Answer: B
Step-by-step explanation:
Factor
b(b+12)=0
set to zero
b=0
b+12=0
b=-12
b=0 or -12
written as this way
b=-12,0
Yes you are correct very nice job!
The answer would be 400,000.
Answer:
y = 36x
Step-by-step explanation:
Given that y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 18 when x =
, thus
k =
=
= 36
y = 36x ← equation of variation
