Andre drew a line connecting two opposite comers of a parallelogram.
select all true statements about the trianoles created by the line
andre drew lesson 1)
a) each triangle has two sides that are 3 units long.
each triangle has a side that is the same length as the diagonal line.
each triangle has one side that is 3 units long.
d.) when one triangle is placed on top of the other and their sides are
aligned, we will see that one triangle is larger than the other.
(e.) the two triangles have the same area as each other.

f

step-by-step explanation:

f

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

sure i'm up for it
