Answer:
last one
Step-by-step explanation:
3y=8x
Explanation:
If y varies directly with x then
y=c⋅x for some constant of variation c
If (x,y)=(14,23) is a solution to this equation, then
23=c⋅14
→c=23⋅41=83
So
y=83x
or (clearing the fraction)
3y=8x
Answer:
x=-1
Step-by-step explanation:
1.) 2-3(2x-1)=-6x+5
2.) -1(-2x-1)=-6+5
3.) (2x+1)=-6+5
4.) (2x+1)=-1
5.) 2x=-2
6.) x=-1
Answer:
e^xsinx · (sinx+xcosx)
Step-by-step explanation:
f'(x)=e^xsinx · (xsinx)'= e^xsinx · (sinx+xcosx)
