We should substitute each and check in this case:
The maximum value can only be -3
is 4 - 2(2) ≤ -3 ?
Lets check:
4 - 4 ≤ -3
0 ≤ -3 ⇔ this is wrong
The solution is the last one because:
-1 - 2(1) ≤ -3
-3 ≤ -3
(1,-1)

Answer:
the 4th one, hop this helps sorry if I wasn't right.
Answer:
a should be 45
b should be 90
c should also be 45
Step-by-step explanation:
I know this because 180-135=45 for a
since c is also 45, beside c should be 135.
which means those angles are congruent.
since a triangle equals 180 degrees all together 180-45-45=90
so b is 90
