Answer:
18
Step-by-step explanation:
27/150*100/1
divide by 3
9/50*100
100/50=2
9*2=18
Answer:
y = 
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y =
when x =
, thus
=
= 2k ( divide both sides by 2 )
k = 
y =
← equation of variation
When x =
, then
y =
=
= 
The axis of symmetry is 2 and the vertex is (2, 4).
Answer:
6(2a+4)-4(3a-4)= (12a+24) +(-12a+16) = 40
