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 =
=
= 
Maybe if i add 10 + 30 is = 40 this is my answer
Answer:
k=-2x+9
Step-by-step explanation:
-4x+6=k*2x-3
+3 +3
-4x+9=k*2x
/2x /2x
-2x+9=k
The equation for the table is f(x)=3x+1 so I don’t know for a but for b it would be f(x) because 1 is greater than 5.
Hi hope I helped, ok so first 6×7=42 and its less than 53 so ur answer is 42
