Triangle ABC with vertices A(4, −6), B(2, −8), and C(−10, 4) is dilated by a scale factor of 2 to obtain triangle A′B′C′. Which statement best describes triangle A′B′C′? It is similar to triangle ABC and has coordinates A′(2, −3), B′(1, −4), and C′(−5, 2). It is similar to triangle ABC and has coordinates A′(8, −12), B′(4, −16), and C′(−20, 8). It is congruent to triangle ABC and has coordinates A′(2, −3), B′(1, −4), and C′(−5, 2). It is congruent to triangle ABC and has coordinates A′(8, −12), B′(4, −16), and C′(−20, 8).

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

a

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
