Answer:

c) All integers from 10 to 50, inclusive

Step-by-step explanation:

Rauls is selling coupon books.

He started with 50 coupon books and has already won a prize for selling at least 10 coupon books. It means He has a maximum value of 50 coupons and he already sold 10 coupons.He can sell from 10 coupons to 50 coupon books.

The total amount of money Raul will make from selling x coupon books as a function is

f(x) = 20x

The domain of this function is all Real numbers. However, we need a practical domain.Coupon books are integer numbers, 1, 2, 3 we will not have a half book. So, Coupon right now can vary from 10 coupon books to 50 coupon books. It means x can vary from 10 to 50, only integer values and inclusive 10 and 50.

Finally, the answer is C) all integers from 10 to 50, inclusive.

Answer:

Step-by-step explanation:

49x² + 28xy + 4y² ← is a perfect square of the form

(ax + by)² = a²x² + 2abxy + b²y²

49 = 7² ⇒ a = 7 and 4 = 2² ⇒ b = 2

2ab = 2 × 7 × 2 = 28

Hence

49x² + 28xy + 4y² = (7x + 2y)²

with factor 7x + 2y ⇒ C
