Answer : x >= -7


On simplifying,

2x - 8 - 9x  <=  -4x + 13

-7x - 8 <= -4x + 13

-3x - 8 < = 13

-3x <= 21

x >= -7

Make denomenators the same

times left denomenator by (x+3)/(x+3) and right one by (x-9)/(x-9)

\frac{3(x+3)}{(x-9)(x+3)}+  \frac{5(x-9)}{(x-9)(x+3)}=
\frac{3(x+3)+5(x-9)}{(x-9)(x+3)}=
\frac{3x+9+5x-45}{(x-9)(x+3)}=
\frac{8x-36}{(x-9)(x+3)}

if expandded we get
\frac{8x-36}{x^2-6x-27}

I need someone to explain how to solve this please!
Paladinen [302]

(x+3)/2x+5 + (3x-5)/(3x+5)

LCM = ( 2x+5)( 3x+5)

[( x+3)( 3x+5) + ( 3x -5)( 2x+5)]/( 2x+5)( 3x+5)

= (3x^2 + 5x +9 x +15 + 6x^2 + 15x -10x -25)/( 2x+5)( 3x+5)

=( 9 x^2 + 19x -10)/( 2x +5)(3x+5)

The table represents an exponential function.
kkurt [141]

Answer:

b=2/3

Step-by-step explanation:

The table is given as:

\left|\begin{array}{c|c}x&y\\--&--\\1&9\\2&6\\3&4\\4&\dfrac83\\\\5&\dfrac{16}{9}\end{array}\right|

The exponential function is given in the form

y= a (b)^{x}

where a is the initial value and b is the multiplicative rate of change

When  x=1, y=9, we have:

9= a (b)^{1}

When  x=3, y=4, we have:

4= a (b)^{3}

Dividing the two equations:

\dfrac{a (b)^{3}}{a (b)^{1}} =\dfrac{4}{9} \\b^2=\dfrac{4}{9}\\b=\sqrt{\dfrac{4}{9}} \\b=\dfrac{2}{3}

The multiplicative rate of change, b is 2/3.
