Answer:
1632
Step-by-step explanation:
(78 x 3) = 234
234 x 7 = 1638
1638 - 6 = 1632
From that order, top to bottom.
Answer:
Step-by-step explanation:
y=-3x²-4x+7...(*)
3x+2y=18...(**)
use (*) put the value of y in (**) :
3x +2(-3x²-4x+7)=18
3x-6x²-8x +14 -18 = 0
-6x²-5x- 4 = 0
6x²+5x+4 = 0
delta = b² - 4ac a = 6 b=5 c =4
delta = 5² - 4(6)(4)= 25 -96= -71 negatif
so no reals solution
