On another map the distance between river city and pine bluff is 6 inches. what is the scale of the map?

9. c) Scale: 1 in = miles

Step-by-step explanation:

From the sub part (a), we get that the actual distance between the river city and pine bluff as 9 miles because the scale in sub part (a) is 1 in = 3 miles. Therefore, 3 inches equal 9 miles.

Given:

Actual distance between river city and pine bluff is 9 miles.

Distance on the map is given as 6 inches.

So, 6 inches on map equals 9 miles in actual.

Therefore, 1 inch on map equals miles in actual.

Therefore, the scale of the map is given as:

Scale: 1 in = miles

the answer is 1/4

step-by-step explanation:

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
