Answer:
Option D. -3.9 will be the answer.
Step-by-step explanation:
Change in weight of the whale in first week = (-2.1) pounds
Change in weight of the whale in second week = (+0.3) pounds
Change in weight of the whale in 3rd week = (-1.7) pounds
Change in weight of the whale in 4th week = -0.4 pounds
Total change in weight over the period of 4 weeks = - 2.1 + 0.3 - 1.7 - 0.4
= -3.9 pounds
Therefore, Option D. -3.9 will be the answer.
-2.2 - (-1.7) - (-0.4) = -4.2 + 0.3 = -3.9
T12=a-99=106
that's the answer
6x-21=105
+21. +21
6x=126
×=21
21y=75
Divide 21 from 75
Y= 3.6
either (-1,-1) or (-4,-4)
