Reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.
Consider a plane. Consider a design or shape on that plane. Now consider an axis.
If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.
Instead of that mirror intuition, we can also think that we sort of rotated that image about that considered axis, and after half rotation, the figure is again onto its plane. If that rotated figure looks alike to the initial figure, then that figure has rotational symmetry.
Thus, reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.

There are three methods used to solve systems of equations: graphing, substitution, and elimination
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

The three methods used to solve systems of equations: graphing, substitution, and elimination
Solving an equation by Graphing :
Simply graph the provided equations and discover the point(s) where they all cross to solve a system. The coordinate of this point will provide you with the values of the variables you are attempting to solve for. This works well when the equations are already in slope-intercept form.
Solving an equation by Substitution:
Substitution is best used when one of the equations is in terms of one of the variables. Once an expression for the variable has been found, substitute or plug it into the other equation where the original variable was to solve for the next variable's integer value. The final step is to substitute the discovered number value for its corresponding variable in the original equation.
Solving an equation by Elimination:
Elimination is the process of combining the equations to obtain an equation with only one variable. This is only possible if the coefficients of one variable in both equations are diametrically opposed and will cancel each other out when put together.
The next step would be to use the equation we devised to determine the variable's value, and then plug that value back into the original equation to determine the remaining variable.
Hence , There are three methods used to solve systems of equations: graphing, substitution, and elimination
