Answer:

x = -5

Step-by-step explanation:

4 - 2(x+7) = 3(x+5)

4 - 2*x - 2*7 = 3*x + 3*5

4 - 2x - 14 = 3x + 15

4 - 14 - 15 = 3x + 2x

-25 = 5x

x = -25/5

x = -5

Check:

4 - 2(-5+7) = 3(-5+5)

4 - 2*2 = 3(0)

4 - 4 = 0

Answer:

x = -5

Step-by-step explanation:

4-2(x+7)=3(x+5)

Distribute

4 -2x-14 = 3x+15

Combine like terms

-2x-10 = 3x+15

Add 2x to each side

-2x-10+2x= 3x+15+2x

-10 = 5x+15

Subtract 15 from each side

-10-15 = 5x+15

-25 = 5x

Divide by 5

-25/5 = 5x/5

-5 =x

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%

#9. Solve: 8x + 5 = 3x + 15<br><br> X = 4<br> x = 2<br> x = 20/11<br> x = 20
Jobisdone [24]

Answer:

x = 2

Step-by-step explanation:

8x + 5 = 3x + 15

8x - 3x + 5 = 3x - 3x + 15

5x + 5 = 15

5x + 5 - 5 = 15 - 5

5x = 10

5x / 5 = 10 / 5

x = 2
