i dont know the answer, but i reccommend using mathpapa.com as they give you the answer PLUS the explaination.
To find the angle use arc tan (-5/-7) which simplifies tips arctan(5/7). arc tan is tan to the power -1, which is also called inverse tan. The heading of the angle, if you drew this out on a graph your angle would be in the third quadrant and therefore the heading is south of west.
Lets say
Jill=J
Meg=m
Beth=b
Jill is 4 years younger than meg so j+4=m
This is because if you add 4 to Jill's age, her age is going to be Megs age
Hope this helps and a brainliest would be appreciated
Answer:
x=5 and y=8
Step-by-step explanation:
Find x:
3x - 2 = x + 8
-x -x
2x - 2 = 8
+2 +2
2x = 10
---- ----
2 2
x = 5
Find y:
6y - 7 = y + 33
-y -y
5y - 7 = 33
+7 +7
5y = 40
---- -----
5 5
y = 8
6m+6n=-30
6m-5n=14
11n=-44
n=-4
m=-1
Ordered pair is (-1,-4)
