Essentially, what we need to do here is prove that BE=EC, BE=CB, and.or CE=BC therefore making it isosceles. With ∠AEC=∠DEB, we know AE=DE, so EC=EB (the points go in order). Therefore, as EC=EB, BEC is isosceles (it has at least 2 equal sides).

22's answer is because they're alternate
Answer:

Step-by-step explanation:
Solve for the value of
:

-Take
and subtract it from
:


-Subtract both sides and convert
to a fraction:


Since both
and
have the same denominator, then you would subtract the numerator:


-Multiply both sides by
, which is the reciprocal of
:



-Divide
by
:


So, therefore, the value of
is
.
2 lines intersect at (1,2)
so answer is Yes.
(1,2) is the solution to the system.
The average cost of a two-bedroom apartment in the city will be about $1135
Step-by-step explanation:
The regression line equation is yˆ=1.377x+137.763 where x is the cost of one-bedroom apartment.
Given that the average cost of one-bedroom apartment is $724, then using this value for x
yˆ=1.377*724+137.763 = 1134.711
This value is approximately $ 1135
