What do the following two equations represent? -3x-y=3 and -3x-y= -2

*40 points*

Step-by-step explanation:

-3x - y = 3

-y = 3x + 3

y = -3x - 3slope is -3...y int = -3

-3x - y = -2

-y = 3x - 2

y = -3x + 2slope is -3...y int = 2

same slopes and different y int's represent PARALLEL LINES <==

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

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
