A line passes through the two given points. Is it vertical, horizontal, or neither?
Leviafan [203]

<u>Answer:</u>

A line passes through the two given points (5,2), (5,-2). The line is vertical line

<u>Solution:</u>

Given, two points are (5, 2) and (5, -2)

We have to find that a line that passes through the given two points is vertical or horizontal or neither.

First let us find the slope of the line that passes through given two points.

So, slope of line m =\frac{y_{2}-y_{1}}{x_{2}-x_{2}} \text { where, }\left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right) \text { are two points on line. }

So slope of our line =\frac{-2-2}{5-5}=\frac{-4}{0} = undefined

Here slope of our line is undefined which means it is parallel to the y – axis.

Hence, line passing through given points is vertical line

In rectangle DATE, the diagonals DT and AE intersect as S. If LaTeX: AE=40 A E = 40 and LaTeX: ST=x+5 S T = x + 5 , find the val
svetoff [14.1K]
For this case we have the following diagonals:
 AE = 40
 ST = x + 5
 The intersection of the diagonals occurs when:
 AE = ST
 Therefore, matching we have:
 40 = x + 5
 Clearing x we have:
 x = 40-5
 x = 35
 Answer:
 The value of x is:
 x = 35

Sophie [7]
Using the compound interest formula,

A = P(1+r)^n

A = 17000

r = 4% quarterly

n = 8yrs = 32 quarters of a year

P = ?

17000 = P(1+4%)^32

P = $[17000/((1+4%)^32)]
