You should first draw a strait line across your paper. Draw the 55 degree angle with your protractor. Then draw the 125 degree angle it should stop at where the line of the 55 degree angle you just drew. These two angles add up to 180 degrees. 125+55 = 180. These are known as supplementary angles.
Answer:
True
Step-by-step explanation:
Since the rule is (x, y) ---> (x - 3, y - 4), you would subtract 3 from 0 (the x value of A) which would be -3. Then subtract 4 from 7 (the y value of A), which would be 3. So the answer would be true, that A' would be (-3, 3).
S = # of salads
d = # of drinks
$6.5s + $2d = $836.5
s + d =209
1. Isolate a variable.
s = 209-d
2. Plug in.
6.5 (209-d) + 2d = 836.5
1358.5 - 6.5d + 2d = 836.5
-4.5d = -522
d = 116

Answer:
Step-by-step explanation:
so it's a little hard to tell if they mean
or 
for for answer D but i'll guess that they mean the latter.... also for B... it's often said... incorrectly that you can't take the square of a negative number.. but that's not exactly true. b/c 
= i in the imaginary number world. soooo that said... I think they are assuming that you don't know you could do that.. even thou.. now you do :D but.. B looks like the best choice
