1. Exponents are the repeated multiplication of a number. It is represented
by the formula of a^n where a is the number to be repeated and n is the number
of times the number is being multiplies by itself. Also include the sign of the
number, no matter how it is multiplied, it is still important. For instance you have 4(4),
you have 4 as the repeated number. You can see that it is multiplied by itself
by two times. So you have (-4)^2.
2. Graphs and tables are the key features in finding a model between two quantities. If he data values, after plotting it into a graph, produces a straight line, then you will have a direct relationship between the two and sometimes you can get an equation of the line. Sometimes it will give you a curved line. That is why it is important to graph the values of the table to better understand the relationship between two variables.
Answer:
Step-by-step explanation:
the answer is either d or b but i think its d
Answer:
- Disitributive property.
- Addition property of equality.
Step-by-step explanation:
The complete exercise is attached.
For this exercise you need to remember the following properties:
1. The Distributive property states that:
2. The Addition property of equality states that:
Then, given the equation:
You can identify that the first property John used was the Distributive property:
After combining like terms, you can identify that the next property he applied was the Addition property of equality, adding 
to both sides of the equation:
Let x represent the number of the doll.
1.5x=5
x≈3. As a result, they could buy 3 dolls with 5 dollars. Hope it help!
6x + 1 - (2x - 5) =
6x + 1 - 2x + 5 =
4x + 6 <==
