A triangle has vertices at A(-7, 6), B(4,9), C(-2, -3). What are the coordinates of each vertex if the triangle is translated 4 units right and 6 units down?

Add 4 units to each of the x coordinates

subtract 6 from each of the y coordinates

example    A (-7,6)   becomes  A' ( -3 , 0)     etc  

1 wall/ (1 wall/ j+ 1 wall/ k)   = 6     where  j  and  k are the times for each  Jeff and Kirk

1 wall/ (j)   =   1 wall/(k  -2)    sub this into the first equation above

1 /  (( 1/(k  -2) + 1/k  )  = 6

1  /   k-2 +k  / (k^2 - 2k)

(k^2-2k) / (2k-2)   = 6

k^2 -2k = 12k - 12

k^2 -14k + 12 = 0      k =  13.0828   or   .91724  hrs (throw out)

k=13.0828 hrs   then   j  = 11.0828 hrs

check     1 /   (1/11.0828  + 1/13.0828)      = 6 ?

                        6                                         = 6        Check !

Kirk by himself =    13.0828 hrs   =  ~~13 hrs 5 mins

.065 for WHAT ?

I got one of the classes earned $ 3.93 more than the other......you'll have to follow the instructions above to find out which earned the most....

i dunno

I got 0.065

I will assume that 2m  means one number 2m   and NOT m + m   and 3m does not mean three m's

x = (m+9)/2        y = (2m+15)/2        z = (3m+18)/2

To find their average, add them together and divide by 3

[    (m+9)/2   +  (2m+15)/2  + (3m+18)/2  ]   / 3

(6m + 42)/2    /  3

3m+21   /  3

m+7

Area of the circle before reduction

pi d = circumference   pi d = 48 pi    so   d   = 48   and radius = 24

pi r^2  =  pi 24^2 =  576 pi

reducit it by 47 pi = 529 pi

now find reduced radius    pi r^2  = 529 pi

                                              r^2 = 529             r = 23

Origianl radius was 24    reduce it by ONE to get to new radius of  23 

Q asks for a system of equations,,,,   soooo here they are

p + j  = 79                                 or     79 - p  = j

1.65 p   + 1.36 j   = 118.17            substitute in the red equation for j

165 p  + 1.36 (79 - p) = 118.17      solve for p   then  79-p = j    

      then you can calculate how much each classs earned       1.65 p   vs.  1.36 j

Pretty sure it is  8 and 8      product = 64

x (16-x)

-x^2 + 16x      upside down parabola

Max is at   -b/2a    =   16/2  = 8

Sub in x = 8     64    yep.....

150 ft /  15 ft / 1 u  = 10 u

120 ft / 15ft / 1 u    =   8 u

10 x 8 u

From 1 to 9 =9
From 10 to 99 =2 x 90 =180
from 100 to 999 =3 x 900 =2,700
from 1000 to 9999 =9,000 x 4 =36,000
from 10,000 to 99,999 =90,000 x 5 =450,000
from 100,000 to 149,999 =50,000 x 6 =300,000
1,000,000 - 788,889 =211,111 / 6 =35,185
From 150,000 to 185, 184 =35,185 x 6 =211,110
So: 9 + 180 + 2,700 + 36,000 + 450,000 + 300,000 + 211,110 =999,999 up to and including 185,184.
Therefore, the 1,000,000th digit is 1 from the beginning of 185,185.

I think if you opened one door you could see the backside of all of the others to determine if this was true or not.   

'x' = number of postcards

sends off 5      now has    x-5   remaining

sends off 1/2         now has    1/2 (x-5)   remaining

thens sends one to sis       1/2 (x-5) -1   remaining   and this equal   4

1/2 (x-5) -1   = 4          solve for 'x' the number of postcards he purchased....     

You are correct.....I used 2004 instead of 2014      yikes !    Thanx...I fixed it !

1 is to 100 000   as   'x' is to 44 700

1/100 000  =  x / 44700

44 700 / 100 000 = x   ft       Then convert your answer to inches by multiplying by  12 in/ft       

     WHERE is this mountain???? 

EP: You made a little typo.

262.50 / 220.9 =1.1883205^(1 / 14) =1.012400 - 1 x 100 = 1.24 % per year.

See this answer and you SHOULD be able to figure thisone out:

https://web2.0calc.com/questions/geometry_72073

The model is the smaller number (it's a model after all)

Make sure that your dimensions are all in cm     model 6cm    car 300cm

car : model

300 : 6      which simplifies    to   50: 1

It increased 14 years    from  2000 - 01     01-02     02-03     and   03-04    etc ...

220.9 (r)^n  = 262.5

r^14  = 262.5/220.9

r^14 = 1.188320507          solve for    r 

Exterior angles of a polygon sum up to 360 degrees

360/20 = n   

Use the fact that (height of flagpole)/(length of shadow) = tan(angle of elevation).
