i tihnk this is a dumb question but why is -x*x=-y? i tried thinking about it like a arrays on a graph but it was kinda confusing.
Is there another answer?HallsofIvy said:If you mean "why is a negative number times a positive number negative?" then honestrosewater gave a pretty good answer.
Fishy.(what would DIShonestrosewater smell like?)
The expression -x*x = -y is a mathematical equation that represents the relationship between two variables, x and y. The negative sign in front of the x indicates that it is being multiplied by itself, or squared. This means that the value of x is being multiplied by itself and then being multiplied by -1. The result of this operation, -x*x, is equal to -y, which means that the value of y is the negative result of squaring x.
The negative sign in front of the x is important because it indicates that the value of x is being squared and then multiplied by -1. This negative value is then equal to the value of y. Without the negative sign, the equation would simply be x*x = y, which would give a positive value for y instead of a negative one.
The equation -x*x = -y is commonly used in science to represent inverse relationships between variables. In other words, as one variable increases, the other decreases. This relationship can be seen in various scientific phenomena such as the ideal gas law, where pressure and volume have an inverse relationship.
The reason x is squared in this equation is because of the mathematical concept of squaring a number. When a number is squared, it is multiplied by itself. In this equation, x is being multiplied by itself and then multiplied by -1 to get the value of y. This helps to establish the inverse relationship between x and y.
Yes, there are many real-world applications of the equation -x*x = -y. As mentioned before, it can be used to represent inverse relationships in science. It can also be used to calculate areas of squares and rectangles, as well as to solve quadratic equations. In physics, this equation is used to calculate kinetic energy, where x represents the mass of an object and y represents its kinetic energy.
