You can solve a system with variables by:

1. Pick any two pairs of equations from the system.

2. Eliminate the same variable from each pair using the Addition/Subtraction method


3. Solve the system of the two new equations using the Addition/Subtraction method


4. Substitute the solution back into one of the original equations and solve for the third variable


5. check by plugging the solution into one of the other three equations

What is the final product? ^5sqrt4x^2 ^5sqrt4x^2
AnnyKZ [126]
For this case we have the following expression:
 ^ 5sqrt4x ^ 2 ^ 5sqrt4x ^ 2
 Rewriting the expression we have:
 ((4x ^ 2) ^ (1/5)) ((4x ^ 2) ^ (1/5))
 For power properties we have:
 (4x ^ 2) ^ (1/5 + 1/5)
 (4x ^ 2) ^ (2/5)
 Rewriting we have:
 (16x ^ 4) ^ (1/5)
 ^ 5sqrt16x ^ 4
 Answer:
 
^5sqrt16x^4

PLLLLLLSSSSSS Help Will Mark Brainlest but must explain what you did in 20 minutes
padilas [110]

Answer:

A) The price of product A is increasing by 3% per year.

(B) The product A recorded a greater percentage change in price over the previous year.

Step-by-step explanation:

(A)

The function representing the price, in dollars, of product A after x years is:

FA(x)=0.69*(1.03)x

The function  FA(x)can be written as:

FA(x)=0.69*1+(0.03)x

The function FA(x) is similar to the exponential growth function, y=a(1+r)x .

Here r is the growth rate.

Thus, it can be said that the price of product A is increasing by 3% per year.

(B)

Consider the data of product B for the year 3 and 4.

The price of product B for year 3 and 4 are 10,303.01 and 10,406.04.

Compute the percent price change from year 3 to 4 as follows:

10406.04-10303.01/10303.01*100

which is 0.999%

~1%

The price of product B is increasing by 1% per year.

Thus, the product A recorded a greater percentage change in price over the previous year.
