Solve??????????? 4 and 5

1 answer:

4 0

4) Solve for x using y = x - 4.
x = y + 4
Now plug x in to y = 6x - 10.
y = 6(y + 4) - 10
y = 6y + 24 - 10
y = 6y + 14
-5y = 14
y = -14/5
Plug y back in to x = y + 4.
x = -14/5 + 4
x = 1.2
(6/5, -14/5)

5) Make the expressions equal to each other.
2x + 3 = 3x - 6
9 = x
x = 9

Differentiate. y = ln(t)/t²

azamat

Remember

the deritivive of f(x)/g(x)=(f'(x)g(x)-g'(x)f(x))/((g(x))^2)

deritivive of lnx is 1/x
derivitive of t^2=2t

so

$\frac{(1/t)t^2-2tlnt}{(t^2)^2}$ =
$\frac{t-2tlnt}{t^4}$ =
$\frac{1-2ln(t)}{t^3}$
