Answer:

\boxed {\tt True}

Step-by-step explanation:

This is <u>true.</u> Whenever you divide or multiply an inequality by a negative number, you must flip the inequality sign.

Here is an example:

-9x>27

We have to divide both sides of the inequality by -9. Since it is a negative number, flip the inequality sign.

\frac{-9x}{-9}

x

x

So, it is <em>true</em> that you must flip the inequality sign when multiplying or dividing by a negative number.

The diameter of a bacteria colony that doubles every hour is represented by the graph below. What is the diameter of the bacteri
vlada-n [284]

Option B: 256 is the diameter of the bacteria after 8 hours.

Explanation:

From the given, it is obvious that the graph is an exponential function.

The general formula is given by,

y=a(b)^x

Where a is the initial population,

b is the growth rate and

x is the number of hours.

It is given that the diameter of the bacteria doubles every hour.

Then, we have,

b=2

Let us substitute the coordinate (0,1) and b=2, we get,

1=a(2)^0

1=a

Thus, substituting a=1 and b=2 in the general formula y=a(b)^x, we have,

y=1(2)^x

We need to determine the diameter of the bacteria after 8 hours.

Let us substitute x = 8 in the equation y=1(2)^x, we get,

y=1(2)^8

y=1(256)

y=256

Thus, the diameter of the bacteria after 8 hours is 256

Hence, Option B is the correct answer.

Write and solve a system of equation
erastova [34]
First, write an equation system based on the problem
An equation for "Jami and Mami together had 32" is
⇒ j + m = 32 (first equation)
An equation for "If Mami gives Jami 5, they'll have the same amount"
⇒ m - 5 = j + 5 (second equation)

Second, simplify the equation. I simplify the second equation
m - 5 = j + 5
m = j + 5 + 5
m = j + 10

Third, subtitute m with j+10 in first equation
j + m = 32
j + j + 10 = 32
2j + 10 = 32
2j = 22
j = 11

Fourth, subtitute j with 11 in second equation
m = j + 10
m = 11 + 10
m = 21

Jami had $11, Mami had $21
