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.

edward deposited ​$7,500 into a savings account 5 years ago. The simple interest rate is 5​%. How much money did earn in​ interest?

Answers

Answer:

Edward earned $1,875 in interest.

Step-by-step explanation:

The formula for simple interest is i = prt, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.

Here, p = $7,500, r = 0.05 and t = 5 years, and so the interest earned was

i = ($7,500)(0.05)(5) = $1,875.

Select all of the ordered pairs (x,y) that are solutions to the linear equation 2x+3y=6. Substitute the x and y values into the equation above to see if the ordered pair is a solution to the linear equation.

Answers

Answer:

1. Not a solution

2. Not a solution

3. Not a solution

4. Not a solution

5. A Solution

6. A solution

Step-by-step explanation: 5 is correct because it is 3 times 2 so 6, but there is no y so the final answer is 6. And the last one is 6 x 2 = 12 and then -2 x 3 = - 6, so 12 - 6 = 6.

Hope this helps

Answer:

The fifth and sixth answer are solutions.

Step-by-step explanation:

If you substitute the x and y values, essentially multiplying them by the already existing coefficents, you realize that a lot of the equations do not equal 6.

The last two however, do.

Answers

Answer:

2.1

Step-by-step explanation:

You divide 8.4 by 4 hope this helps

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.
