Answer:

only 3, A with B B with C and A with C, but if you can use the same 2 if reversed it would be 6, for it would be A with B, B with A, C with B, B with C, A with C, and C with A.

Answer:

Step-by-step explanation:

We can choose three ways:AB, AC, BC, as the order is not important.

Or you can calculate 3C2=(3×2)/(1×2)=3

What is the solution of log 2 (3x-7) = 3

wel

$\bf \textit{Logarithm Cancellation Rules} \\\\ log_a a^x = x\qquad \qquad \stackrel{\textit{we'll use this one}}{a^{log_a x}=x} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \log_2(3x-7)=3\implies 2^{\log_2(3x-7)}=2^3\implies 3x-7=2^3\implies 3x-7=8 \\\\\\ 3x=15\implies x=\cfrac{15}{3}\implies x=5$

What equation can be written from this sequence? -50, -33, -16, 1

Kaylis [27]

-50 + 17 = - 33
-33 + 17 = -16
- 16 +17 =1

This is arithmetic sequence, where 1st term is -50,
and common difference is 17.
Formula for the term of arithmetic sequence
a(n) = a(1) +d(n-1) = -50 +17(n-1) = -50 +17n - 17 = -67 +17n

So, we can write a formula
a(n) = -67 +17n
