Answer:

Step-by-step explanation:

they are saying when -49 = -12x +47 what is x

so solve for x

-49-47 = -12x

-96 = -12x (b/c there are two negative signs they cancel out )

$\frac{96}{12}$ =x

8 = x

:) so when you input an 8 you get out a -49

In how many ways can five basketball players be placed in three positions?

Georgia [21]

Answer:

10 ways

Step-by-step explanation:

The number of ways in which five basketball players could be placed in three positions is:

5 $C_{3}$ = $\frac{5!}{(5-3)!3!}$

= $\frac{5!}{3!2!}$

= $\frac{5*4*3*2!}{3*2*2!}$

= 5 × 2

= 10

The basketball players can be arranged in 10 ways.

Express each logarithm in terms of In 2 and In 5.

Sladkaya [172]

Answer:

$5ln2-3ln5$

$2ln5-ln2$

Step-by-step explanation:

∵ $32=2^{5}$

∵ $125=5^{3}$

∵ $ln\frac{32}{125}=ln\frac{2^{5}}{5^{3}}$

∴ $ln2^{5}-ln5^{3}=5ln2-3ln5$

∵ $12.5=\frac{125}{10}=\frac{25}{2}=\frac{5^{2}}{2}$

∴ $ln12.5=ln\frac{5^{2}}{2}$

∴ $ln5^{2}-ln2=2ln5-ln2$
