L1 : y = 2x , (2) find the equation of the line L2 perpendicular to L1 passing through the point P = (1, 2).
just olya [345]

Answer:

<h2>2y+x = 5</h2>

Step-by-step explanation:

Given the line L1 as y = 2x perpendicular to an unknown line L2 passing through the point P = (1, 2), we are to find the equation of line L2. to find the equation of the line L2, we will use the point-slope equation of a line expressed as y-y₀ = m(x-x₀)

m is the slope of the unknown line

(x₀, y₀) is the given point.

First is to get the slope of the known line:

comparing the line L1: y = 2x with the standard equation of the line y = mx+c, it can be seen that m = 2

Then we will calculate the slope of the required line.

Since L1 is perpendicular to L2, the product of their slope will be -1 i.e

mm₁ = -1 where m₁ is the slope of the required line L2.

Given m =2

m₁ = -1/m

m₁ = -1/2

Finally we will calculate the equation of line L2 by substituting the slope of line L2 and the point in the point slope equation above;

y-y₀ = m(x-x₀)

Given (x₀, y₀) = (1,2) and m₁ = -1/2

y-2 = -1/2(x-1)

open the parenthesis

y-2 = -x/2+1/2

multiply through by 2:

2y-4 = -x+1

2y+x = 1+4

2y+x = 5

<em>Hence the equation of the line L2 is 2y+x = 5</em>

The height of Tower A is 720 feet more than Tower B. The two towers have a combined height of 1,982 feet. What are the heights o
Kobotan [32]
Okay so. 

We have two basic equations 

Tower A+ B+720    A is 720ft taller than B. 
Tower A+B= 1982     Combined height is 1982ft

Replace A with B+720 in 2nd equation and solve for B 

B+720+B=1982   Combine like terms 
2B+720=1982     Subtract 720 from both sides
2B=1262              Divide both sides by 2
B=1262/2 
B= 631ft 

We know that A=B+720 so you simply need to do that addition to have the height of both towers.
