35%
---- Than cross multiply with ---- = 24500
100% 100 --------
100
Which ends up to be 245.
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

Tina can finish in 5 hours
Bill takes two hours longer than Tina.
5+2=7
Bill takes 7 hours to cut the lawn.
7+5=12
It takes both of them working together 12 hours. Hope this helped!
Answer:
-9x + 10
Step-by-step explanation:
Answer:
The minimum point is (4,-3)
Step-by-step explanation:
we know that
If the new equation is
y=f(x-5)
then
The Rule of the translation is
(x,y) -----> (x+5,y)
That means ----> The translation is 5 units at right
so
(−1,−3) ----> (-1+5,-3)
(−1,−3) ----> (4,-3)
