Answer:

none

Step-by-step explanation:

Because X has the same coefficient on both sides but a different value is being added to it, there cannot be an solution.

9x+3=9x+5

-9x -5

-2=0, which doesnt work so theres no solution

Answer:

This equation doesn't have any solution

Step-by-step explanation:

Given that,

9x +3=9x + 5

Subtract 3 from both sides

9x+3-3=9x+5-3

9x=9x+2

Since 9x cannot be equals to 9x+2, no matter the value of x.

Or further still divide through by 9

9x/9 = 9x/9 + 2/9

x=x + 2/9

it is not possible for x to be equal to x+2/9.

So it doesn't have a solution

x≠x+2/9

At the start of a month, Sasha and Natalia each have a certain amount of money.
Sergio039 [100]

Answer:

Option (A)

Step-by-step explanation:

Sasha has an amount of $400 and saves $20 per week.

If we graph the savings of Sasha, her savings per week will be defined by the slope of the line = $20 per week

Similarly, from the graph attached,

Slope of the line given in the graph = Per week savings of Natalia

Slope of line passing through (0, 190) and (2, 210) will be,

Slope = \frac{y_2-y_1}{x_2-x_1}

          = \frac{210-190}{2-0}

          = 10

Therefore, per week savings of Natalia = $10

Difference in savings of Sasha and Natalia = 20 - 10 = $10 per week

Here, Sasha shows the greater rate of change by $10 per week

Therefore, Option (A) will be the answer.

Which expression is equivalent to ?
mamaluj [8]

Answer:

Step-by-step explanation:

\frac{(a^{2}b^{4}c)^{2}*(6a^{3}b)*(2c^{5})^{3}}{4a^{6}b^{12}c{^3}}\\\\=\frac{a^{2*2}b^{4*2}c^{2}6a^{3}b2^{3}c^{5*3}}{4a^{6}b^{12}c{^3}}\\\\=\frac{a^{4}b^{8}c^{2}6a^{3}b8c^{15}}{4a^{6}b^{12}c{^3}}\\\\=\frac{6*8*a^{4+3}b^{8+1}c^{2+15}}{4a^{6}b^{12}c{^3}}\\\\=\frac{6*2*a^{7}b^{9}c^{17}}{a^{6}b^{12}c{^3}}\\\\=\frac{12a^{7-6}c{17-3}}{b^{12-9}}\\\\=\frac{12a^{1}c^{14}}{b^{3}}\\\\=\frac{12ac^{14}}{b^{3}}

Hint:

x^{m}*x^{n}=x^{m+n}\\\frac{x^{m}}{x^{n}}=x^{m-n},m>n\\\frac{x^{m}}{x^{n}}=\frac{1}{x^{n-m}},n>m

1/3 (12 - 24v) = -2(4v -2)
ANEK [815]
Opening brackets gives;
4-8v=-8v+4
Putting like terms together;
4-4=-8v+8v
0=0
There is no solution thus.
