Answer:

C. $5x=25$

Step-by-step explanation:

Given:

$2x-3y=-1\\3x-3y=26$

Add the two equations, we get

$2x-3y+3x+3y=-1+26\\(2x+3x)+(-3y+3y)=25\\5x+0=25\\5x=25$

Therefore, the correct option is option C.

How is the sum expressed in sigma notation? 1/64+1/16+1/4 + 1 + 4

Answer:

sum = ∑[n=1,5] 4^(n-4)

Step-by-step explanation:

First of all, you need to be able to describe the n-th term.

Here, we have ...

term #: 1, 2, 3, 4, 5

value: 4^-3, 4^-2, 4^-1, 4^0, 4^1

That is, the exponent of 4 is 4 less than the term number. So, the n-th term is 4^(n-4). The sum of the 5 terms shown is then ...

$\displaystyle sum=\sum_{n=1}^5{4^{n-4}}$
