Answer:
x=-17, y=5. (-17, 5).
Step-by-step explanation:
-2x-5y=9
3x+11y=4
---------------
3(-2x-5y)=3(9)
2(3x+11y)=2(4)
---------------------
-6x-15y=27
6x+22y=8
-----------------
7y=35
y=35/7
y=5
3x+11(5)=4
3x+55=4
3x=4-55
3x=-51
x=-51/3
x=-17

The picture is not clear. let me assume
y = (x^4)ln(x^3)
product rule :
d f(x)g(x) = f(x) dg(x) + g(x) df(x)
dy/dx = (x^4)d[ln(x^3)/dx] + d[(x^4)/dx] ln(x^3)
= (x^4)d[ln(x^3)/dx] + 4(x^3) ln(x^3)
look at d[ln(x^3)/dx]
d[ln(x^3)/dx]
= d[ln(x^3)/dx][d(x^3)/d(x^3)]
= d[ln(x^3)/d(x^3)][d(x^3)/dx]
= [1/(x^3)][3x^2] = 3/x
... chain rule (in detail)
end up with
dy/dx = (x^4)[3/x] + 4(x^3) ln(x^3)
= x^3[3 + 4ln(x^3)]
i think you can do this one : )
Answer:
Neither even nor odd.
Step-by-step explanation:
f(x) = 2(x + 1)^3 = 2x^3 + 18x^2 + 54x + 54
f(-x) = -2x^3 + 18x^2 - 54x + 54
If it was even f(x) would be = f(-x) so it is NOT EVEN.
-f(x) = 2x^3 - 18x^2 + 54x - 54
So f(-x) is not = -f(x) so it is not ODD either.
