Answer:
C
Step-by-step explanation:
1*18 2*9 3*6
The answer is 1.869 or 1.87
Answer:
2x^2+6x-5-(9/(x+3))
Step-by-step explanation:
(2x^3+ 12x²+13x-24)/
(x+3) =
Kx-3y=k
y=4x+1 ( we will put it in 1st equation )
kx - 3 (4x+1)=k
kx - 12 x - 3 =k
kx - 12 x = k+3
x(k-12) = k+3
x=
![\frac{k+3}{k-12}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bk%2B3%7D%7Bk-12%7D%20)
Also y=
![\frac{5k}{k-12}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5k%7D%7Bk-12%7D%20)
We can not divide with zero.
k-12=0
k=12For k= 12 equations have no solutions.
Answer:
-4(5x - 9) + 6(2x + 5)
multiplication of:
(-).(-) = +
(-).(+) = -
(+).(-) = -
(+).(+) = +
-4(5x) -4(- 9) + 6(2x + 5)
(-)(+)4(5x) (-)(-)4(9) (+)(+) 6(2x) (+)(+)6( 5)
-20x + 36 + 12x + 30
-20x + 12x + 36 + 30
-8x + 66
