Joseph has started completing the square on the equation 3x2 - 7x + 12 = 0. he has worked to the point where he has the expression x2 - x = -4. use complete sentences describe joseph’s steps up to this point and whether or not his work is accurate.

Joseph has started completing the square on the equation where

given equation is

move constant term to other side.

divide both sides by coefficient of x^2 that is by 3

This is the same step upto which Joseph has worked. But he got different equation

Hence his work is not accurate.

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
