Answer:
Just subtract 47 from 68 and the answer is D.
Answer:
no
Step-by-step explanation:
Move the -18 across so that x^2+11x+18<0
then solve as if equal to 0
(x+9)(x+2)<0
x=-9 and x=-2 put these on a graph and it is less than 0 when within the graph hence x>-9 and x<-2
Answer:
x = 23/9
y = 1/9
Step-by-step explanation:
2x - y + y - 5 = 5 + y - 5
2x - 5 = y
3x + 3(2x - 5) = 8
3x + 6x - 15 = 8
9x/9 = 23/9
x = 23/9
2x - 5 = y
2(23/9) - 5 = y
46/9 - 5 = y
1/9 = y
