Question 4 Multiple Choice Worth 4 points)
(05.07 MC)
A study analyzed the average yearly salt intake in the United States from 2012 thru 2017. The data is summarized in the table:
Year
Annual Salt Intake
(grams)
2012 3.554
2013 3,598
2014 3 603
2015 3,655
2016 3.718
2017 3.794
The study found that the data after the year 2012 can be modeled by the function f(x) = 52.3x + 3.548, where x is the number of years since 2012 and f(x) is the
total amount of salt ingested in grams Describe the significance of 3.548

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
