The variable z is inversely proportional to x. when x is 6, z has the value of 2. what is the value of z when x=13
round to at least the thousandths place if needed

Step-by-step explanation:

we know that

A relationship between two variables, x, and z, represent an inverse variation if it can be expressed in the form or

step 1

Find the value of k

For x=6, z=2

substitute

therefore

The equation of the inverse variation is equal to

step 2

What is the value of z when x=13

substitute the value of x in the equation and solve for z

show us the graphs dude

step-by-step explanation:

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
