Answer: The answer is (B) They show direct variation because y=x+2 and 10-5=12-7.

Step-by-step explanation: We are given two points (5 7) and (10, 12) and we are to select the correct statement about the two given points.

Since we have

7 = 5 + 2 and 12 = 10 + 2, so we can directly say that the equation of the line passing through the two points will be

y = x + 2.

Since we can directly find the relation between x and y, so we can say that they show direct variation because y=x+2 and 10-5=12-7.

Thus, the correct option is (B).

Given: CD is a perpendicular bisector of AB . Prove: Any point on CD is equidistant from the endpoints of AB . Match each statem

Sunny_sXe [5.5K]

Answer:

The two triangles are congruent, so any point on CD will be equidistant from endpoints of AB.

Step-by-step explanation:

Let the consider the figure as per the attached image:

AB be a line whose perpendicular bisector line is CD.

CD divides the line AB in two equal line segments making an angle of $90^\circ$ on both the sides as shown in the attached figure.

Let a point on CD be E.

Here, two triangles are formed:

$\triangle AED\ and \ \triangle BED.$

Side ED is common between the two triangles.

Also, Side ED is perpendicular bisector:

$\angle EDA = \angle EDB =90^\circ$

And Sides AD = DB

According to SAS congruence (i.e. Two sides are equal and angle between them is equal):

$\triangle ADE \cong \triangle BDE$

And as per the properties of congruent triangles, all the sides are equal.

$\Rightarrow EA = EB$

EA and EB is the distance of point E on line CD from the endpoints of line AB.

Hence proved that Any point on CD is equidistant from the endpoints of AB .

If x and y are positive numbers xy = 96 what is the value of x

Sunny_sXe [5.5K]

The value of x is 96/y where y is not equal to zero.

Given the expression that relates x and y as xy = 96

We are told that x and y are positive numbers. To get the value of x, we will divide both sides by y as shown:

$xy = 96\\\frac{xy}{y} =\frac{96}{y} \\x = \frac{96}{y} \\$

From the result, we can conclude that the value of x is 96/y where y is not equal to zero.
