Evaluate b – 2a – c for a = –7, b = 3, and c = –7.

The answer of the given expression is 24.

Step-by-step explanation:

The given expression is :

We have to evaluate it.

We have been given the values as:

a = –7, b = 3, and c = –7.

Now, substituting these values in the expression we get:

= 24

Therefore, the answer of the given expression is 24.

0 is its x and y coordinate

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
