How do you simply -12x=12x into an x='s answer?

Answers

Answer 1
Answer:

-12x = 12x

Start by moving all the terms with the variable you want to solve for on one side of the equation and the rest on the other side of the equation.

We will move 12x to the left side of the equation by subtracting 12x from both sides. Now your equation should look like:

-24x = 0

Isolate the variable x by dividing both sides by -24. Everything divided by 0 is equal to 0, so that means x will be equal to 0.

x = 0

Your answer is x = 0.

Corey needs 24 boards that are 47 1/2 long. How many feet of boards should he buy

Answers

1. 
(24 * 47.5) / 12 = ? 

2. 
8 * 12 = 96 inches 

96 / 47.5 = 2.02 

He can get two 47.50-inch lengths out of each 8-foot board. So he needs 12-foot boards.

Jeremy bought 3,000 milliliters of orange juice. How many liters of orange juice did he buy?

Answers

He bought 3 liters of orange juice becuase 1,000 milliliters are in a liter so if you have 3,000 milliliters you have 3 liters
There are 1000 millilitres (ml) in 1 litre (l)
So if Jeremy bought 3000 ml that is 3 litres
You just divide the amount of ml by 1000 because there are 1000ml in 1l
So the answer is:
3 LITRES

PLEASE HELP ME FAST!The balance in two separate bank accounts grow each month at different rates. The growth rates for both accounts are represented by the functions f(x)=3^x and g(x)=5x+25. In what month is the f(x) balance greater than the g(x) balance? Show your work!​
P.S Whoever gives me a good answer and shows their work I will make as Brainliest!

Answers

Answer:

From fourth month onwards, the growth rate of f(x) is greater than that of g(x).

Step-by-step explanation:

Given:

The growth rates of both bank accounts are given as:

f(x)=3^x\ng(x)=5x+25

Now, as per question, we need to find the value of 'x' when the value of f(x)>g(x). Or,

3^x>5x+25

Now, we can do this by checking the values of 'x' by hit and trial method.

Let x=1. The inequality becomes:

3^1>5(1)+25\n3>30(False)

Let x=2. The inequality becomes:

3^2>5(2)+25\n9>35(False)

Let x=3. The inequality becomes:

3^3>5(3)+25\n27>40(False)

Let x=4. The inequality becomes:

3^4>5(4)+25\n81>45(True)

Therefore, the value of 'x' for which f(x)>g(x) is 4.

So, from the fourth month onwards, the balance in f(x) becomes greater than g(x).

The graphical solution is shown below to support the same.

From the graph, we can conclude that after the 'x' value equals 3.4, the graph of f(x) lies above of g(x). Hence, f(x)>g(x) for x>3.4
