Answer:

x=4.375

Step-by-step explanation:

-3(2x-7)+5=2x-9

-6x+21+5=2x-9

-6x+26=2x-9

-6x-2x+26=2x-2x-9

-8x+26=-9

-8x+26-26=-9-26

-8x=-35

-8x/-8=-35/-8

Answer: 35/8     or     4\frac{3}{8}

<u>Simplify each term</u>

<u></u>-3(2x)-3-7+5=2x-9<u></u>

<u></u>-6x-3-7+5=2x-9<u></u>

<u></u>-6x+21+5=2x-9<u></u>

<u></u>-6x+26=2x-9<u></u>

<u></u>

<u>Move all terms containing x to the left side of the equation</u>

<u></u>-6x+26-2x=-9<u></u>

<u></u>-8x+26=-9<u></u>

<u></u>

<u>Move all terms not containing x to the right side of the equation.</u>

<u></u>-8x=-9-26<u></u>

<u></u>-8x=-35<u></u>

<u></u>

<u>Divide each term by − 8 and simplify.</u>

<u></u>-8x/-8=-35/-8<u></u>

<u></u>

<u>Note</u>

Dividing 2 negative will give you a positive answer.

x=35/8

Which shows the following expression after the negative exponents have been eliminated? xy^-6/x^-4 y^2, x=/0 y=/0
makvit [3.9K]
The expression would be \frac{x^5}{y^8} after the negative exponents have been removed.

A negative exponent basically tells us to "flip" the side of the fraction it's on.  This means that y⁻⁶ on the numerator would go to the denominator, and that x⁻⁴ on the denominator would go to the numerator.  This gives us:

\frac{x\times x^4}{y^2\times y^6}=\frac{x^5}{y^8}

torisob [31]

Answer:

Step-by-step explanation:

This is a super simple question. All you have to know is how much money will be charged a month, and how many months there are in a year. Just simply multiply 7 by 12 as the streaming service is charging 7 dollars a month and there are 12 months in a year. After you multiply the two numbers, you should end up with 84 dollars charged after 1 year.
