Group like terms then
add like terms
d-2d-10+7=8-10+d
-d-3=-2+d
add d to both sides
-3=-2+2d
add 2 to both sides
-1=2d
divide both sides by 2
-1/2=d
Answer:
I believe the answer is D

Given :
To Find :
the absolute minimum and absolute maximum values of f on the given interval
[-1,2] .
Solution :
Now , getting first order differential equation and equating its equal to zero.

So , x=0 is critical point .
Now , coefficient of
is positive .
Therefore , it is increasing function after x=0 .
So , min value will be at , x=0.

And maximum value will be the maximum at the x=2 because it is increasing function .

Therefore , max and min value is 9 and -3 respectively .
Hence , this is the required solution .
Answer:
24
Step-by-step explanation:
let Sammy's age be x and Lisa y
since Lisa is 4years older than Sammy
