Sydney wrote the equation y+1=12(x−3). y + 1 = 1 2 ( x − 3 ) . Explain her error and then write the correct equation in point-sl

yanalaym [24]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

Given equation:

$\to y + 1 = 12 ( x - 3 )$

Using formula:

$\to \bold{y = mx +c}$

Solving the given equation:

$\to y + 1 = 12 ( x - 3 )\\\\\to y+1 =12x-36\\\\\to y=12x-36-1\\\\\to y= 12x-37\\\\$

compare the value form the given formula:

$\to m= 12$

Correct equation $\to y= 12x-37$

solpe $\to m= 12$

3. Growth of Cholera bacteria. Suppose that the cholera bacteria in a colony grows unchecked according to the Law of Exponential

Elza [17]

Answer:

2.814 * 10^14

Step-by-step explanation:

For exponential growth:

A = A0*e^kt

A = final amount ; A0 = initial amount ; t = time

Since bacterium doubles ever half hour ;

In 1 hour number of bacterium will be 2² = 4

Hence

Final amount after 1 hour

4 = 1*e^k*1

4 =e^k

Take In of both sides

In(4) = k

Number of bacterium in 24 hours

A = 1*e^In4 * 24

A = e^24In4

A = e^33.271064

A = 281474976710656

A = 2.814 * 10^14

What is the solution to the inequality -4 x < 8?

alekssr [168]

Answer:

The solution of the inequality is x < -2.

Step-by-step explanation:

Let's simplify the inequality first.

=> -4x < 8
=> -4x/4 < 8/4
=> -x < 2
=> x < -2

Hence, the solution of the inequality is x < -2.

Hoped this helped.
