Consider the equation pv=ktn , where k is a constant. select all of the correct answers that describe the variation between variables. (there can be more than one answer pls ) t varies directly with v p varies directly with t n varies inversely with v n varies inversely with t p varies inversely with n v varies inversely with p

p varies directly with T and T varies directly with V. Option A and B are correct

If y is directly proportional to x, this is expressed as y = kx where:

k is the variation constant

It shows that as the value of y is increasing, the value of y is also increasing and vice versa.

Given the function pV=kTN, we can see that "k" here is the variation constant, this shows that p and V is directly proportional to T and N.

Based on the given option, we can conclude that;

p varies directly with T and T varies directly with V

Step-by-step explanation:

Rule: If the variables are on the same side of the equal sign, they vary INVERSELY.

If the variables are on the opposite side of the equal Sign, they very DIRECTLY.

a) T and V

b) p and T

c) N and V

d)  N and T

e)  p and N

f)  V and P

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

x=6 and x=3
