2 answers:

6 0

After a thorough research, there exists the same question that have choices.

Point, line
Line, plane
Coplanar, line
Point, coplanar 

The correct answer is "Coplanar, Line." The pair of undefined terms that is used to define the term parallel line is "Coplanar, Line" because parallel lines are coplanar in itself that do not intersect.

Answer: A point and a line.

Step-by-step explanation:

There are three undefined terms in geometry which is used to define other terms:

a) Point b) line c) Plane

The definition of parallel lines says that "The two lines are said to be parallel lines if they do not intersect each other at any point. "

Thus, to define parallel lines we have used only two undefined terms i.e. lines and a point .

Hence, the pair of undefined terms is used to define the term parallel lines : Point and Line

You have invested $2000 at 3.75% annual interest. How much money do you have after 20 years?

lbvjy [14]

Answer:

$3500

Step-by-step explanation:

Let's use PRT/100 to see what will be the total amount.

Total amount = Interest + Principle

Solution:

PRT/100 = Interest
=> 2000 x 3.75 x 20 years/100
=> 20 x 3.75 x 20 = Interest
=> 2 x 2 x 375 = Interest
=> 4 x 375 = Interest
=> 1500 = Interest
=> Total amount = 1500 + 2000
=> Total amount = $3500

Hence, after 20 years, the amount earned is $3500.

What is the equation of the line that is perpendicular to y = one-fifth x + 4 and that passes through (5,–4)?

Brilliant_brown [7]

Answer:

y = -5x + 21

Step-by-step explanation:

perpendicular lines have slopes that are negative reciprocals.

The given line has a slope of 1/5, so the perpendicular line will have a slope of -5.

y = -5x + B

-4 = -5(5) + B

B = -4 + 25 = 21

y = -5x + 21

Triangle FGH is similar to triangle DEF. solve for p

malfutka [58]

Answer:

We get value p=16

Step-by-step explanation:

When triangles are similar, the ratio of corresponding sides is equal.

In the given triangles we have to find value of p

We have the ratio: (Can use ratio of any two sides)

$\frac{HF}{PD} =\frac{GF}{ED}$

Now, putting values and finding p

$\frac{12}{p}=\frac{24}{32}\\Cross\:Multiply\\12\times 32 = 24 p\\p=\frac{384}{24}\\p= 16$

So, we get value p=16
