-x + (−3) = x + 3 ​

Answers

Answer 1
Answer:

Step-by-step explanation:

-x - 3 = x + 3

Solving like terms

-3 - 3 = x + x

-6 = 2x

-6 / 2 = x

-3 = x
Answer 2
Answer:

Answer:

-3

Step-by-step explanation:

You are trying to solve for x in this situation. So the first thing you want to do is choose a side (it doesn't matter in this situation bc there is an x on either side of the =) and isolate the x.

**I'm going to choose the left side cause why not** Add the -3 to both sides to get -x by itself:

-x + (−3) = x + 3

-x -3= x+3

* quick side note,  when you add a negative number to a positive, it has the same effect as subtracting

-x=x+6

Now -x is by itself but there is still another x, so combine like terms again:

-2x=6

Now simplify by dividing -2 to both sides:

x=-3

(4.3x10^8)x(2.0x10^6) how would you solve this and express it in scientific notation?

Answers

8.6x10¹⁴ is the value of (4.3x10⁸)x(2.0x10⁶) in scientific notation.

What is Number system?

A number system is defined as a system of writing to express numbers.

The given expression is (4.3x10⁸)x(2.0x10⁶)

We need to express  it in scientific notation

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.

Firstly let us multiply four point three with two point zero

4.3×2

Which given 8.6

Now 8.6x10⁸x10⁶

When the bases are same then the powers will be added

8.6x10¹⁴

Hence, 8.6x10¹⁴ is the value of (4.3x10⁸)x(2.0x10⁶) in scientific notation.

First, you would multiply 4.3 and 2.0 together to obtain 8.6. After that if both of the numbers have 10 to the power of whatever number, you can add the exponents together. In this case, you would get 14. Your final answer is 8.6x10^14.

A group of Physicians must build an addition to their existing private clinic. They are considering three different sized additions; a small addition, a medium addition and a large addition. If the medical demand is high (there is a favorable market for the addition) they would realize a net profit of $100,000 with a large addition, a net profit of $40,000 with a medium addition and a net profit of $10,000 with a small addition. If the medical demand is low (there is an unfavorable market for the addition) they would realize a net loss of $40,000 with the large addition, a net loss of $10,000 with the medium addition and a net profit of $5,000 with the small addition. The Physicians were also able to assign the following utility preference values to each of the potential payoffs they could encounter. Utility of $100,000 is 1.0, U ($40,000) is 0.9, U ($10,000) is 0.6, U ($5,000) is 0.5, U ($-10,000) is 0.4, and U ($-40,000) is 0.0. The physicians also have a reliable forecast indicating a 40% probability of the high medical demand. Using expected monetary value theory, what should they do and what is the expected value of that decision? Using expected utility theory, what should they do and what is the expected utility of that decision?
