According to US News and World Report, 'The average tuition at a four-year public university climbed 15% between 2008 and 2010, fueled by state budget cuts for higher education and increases of 40% and more at universities in states like Georgia, Arizona and California." Secretary of Education, Arnie Duncan, said, “Community colleges... remain one of the most consistently affordable options for higher education: The average net price of a community college increased by less than 1% between 2007 and 2009. Tuition, room and board average $8,085 at a public, two-year institution in 2010. The data table and graph shown on the next page reflect the information from this article. Use this information to answer the following questions. Look at the average costs for four-year public universities, four-year private universities, and 2 year public universities shown in the data table. Look at the best-fit lines drawn for average tuition costs from 2000 through 2010. A) Calculate the slope of each of the following lines
Public 4-Year...
Private 4-Year
Public 2-year​

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

is there more to this question?

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

-3 degrees
