Which of the following is NOT true of a perpendicular bisector?
kodGreya [7K]

To construct a perpendicular bisector, we have to draw two arcs using each of the endpoints as centers

<h3>What is a perpendicular bisector?</h3>

A perpendicular bisector is said to be a line that intersects the segment of another line perpendicularly and also divides it into two equal parts.

The properties of a perpendicular bisector include:

  • It divides a line segment into two equal parts
  • It makes right angles with the line segment.
  • Points in the perpendicular bisector are equal from the line of the segment.

Hence, all the mentioned properties are correct except that to construct it, we have to draw two arcs using each of the endpoints as centers.

Which of the following represents the total cost of the shoes by applying the $15 coupon first and the 20% member discount secon
murzikaleks [220]

Considering the definition of an equation and the way to solve it, the total cost of the shoes is 0.20×(x-15).

<h3>Definition of equation</h3>

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.

The members of an equation are each of the expressions that appear on both sides of the equal sign while the terms of an equation are the addends that form the members of an equation.

<h3>Total cost in this case</h3>

Being "x" the price of the shoes, and knowing that:

  • you apply a discount of $15 first → x -15
  • you apply a discount of 20% through a second discount (
  • (applied on the first discount already made) → 20%×(x-15) → 0.20×(x-15)

the equation in this case is:

<u><em>Total cost= 0.20×(x-15)</em></u>

Finally, the total cost of the shoes is 0.20×(x-15).
