Sin^2 x + 2sin x = 0

10

step-by-step explanation:

7+3=10

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
