Answer:

The answer is an= 2/3 * 9^n-1

or D

Step-by-step explanation:

The explicit rule is an=a1 * r^n-1

the question tells us that a1 is 2/3, so we plug that into the rule

the question uses the recursive rule ( an=r * an-1) to tell us what r is

r= 9 and a1= 2/3

now lets plug it into our rule

an= 2/3 * 9^n-1

3 (x -1) = 5x +3 -2x

Vika [28.1K]

Steps to solve:

3(x - 1) = 5x + 3 - 2x

~Distribute left side

3x - 3 = 5x + 3 - 2x

~Combine like terms

3x - 3 = 3x - 3

~Subtract 3x to both sides

-3 = -3

~Add 3 to both sides

0 = 0

All real numbers are solutions.

Best of Luck!

Identify the percent of change as an increase or a decrease. 9 points to 4 points

padilas [110]

Answer:

55.55% decrease

Step-by-step explanation:

$change\% = \frac{final \: point \: - initial \: point}{initial \: point \: value} \times 100$

In the question ,

Initial point value = 9

Final point value = 4

Change% = $\frac{4 - 9}{9} \times 100 = \frac{ - 5}{9} \times 100 = - 55.55\%$

Refer to the Venn diagram that represents the sports students chose to play at South High School last year. Select the correct d

vovikov84 [41]

I don't see a diagram, but if the portion of the tennis region you are asked to analyze doesn't intersect anywhere else/any other regions pertaining to other sports, wouldn't the sport chosen by these students be solely tennis?
