Answer:
a. 40
b. 0
c. 50
Step-by-step explanation:
a) 46 + (-2k) for k = 3 is ...
46 + (-2(3)) = 46 -6 = 40
__
b) 46 + (-2k) for k = 23 is ...
46 + (-2(23)) = 46 -46 = 0
__
c) 46 + (-2k) for k = -2 is ...
46 + (-2(-2)) = 46 +4 = 50
which means either
or
. The equation has no solution, since
is always bounded between -1 and 1. The second has one solution at
, and any number of complete revolutions will also satisfy this equation, so in general the solution would be
where
is any integer.
So you could choose
and
.
I believe the answer is A
Answer:
They are congruent by the AAS theorem!
Step-by-step explanation:
Sides EF and HJ are congruent, angles E and J are congruent and angles EGF and HGJ are congruent because they are vertical angles. Therefore, the triangles are congruent by the AAS theorem!
Hope this helps you :)
