Im confused on how to use distance formula on this

Mathematics
1 answer:
zheka24 [161]2 years ago
4 0

Answer:

Not sure what you need ----see below

Step-by-step explanation:

Leg 1  of left triangle  = 8 units

Leg 2                          = 6

Hypotenuse               = 10  ( via Pythag theorem....or distance formula)

R triangle  Leg1 = 8 units

                  leg 2 = 6 units

        hypotenuse = 10 units      so the triangles are congruent by SSS

distance from right angle of triangle 1 ( at 0,0)   to

               right angle of triangle 2  ( at 6,-3)  

                     using<u> distance formula </u>

                      from 0,0  to 6, -3

              d^2 = ( 6-0)^2  + (-3 -0)^2

               d^2 = 45

                d = sqrt 45

Over a period of five days, the average time of a commuter train trip from one town to the city was 77 minutes. One trip was 71
OverLord2011 [107]
Average time of a commuter train trip from one town to the city = 77 minutes
Time taken by 1 trip = 71 minutes
Time taken by another trip = 74 minutes
Time taken by 3rd and 4th trip each = 78 minutes
Let us assume the time taken during the 5th trip = x
Then
(71 + 74 + 78 +78 +x)/5 = 77
301 + x = 77 * 5
301 + x = 385
x = 385 - 301
   = 84 minutes
So the length of the fifth trip was 84 minutes. I hope the procedure is clear enough for you to understand.

Given 2x - 9y - 12 = 0, express 5x - 4y + 7 = 0 in terms of x only
olga2289 [7]

Answer:

4 \frac{1}{9}x + 12\frac{1}{3} = 0

Step-by-step explanation:

Based on 2x - 9y - 12 = 0

-9y = 12 - 2x

9y = -12 + 2x

y = -1\frac{1}{3} + \frac{2}{9} x

Therefore...

5x - 4y + 7 = 0

5x - 4(-1\frac{1}{3} + \frac{2}{9} x) + 7 = 0

5x + 5\frac{1}{3}  - \frac{8}{9} x + 7 = 0

4 \frac{1}{9}x + 12\frac{1}{3} = 0
