Ineed the answer quick triangle pie is defined by the coordinates (-2, -4), (-6, -0.5), and (0, 4), respectively. the pythagorean theorem to find the lengths of the sides of the triangle. ie= pi= ep=

see below

Step-by-step explanation:

IE = sqrt ( (0-(-6)^2 + (4 - -0.5)^2)

=  sqrt 56.25

= 7.5

PI = sqrt ( (-2 - -6)^2 + (-4 - -6)^2)

= sqrt ( 20)

= 4.47

EP = sqrt((-2)^2 + (-4-4)^2))

= sqrt (68)

= 8.25

IE = 7.5  PI = 4.47 and EP = 8.25

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

addition
