Answer:No solution. If you graph it they are parallel lines and will never intersect.

Step-by-step explanation: I recommend getting Photomath. It shows how to do it step by step and gives you an answer.

In a triangle ABC, AD is drawn perpendicular to BC. <br> Prove that AB2 - BD2 = AC2 - CD2.
Finger [1]

Answer:

Given: In triangle ABC , AD is drawn perpendicular to BC.

Since AD is drawn perpendicular to BC, it creates two right triangles: ADB and ADC.

Prove that: AB^2-BD^2 = AC^2-CD^2

Pythagoras triangle for right angle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.

In a right angle triangle ADB;

AD^2+BD^2 = AB^2                 [By Pythagoras theorem]

or

AD^2= AB^2-BD^2                      .......[1]

Now, in right angle triangle ADC;

AD^2+CD^2 = AC^2                [By Pythagoras theorem]

or we can write this as;

AD^2= AC^2-CD^2                    ......[2]

Substituting the equation [1] in [2] we get;

AB^2-BD^2 =AC^2-CD^2            hence proved!

Through: (1,-5), perpendicular to y=18x+26
stiks02 [169]

Answer:

Step-by-step explanation:

If you're asking for the equation of a line that goes through (1,-5) and is perpendicular to y=18x+26 here's what you do.

1. find the slope of the new line by taking the negative reciprocal of the slope of the first line (-\frac{1}{18})

2. plug in the point (1,-5) and the new slope into the point slope form equation

y_{2} -y_{1}=m(x_{2}-x_{1})

3.Now that you have y-(-5)= -1/18(x-1) simplify

3.a y-(-5)= -1/18x + 1/18

3.b y=-1/18x - 89/18

4. final equation you get is y = -1/18 - 89/18
