Question 1. What is the solution to the following system? y = -6x
y = 48

1. infinite solutions
2. (-6, -8)
3. (-6, 48)
4. (-8, 48)

Question 2. What is the solution to the following system?
2x + 7y = 3
y= -1

1. (5/7, -1)
2. (-1, 5)
3. (5, -1)
4. (5, -5)

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

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
