Expand and simplify (2x+5y) (x-3y)

Dmitry [639]

Should be simple:

Let's take this one at a time.

2x(x-3y)

You'd get:
$2x^2-3xy$
for the first one.

2nd one:
5y(x-3y)
you'd get:
$+5xy-3y^2$

Put them both together:
$2x^2-3xy+5xy-3y^2$

Combine like terms.

Your Answer:
$2x^2+2xy-3y^2$

$= 4 + 12 - 3$

$= 16 - 3$

Use the definition of a derivative to find f’(x).

tatyana61 [14]

Answer:

f'(x) = $-\frac{9}{x^2}$

Step-by-step explanation:

i) f(x) = 9 / x

ii) f'(x) = $$\lim_{h\to 0} \frac{f(x+h) - f(x)}{h} $ \hspace{0.2cm}$

$= $\lim_{h\to 0} \frac{\frac{9}{x+h} - \frac{9}{x} }{h} = \hspace{0.1cm} $\lim_{h\to 0} \frac{9x - 9(x+h)}{hx(x+h)} $ \hspace{0.1cm} = \hspace{0.1cm}$\lim_{h\to 0} \frac{-9h}{hx(x+h)} = $\lim_{h\to 0} \frac{-h}{x(x+h)} = \frac{-9}{x^2}$$
