Hey!

Let's start writing this problem.
-2x+7=13x-5
Subtract 7 from both sides.
-2x+7-7=13x-5-7
-2x=13x-12
Subtract 13x from both sides.
-2x-13x=13x-12-13x
-15x=-12
Divide both sides by -15.
\frac{-15x}{-15}=\frac{-12}{-15}
x=\frac{4}{5}

Let me know if you have any questions regarding this problem!
Thanks!

<span>-2x+7=13x-5
13x + 2x = 7 + 5
15x = 12
    x = 12/15
    x = 4/5</span>

Find the generating function for the sequence 1,-2,4,-8, 16, ...
kirill [66]

Answer:

  a(x)=\dfrac{1}{1+2x}

Step-by-step explanation:

The generating function a(x) produces a power series ...

  a(x)=a_0+a_1x+a_2x^2+a_3x^3+\dots

where the coefficients are the elements of the given sequence.

We observe that the given sequence has the recurrence relation ...

  a_0=1;a_n=-2a_{n-1} \quad\text{for n $>$ 0}

This can be rearranged to ...

  a_n+2a_{n-1}=0

We can formulate this in terms of a(x) as follows, then solve for a(x).

\sum\limits^{\infty}_{n=1} {a_{n}x^n} =a(x)-a_0 \quad\text{and}\\\\\sum\limits^{\infty}_{n=1} {2a_{n-1}x^n} =(2x)a(x) \quad\text{so}\\\\\sum\limits^{\infty}_{n=1} {(a_n+2a_{n-1})x^n}=0=a(x)-a_0+2xa(x)\\\\a(x)=\dfrac{a_0}{1+2x}=\dfrac{1}{1+2x}

The generating function is ...

  a(x) = 1/(1+2x)

By what percent will a fraction increase if its numerator is decreased by 30%
Nadya [2.5K]

Answer:

40%

Step-by-step explanation:

Let x = numerator

Let y = denominator

\implies \dfrac{x}{y}

Decreased by 30% = 100% - 30% = 70% = 70/100 = 0.7

Decreased by 50% = 100% - 50% = 50% = 50/100 = 0.5

\implies \dfrac{0.7x}{0.5y}

\implies \dfrac{0.7}{0.5}=1.4

\implies 1.4 \ \dfrac{x}{y}

1.4 as a percentage = 1.4 x 100 = 140%

Therefore, the percentage increase is 140 - 100 = 40%
