27^x = 9^x − 4 Question 1 options: x = 8 x = 4 x = −4 x = −8

Mariulka [41]

Answer:

x = -8

Step-by-step explanation:

Given the equation:

$27^x=9^{x-4}$

Note that

$27=3^3\\ \\9=3^2,$

then

$27^x=(3^3)^x=3^{3x}\\ \\9^{x-4}=(3^2)^{x-4}=3^{2(x-4)}$

Rewrite the equation as

$3^{3x}=3^{2(x-4)},$

then

$3x=2(x-4)\\ \\3x=2x-8\\ \\3x-2x=-8\\ \\x=-8$

Describe the pattern of decay for the sequance.

Georgia [21]

256-192= 64

192-144=48

144-108=36

108-81=27

81- 60.8=20.2

60.8-45.6=15.2

45.6-34.2= 11.4

34.2-25.6=8.6

25.6-19.2= 6.4

19.2-14.4= 4.8

To increase an amount by 3% what single multiplier would you use?<br> thanks :)

KATRIN_1 [288]

X - an amount

$x+3\%x=x+0.03x=1.03x$

To increase an amount by 3% you can multiply the amount by 1.03.
