Remember
aln(c)=ln(c^a)
and
ln(a)-ln(b)=ln(a/b)

so

3ln3-ln9=
ln(3^3)-ln9=
ln27-ln9=
ln(27/9)=
ln3

What is the equation of the ine that has a slope of 4 and passes through the point (3, -10) ?

Schach [20]

Answer:

The answer is

$\huge y = 4x - 22$

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

where

m is the slope

( x1 , y1) is the point

From the question the point is (3, -10) and the slope 4

We have

$y + 10 = 4(x - 3) \\ y + 10 = 4x - 12 \\ y = 4x - 12 - 10$

We have the final answer as

$y = 4x - 22$

Hope this helps you

What is the inverse of f(x)=3x-1

tatiyna

Answer:

$\frac{(y + 1)}{3}$

Step-by-step explanation:

Call $f(x) = y = 3x - 1$

Now, $y + 1 = 3x$

$\implies \frac{y + 1}{3} = x$

This is the inverse of the given function.

You can cross - verify it by substituting a point, say, $(1,3)$

We see that the point satisfies both the equations.
