Answer:
no solutions
Step-by-step explanation:
Subtract the two equations
3x+y=18
-(3x+y=16)
--------------------
0 + 0 = -2
0 does not equal negative 2
This is never true so there are no solutions
I believe it’s 22 Bc it’s not too much bigger than “18” so it should be around 22-24
Answer:
Step-by-step explanation:
Point B is 6 units below and 4 units to the right of A, so the slope is ...
slope = (change in y)/(change in x) = -6/4 = -3/2
Point R corresponds to point B, so will be 6 units below and 4 units to the right of point Q.
R = Q + (4, -6) = (2, -4) + (4, -6) = (2+4, -4-6)
R = (6, -10)
4x+2y i hope that helps :3
1st week - Lost 3 pounds = +3
2nd week - Gained 1 pound = -1
3+13 = + 22
So 22+3 = 25 25-1 = 24
So Tina lost 24 pounds in 13 weeks.
