D = M/V
D= 21/7
D = 3 g/cm3
To have infinite solutions, they have to be th esame line
match waht we do know
bx-6y=18
the coefient of y is -6
other one is
2x-3y=9
-3 times 2=-6
times 2nd equation by 2
4x-6y=18
bx-6y=18
b=4
Answer:
B.
Step-by-step explanation:
It is just common sense. The top numbers have to be smaller than the top numbers
Answer:
here's how you can factor it:)
Step-by-step explanation:
=6x+9
=(x+3)(x+3)
x= -3
Answer:
True
