Answer:
The first one
Step-by-step explanation:
You You need to make it 5 lb of crawfish so 6$ for 4 pounds is 12$
1 pound is 3$
4 pounds + 1 pound is 15$
Shop a and b is 15$
The amount of the loan after 11 years is $34,113.53 and the intereest earned is $4,113.53
<h3>How to calculate the compound interest</h3>
The formula for calculating the exponential function is expressed as:

Given the following
- P = 30,000
- r = 0.047
- t = 11 years
- n = 4
Substitute into the formula to have:

Hence the amount of the loan after 11 years is $34,113.53
<h3>
Find the interest earned</h3>
Interest = A - P
Interest = 34,113.53 - 30000
Interest = 4,113.53
Hence the intereest earned is $4,113.53

The answer is A( +7) x (-5)
For this case we have the following polynomials:

By subtracting both polynomials we have:

What we must do is subtract terms of the same degree.
We have then:
Answer:
will be a polynomial
Y doesn't vary directly with x
