Answer:

x = 9b/C

Step-by-step explanation:

Cx – 4b = 5b

Add 4b to each side

Cx – 4b+4b = 5b+4b

Cx = 9b

Divide by C

Cx/C = 9b/C

x = 9b/C

x=9b

Step-by-step explanation:

because if you subtract 9-4 it would equal 5 and then you would just add the b to the equation.hope this is helps

Is 1/3, 2/3, 4/3, 8/3, 16/3 arithmetic sequence

11111nata11111 [884]

The given sequence is not arithmetic sequence

Solution:

Given sequence is:

$\frac{1}{3} , \frac{2}{3} , \frac{4}{3} , \frac{8}{3} , \frac{16}{3}$

We have to find if the above sequence is arithmetic sequence or not

An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant

Here in the given sequence

$\text{ first term } = a_1 = \frac{1}{3}\\\\\text{ second term } = a_2 = \frac{2}{3}\\\\\text{ third term } = a_3 = \frac{4}{3}\\\\\text{ fourth term } = a_4 = \frac{8}{3}\\\\\text{ fifth term } = a_5 = \frac{16}{3}$

Let us find the difference between terms

$a_2 - a_1 = \frac{2}{3} - \frac{1}{3} = \frac{1}{3}$

$a_3 - a_2 = \frac{4}{3} - \frac{2}{3} = \frac{2}{3}$

$a_4 - a_3 = \frac{8}{3} - \frac{4}{3} = \frac{4}{3}$

$a_5 - a_4 = \frac{16}{3} - \frac{8}{3} = \frac{8}{3}$

Thus the difference between terms is not constant

So the given sequence is not arithmetic sequence

(X+3) (X-2) Standard form. Please show steps.

Zolol [24]

Use distributive property:

$(x+3)(x-2)=(x)(x)+(x)(-2)+(3)(x)+(3)(-2)\\\\=x^2-2x+3x-6=x^2+x-6$

Write the equation in slope-intercept form y+3=4(x−1) plz do step by step

Rainbow [258]

Answer:y=4x -7

Step-by-step explanation:

The slope intercept form is: y= mx + b

Y+3 = 4(x-1) step one distribute 4

Y+3= 4x - 4 step two subtract 3 from both sides

Y=4x -7

Want Brainliest? Get this correct Which of the following is the quotient of the rational expressions shown below? Make sure your

elena-14-01-66 [18.8K]

Answer:

Step-by-step explanation:

First, notice that we can cancel out an x in the second term. Thus:

$\frac{3x^2}{x^2+x} =\frac{3x^2}{x(x+1)} =\frac{3x}{x+1}$

As with the last question, change the sign to multiplication and "flip" the second term:

$\frac{2x-1}{x+1}\cdot \frac{x+1}{3x}$

Multiply straight across:

$=\frac{(2x-1)(x+1)}{(x+1)(3x)}$

Cancel the (x+1) term:

$=\frac{2x-1}{3x}$

Cannot be simplified further.
