Answer:

  B) Use the slope formula to prove the slopes of the diagonals are opposite reciprocals.

Step-by-step explanation:

A distance formula is used to find the length of a line segment. Knowing diagonal lengths cannot tell you they are perpendicular, eliminating choices C and D.

Diagonals of a quadrilateral are never parallel, so choice A makes no sense.

The slopes of the diagonals of a quadrilateral will be opposite reciprocals if the diagonals are perpendicular. The slope formula can be used to show that is the case. Choice B is the appropriate answer.

The reflection of a point P across a line m is the
masya89 [10]

Answers:  perpendicular bisector;  image

  • The reflection of a point P across a line m is the point P' if line m is the <u>   perpendicular bisector    </u> of segment PP'
  • Point P' is called the <u>     image    </u> of point P.

=============================================================

Explanation:

If we were to reflect point P over line m to land on P', then we've gone from pre-image to image.

Let's say that Q is the point on segment PP' and it's also on line m. We consider Q the midpoint of segment PP' which means PQ and P'Q are the same length. This indicates P and P' are the same distance away from the mirror line, and that point Q bisects segment PP'. Also, line m is perpendicular to segment PP'. So that's where the "perpendicular bisector" comes from.

A lotion is made from an oil blend costing $1.50 per ounce and glycerin costing $1.00 per ounce. Four ounces of lotion costs $5.
yanalaym [24]
X-ounces of an oil blend,
y - ounces of glycerin
x + y = 4    ⇒   y = 4 - x
1.5 x + y = 5.50
1.5 x + 4 - x = 5.50
0.5 x = 5.50 - 4
0.5 x = 1.50
x = 3
y = 4 - 3 = 1
There are 3 ounces of an oil blend and 1 ounce of glycerin.
