Andrea says that a system of two linear equations must have at least one solution as long as the lines have different y-intercepts. For example, the equations y = 2x + 4 and y = 4x - 6 have different y-intercepts and have a solution at
(5, 14).
Select the pair of linear equations that can be used to disprove Andrea's claim.

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

so, converting firstly the mixed fractions to improper fractions and then "adding".
