\(y = x + 3\) is a linear equation and \(y = x^2 + 3x\) is a quadratic equation. If the product of two numbers is zero, then one or both numbers must also be equal to zero. To solve, put each ...

you need to find the value of the unknown variable by performing the same operations on both sides. To solve an equation, more than one step may be needed to find the unknown variable. Remember to ...

Some key advantages of linear regression are that it can be used to predict values of the outcome variable and incorporate more than one explanatory variable. The linear regression equation is perhaps ...
