Answer:
x = - 6
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 = - 9 when x = 3, thus
k = 
= 
= - 3
y = - 3x ← equation of variation
When y = 18, then
18 = - 3x ( divide both sides by - 3 )
x = - 6
Answer:
The required factored form of the given expression is
(x^4 y^6+1)(x^8 y^12-x^4 y^6+1) as the factored form.
Answer: they will have to pay 50 dollars
Step-by-step explanation: you have to multiply 2,500 by 0.02 as it is the same as a percent then you should get 50
Using a calculator can help. You get 0.625, or 5/8.
Answer:
