Consider the function represented by the equation 1/2j+1/4k=3. which shows the equation written in function notation with j as the independent variable?

f(j)=-2j+12
f(j)=-1/2j+6
f(k)=-2k+12
f(k)=-1/2k+6

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
