Answer:

Step-by-step explanation:

5+6 (2x + 3) -2x = 10x + 23

5 + 6(2x-3) -2x = 10x+23

10x + 23 = 10x + 23

-23 -23

10x = 10x

-10x -10x

0 = 0

Or if you divide will be

10x = 10x / ÷10

X= 1

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.

Express x^2+4x-7 in the form (x+a)^2-b where a and b are integers

lukranit [14]

Answer:

(x + 2)^2 - 11.

Step-by-step explanation:

f(x) = x^2 + 4x - 7

Now x^2 + 4x = (x + 2)^2 - 4 so we have:

f(x) = (x + 2)^2 - 4 - 7

f(x) = (x + 2)^2 - 11.

What is 12 divided by 3 as an algebraic expression

butalik [34]

12/3 or the same thing as ur question but just add a division sign, eg. difference of two and one that would be 2-1
