how do I convert -15 4/9 to a decimal?

Answers

First you divide 100 by the denominator, which in this case, is 9. Whatever number you get, you multiply that by the numerator, which is 4. I got -15.444444. The 4 repeats.

Answer:

-15.44...

Step-by-step explanation:

Well the -15 is a whole number so it stays on the left of the decimal. Then you divide 4 by 9 and get 0.4444... Lastly you just add them together.

Hope this helps!

How do I simplify radicals?

Answers

Answer:

Step 1: Find the prime factorization of the number inside the radical. Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Click on the link to see some examples of Prime Factorization. Also factor any variables inside the radical.

Step 2: Determine the index of the radical. The index tells you how many of a kind you need to put together to be able to move that number or variable from inside the radical to outside the radical. For example, if the index is 2 (a square root), then you need two of a kind to move from inside the radical to outside the radical. If the index is 3 (a cube root), then you need three of a kind to move from inside the radical to outside the radical.

Step 3: Move each group of numbers or variables from inside the radical to outside the radical. If there are nor enough numbers or variables to make a group of two, three, or whatever is needed, then leave those numbers or variables inside the radical. Notice that each group of numbers or variables gets written once when they move outside the radical because they are now one group.

Step 4: Simplify the expressions both inside and outside the radical by multiplying. Multiply all numbers and variables inside the radical together. Multiply all numbers and variables outside the radical together.

Example:

Example 1 – Simplify: Example 1

Step 1: Find the prime factorization of the number inside the radical.

252=2*2*3*3*7

Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind.

√252= √2*2*3*3*7

Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical.

2*3√7

Step 4: Simplify the expressions both inside and outside the radical by multiplying.

Which statement explains whether y = 4x + 8 is a linear function or a nonlinear function?

1. It is a linear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are on a straight line.

2. It is a nonlinear function because the graph contains the points (8, 0), (12, 1), (16, 2), which are not on a straight line.

3. It is a linear function because the graph contains the points (0, 8), (1, 12), (2, 16), which are on a straight line.

4. It is a nonlinear function because the graph contains the points (0, 8), (1, 12), (2, 16), which are not on a straight line.

Answers

Answer:

3 (linear)

Step-by-step explanation:

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1

for each of its variables. In this case, the degree of variable y is 1

and the degree of variable x is 1

The correct answer is 3.

So i'm having difficulty understanding this "When multiplying the same base raised to an exponent __ the base and __ the exponents" Please help i do not understand this.

Answers

When multiplying two exponential expressions with the same base, the product has the same base with an exponent that is the sum of the exponents of the factors.

Answer:

When multiplying the same base raised to an exponent, keep the base and add the exponents.

Step-by-step explanation:

The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.

I hope this helped you understand more!
