raising to a power, and extraction of a root. Examples are x3 + 1 and (y4x2 + 2xy – y)/(x – 1) = 12.
