The image of polygon mnop after a similarity transformation is polygon wxyz each side of mnop is two times as long as the corresponding side of wxyz what is the scale factor of the dilation in the similarity transformation

2

Step-by-step explanation:

Given : The image of polygon MNOP after a similarity transformation is polygon WXYZ each side of MNOP is two times as long as the corresponding side of WXYZ .

i.e.    [ Since MN corresponds WX ]

We know that for any two similar geometric figures,  the scale factor is the ratio of their corresponding sides .

i.e.

Hence, the  the scale factor of the dilation in the similarity transformation =2

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
