*70 points and brainliest for a good answer.*

can you me with this one, ? i'm struggling.

graph the piecewise function.

i just need to see if it is an open or closed circle and how far the ray goes.

f(x)=-2/3x +5 if -2
pretty use a graph that goes by 1s and not decimals.

: )

c. side angle side. u shares the same sides

the answer is a.

135 and 80

step-by-step explanation:

i think it would be c

mark brainliest if im right

step-by-step explanation:

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3
