When log2 3 = d is turned to exponential form it is 2^d = 3
then do algebra where d = 3/2
d = 1.5
log2 3 = 1.5
then log2 72 = 1.5 squared + 3
log2 72 = 5.25

Solve for x:<br><br> a<br><br> 3<br> b<br><br> 9<br> c<br><br> 1.5<br> d<br><br> 13.5

Hi there! :)

\large\boxed{\text{ x = 9}}

The two angles pictured are vertical angles, therefore:

8x - 6 = 6x + 12

Solve for x by subtracting 6x from both sides:

2x - 6 = 12

Add 6 to both sides:

2x = 18

Divide both sides by 2:

x = 9.

The average rate of change of a function f(x) = x2 between x = 3 and x = 9 is
masya89 [10]

Answer:

12.

Step-by-step explanation:

Average rate of change = (value of the function when x = 9 - value when x=3)

/

(9 - 3)

= f(9) - f(3) / (9-3)

= (9^2 - 3^2) / (9-3)

= 72 / 6

=  12.
