How do you solve this equation 3^3x-7=81^12-3x

slavikrds [6]

I think you meant...

3^(3x-7)=81^(12-3x) (note that 81=3^4) so

3^(3x-7)=3^4^(12-3x)

3^(3x-7)=3^(48-12x) taking log or natural log of both sides show that

3x-7=48-12x

15x=55

x=11/3

You can divide other shapes into triangles. Then you use what you know about the similar or congruent angles/sides (depending on your question) to determine congruency/similarity between other shapes.

What is the slope of the line that passes through the pair of points (1/3, -1) and ( -2, 9/2)

UkoKoshka [18]

Answer:

$\boxed{m = - \frac{33}{14} }$

.

Step-by-step explanation:

Use the form below

$\boxed{\boxed{m = \frac{y_2 - y_1}{x_2 - x_1} }}$

Where

$m$ is a slope
$(x_1,~y_1)$ and $(x_2,~y_2)$ are the point of the line

.

So, the slope is

$(\frac{1}{3} ,~ -1) \to x_1 = \frac{1}{3} ~and~y_1 = -1$

$(-2,~ \frac{9}{2} ) \to x_2 = -2~and~y_2 = \frac{9}{2}$

.

$m = \frac{\frac{9}{2} -(-1)}{-2-\frac{1}{3} }$

$m = \frac{\frac{11}{2} }{\frac{-7}{3} }$

$m = \frac{11}{2} \div (-\frac{7}{3} )$

$m = \frac{11}{2} \times (-\frac{3}{7} )$

$m = - \frac{33}{14}$

.
