The point means that 15 pounds of beans cost 12 dollars.
Answer: 7%
Step-by-step explanation:
Given: Initial jobs = 428.5 thousand
Average rate of declining of jobs from 2010 to 2020 = 3 thousand jobs per year
From 2010 to 2020 , there are 10 years.
Total jobs declines till 2020 = 10 x (3 thousand)
= 30 thousand (Change in jobs)
Now, utilities percent change for 2010 to 2020 : 
Utilities percent change for 2010 to 2020 = 7 %

Step-by-step explanation:
Part B was solved using a graphing calculator
Step-by-step explanation:
factor 4 out of the variable terms, as this helps.
but my approach is simply to define the target and then calculate "backwards".
we want to find
(ax + b)² = a²x² + 2abx + b²
and now we compare with the original equation :
a²x² = 4x²
a² = 4
a = 2
2abx = 16x
2×2×bx = 16x
4b = 16
b = 4
b² = 16, but we have only 3, so we need to subtract 16-3 = 13 from the completed square.
so, our equation is
(2x + 4)² - 13 = 0
(2x + 4)² = 13
2x + 4 = sqrt(13)
2x = sqrt(13) - 4
x = sqrt(13)/2 - 2
