Answers

Answer 1

Answer:

2.1

Step-by-step explanation:

You divide 8.4 by 4 hope this helps

Answer 2
Answer:    y = 2.1

=========================================================

Work Shown:

4y = 8.4

4y/4 = 8.4/4  .... divide both sides by 4; division property of equality

y = 2.1

---------------

Check:

4y = 8.4

4*2.1 = 8.4 .... replace y with 2.1

8.4 = 8.4

We end up with a true equation, as we get the same number on both sides, so we've confirmed the answer.

0 solutions because the slopes are the same. The lines will never cross because they are at the exact same angle.

No, I do not agree with Joey because the lines have different slopes and will lead to the system cross which is the solution.

Hello . Please help me with theses Negative exponents please and thank you.

Answers

Answer:

So, to work with negative exponents you need to multiply like a positive exponent, and move the decimal over double the digits place each time.

Examples:

If it is 4 with an exponent of -2, then you will multiply 4 by 4 to get 16, and then move the decimal over double the amount of digits. There are two digits, so you will move the decimal over four digits.

So the answer to 4 with an exponent of -2 would be .0016.
