A common ratio is basically a ratio of next sequence and the sequence you want

To find a common ratio of geometric sequence, we usually define 'r' as common ratio.

[tex] \displaystyle \large \tt{r = \frac{next \: \: sequence}{the \: \: sequence \: \: you \: \: want} }[/tex]

For example, I want to focus on -14 and the next sequence would be -84.

Hence,

[tex] \displaystyle \large{r = \frac{ - 84}{ - 14} }[/tex]

Thus, r is 6 because both numerator and denominator are negative. negative divides negative = positive.

Or you want to choose -84, then the next sequence would be -504.

[tex] \displaystyle \large{r = \frac{ - 504}{ - 84} }[/tex]

Then r would still be 6. Since both ways have r as 6 and this proves that the sequence is geometric.

Hence, the common ratio is 6.

Answer:

B

Step-by-step explanation:

Answer: Choice B.  (0,4)

Explanation:

Point M is at (0,2). We multiply each coordinate by the scale factor 2 to get (0,4) which is the location of M'

This trick only works if the center of dilation is the origin.

Step-by-step explanation:

multiply 16 by 64

Answer:

<C+83=90 [ sum of complementary angles ]

<C=90-83

<C=7

Now,

<C+83=180 [ sum of supplementary angles ]

<C=180-83

<C=97

Answer:

The answer you are looking for is 27.

Step-by-step explanation:

The reason is because 27 is the 3rd multiple of 9.

Answer:

27

Because

[tex]9 = {3}^{2} \\ 27 = {3}^{3} \\ so. \: \: \: lcm = {3}^{3} = 27[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex] \frac{2}{ \sqrt{3} - 1 } \\ \frac{2}{ \sqrt{3 } - 1} \times \frac{ \sqrt{3} + 1}{ \sqrt{3} + 1} \\ \frac{2 \times ( \sqrt{3} + 1)}{( \sqrt{3} - 1)( \sqrt{3 } + 1) } = \frac{2 \sqrt{3} + 2}{( \sqrt{3} )^{2} - {1}^{2} } \\ \frac{2 \sqrt{3} + 2 }{3 - 1} = \frac{2 \sqrt{3} + 2 }{2} = \frac{2( \sqrt{3} + 1)}{2} \\ \sqrt{3 } + 1 = 1.732 +1 = 2.732[/tex]

[tex] \frac{2}{ \sqrt{3 - 1} } \\ \frac{2}{ \sqrt{2} } \times \frac{ \sqrt{2} }{ \sqrt{2} } = \frac{2 \sqrt{2} }{( \sqrt{2} ) ^{2} } = \frac{2 \sqrt{2} }{2} \\ \sqrt{2} = 1.4142[/tex]

Answer: 13y - 55

Step-by-step explanation:

Given

7 (3y - 5) - 2 (10 + 4y)

Expand parentheses and apply the distributive property

=7 · 3y - 7 · 5 - 2 · 10 - 2 · 4y

=21 y - 35 - 20 - 8y

Move like terms together

=21y - 8y - 35 - 20

Combine like terms

=13y - 55

Hope this helps!! :)

Answer:

[tex]x = -\frac{17}{6} = -2\frac{5}{6}[/tex]

Step-by-step explanation:

When I went through the phase of solving these problems they stumped me SO BAD,... they want you to solve for x,...

Here's your problem:

[tex]-\frac{3}{4} =\frac{3x}{4} +\frac{11}{8}[/tex]

Multiply both sides of the equation by 8, the least common multiple of 4,8. (in doing this you get all the fractions to whole numbers (they are easier to work with))

−6=2×3x+11

Multiply 2 and 3 to get 6

−6=6x+11

Swap sides so that all variable terms are on the left hand side.

6x+11=−6

Subtract 11 from both sides.

6x=−6−11

Subtract 11 from −6 to get −17.

6x=−17

Divide both sides by 6.

x= [tex]\frac{-17}{6}[/tex]

Answer:

A. b+5

B.3(b+5)

C.b+5+8b=9b+5

Step-by-step explanation:

Answer:

coefficient of b

there are 3 b's in this expression so there will be 3 coefficient

in 2ab it will be 2a

in b it will be 1

in -3b2 it will be -3

ccc

so the coefficients are 2a , 1, -3
