marin [14]

Answer:

Step-by-step explanation:

-7x + 12 + (-8x + 48) = 180

-15x + 60 = 180

-15x = 120

x = -8

m<BDC= -7(-8)+ 12 = 56 + 12 = 68

m<CBA = -8(-8)+48 = 64+48 = 112

What is the hyperbola 25x^2-100y-9y^2-90x-350=0 in standard form?
sergij07 [2.7K]
WE need to complete the square on the x and y terms:-

25x^2 - 100x - 9y^2 - 90y = 350
25(x^2 - 4x +    ) - 9(y^2 + 10x       )  =   350 + 25(  )  - 9(  )
25(x^2 - 4x  + 4 ) - 9(y^2 + 10x  + 25)  = 350  + 25(4)  - 9(25)
25(x - 2)^2 - 9(y + 5)^2 = 

25(x - 2)^2   -  9(y + 5)^2          =  225
----------------    --------------            --------
    225                 225                    225

  ( x  - 2)^2         (y + 5)^2  
  -------------   -   --------------  =    1         Answer
        9                    25

Carly lives in Scottsdale, AZ and plans to go visit downtown Glendale, AZ. The map with a scale of 2 cm for every 4 km shows the
AleksandrR [38]
Comparing map distance to real distance we get 2cm/4km. That means 1cm = 2km.

So the map distance is half the real distance (well, technically not as one is in cm and the other in km but it’s enough to think this way) and a real distance of 10km must mean a map distance of half that (again ignoring the units) so we get 5cm.
