5x + 3 = 3x + 9 what is the value of x

Mathematics
1 answer:
erik [133]3 years ago
7 0

Answer:

x = 3

Step-by-step explanation:

5x + 3 = 3x + 9

subtract 3 on both sides (cancels out 3) (inverse operation)

5x = 3x + 6

subtract 3x on both sides (cancels out 3x) (inverse operation)

2x = 6

divide both sides by 2 (isolates x) (simplifies)

x = 3

Scientist are studying a bacteria sample. The function f(x)=360(1.07)^x gives the number of bacteria in the sample at the end of
Lapatulllka [165]

Options :

A. The initial number of bacteria is 7.

B. The initial of bacteria decreases at a rate of 93% each day.

C. The number of bacteria increases at a rate of 7% each day.

D. The number of bacteria at the end of one day is 360.

Answer:

C. The number of bacteria increases at a rate of 7% each day.

Step-by-step explanation:

Given the function :

f(x)=360(1.07)^x ; Number of bacteria in sample at the end of x days :

The function above represents an exponential growth function :

With the general form ; Ab^x

Where A = initial amount ;

b = growth rate

x = time

For the function :

A = initial amount of bacteria = 360

b = growth rate = (1 + r) = 1.07

If ; (1 + r) = 1.07 ; we can solve for r to obtain the daily growth rate ;

1 + r = 1.07

r = 1.07 - 1

r = 0.07

r as a percentage ;

0.07 * 100% = 7%
