I need help with systems of equations

1st page are parallel lines slope is zero since they are horizontal lines. 2 nd page X= -2. Y= -3

Step-by-step explanation:

Substitute -2x+1 in the y

Y=-4x-3

-2x+1= -4x-3

+4x. = 4x

2x+1= -3

-1= -1

2x= -4

Divide by 2

X=-2

Y= -2x+1

Y= -2(-2)+1

Y= -4+1

Y= -3

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
