Looking at the given diagram, angle AEC and angle DEB share the same vertex, E. They are described as vertically opposit angles. In geometry, vertically opposite angles are equal. This means that

Angle DEB = angl AEC = 50 degrees

Y = -2x - 5

lions [1.4K]

Answer:

A. One line

Step-by-step explanation:

Let rearrange the system of equations into explicit forms:

$y = -2\cdot x - 5$

$6\cdot x + 3\cdot y = -15$

$3\cdot y = -6\cdot x - 15$

$y = -2\cdot x - 5$

The second equation is identical to the first one, which means that there is just one line.

Is the sequence geometric? if so, identify the common ratio 1/5,2/15,4/45,8/135,16/405,...

Romashka-Z-Leto [24]

So have the sequence: $\frac{1}{5} , \frac{2}{15} , \frac{4}{45} , \frac{8}{135} , \frac{16}{145} ,...$
To check if the sequence is geometric, we are going to find its common ratio; to do it we are going to use the formula: $r= \frac{a_{n} }{a_{n-1}}$
where
$r$ is the common ratio
$a_{n}$ is the current term in the sequence
$a_{n-1}$ is the previous term in the sequence
In other words we are going to divide the current term by the previous term a few times, and we will to check if that ratio is the same:

For $a_{n}= \frac{2}{15}$ and $a_{n-1}= \frac{1}{5}$ :
$r= \frac{ \frac{2}{15} }{ \frac{1}{5} }$
$r= \frac{2}{3}$

For $a_{n}= \frac{4}{45}$ and $a_{n-1}= \frac{2}{15}$ :
$r= \frac{ \frac{4}{45} }{ \frac{2}{15} }$
$r= \frac{2}{3}$

For $a_{n}= \frac{8}{135}$ and $a_{n-1}= \frac{4}{45}$ :
$r= \frac{ \frac{8}{135} }{ \frac{4}{45} }$
$r= \frac{2}{3}$
As you can see, we have a common ratio!

We can conclude that our sequence is a geometric sequence and its common ratio is $\frac{2}{3}$
