If you mean: x2+2x+1 = 0 then it is a quadratiic equations whose solutions are equal because x = -1 and x = -1
Area of circle is pi x radius squared Circumference is p x diameter
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.

No. Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
Without any equality signs the given expressions can't be considered to be equations.
Provide a system of equations in slope-intercept form that has one solution. Using complete sentences, explain why this system has one solution.

A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.
To solve a system means to find the x- and y-values for which both of the equations are true. Systems of linear equations can be solved using a variety of methods. One method is to graph the equations as two lines and examine them. If the lines intersect at exactly one point, there is one solution to the system, and the system is called consistent. If the two lines are on top of one another, there are an infinite number of solutions, because each point on the line is considered a solution (this system is called dependent). If the two lines are parallel, there is no solution (this system is called inconsistent). To solve a system means to find the x- and y-values for which both of the equations are true.

For the dissociation of substances in aqueous solution, you can write equations using the general form: AB A B- This represents the dissociation of a compound AB into its ions A and B- in water.

Technically, equations are never perpendicular to one another. However, the equations of lines can result in their lines being perpendicular. Using y=mx+b, to have a perpendicular line, you have the negative reciprocal of m.
Which of the following is a disadvantage to using equations?
In math, the purpose of Cramer's rule is to be able to find the solution of a system of linear equations by using determinants and matrices. Cramer's rule makes it easy to find a system of equations that have many unknown variables.
