Answer:

$\textsf{A)} \quad 5u^3-2u^2+5u+8$

Step-by-step explanation:

Given expression:

$(-2u^3+5u-1)+(7u^3-2u^2+9)$

Remove parentheses:

$\implies -2u^3+5u-1+7u^3-2u^2+9$

Collect like terms:

$\implies -2u^3+7u^3-2u^2+5u-1+9$

Combine like terms:

$\implies 5u^3-2u^2+5u+8$

Which is the best example of a down payment?

Maru [420]

Answer:

C

Step-by-step explanation:

Proof by some contradictions:

D is not a good example because she does not pay anything upfront

B is not a good example because he pays <u>everything </u>upfront with some of the money from a third party

A is not right because the 500 is a security deposit, which is a different concept from a down payment

Therefore the answer should be C, where money is payed upfront and payed after he receives the product.

Please help me on this math problem

Fed [463]

We know the first term is 16, because f(1) = 16. Next, we can use the recursive rule provided. f(3)=1/2*f(3-1). This gives us f(3)=1/2*f(2). We know f(2) is 8. We know have f(3)=1/2*8. This is 4.

The answer is 16, 4.
