the negative reciprocal
of the slope of cd.
.
statement
1. ad 1 cd
reason
given
given
2. the slope of ab is -1
the slope of cd is
3. aabd - adbc
the altitude to the hypotenuse forms
similar right triangles.
corresponding sides in similar
triangles are proportional.
5. the negative reciprocal
of cd's slope is
definition of negative reciprocal
6. the slope of ab equals the negative
reciprocal of the slope of cd.

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
