Answer:
1) element - a member of a set
2) inequality - <, <, ,
3) line graph - visual tool used to illustrate solution sets
4) real number - positive or negative, rational or irrational numbers including zero
5) set - a collection or group of sets indicated by brackets, {}
6) set builder notation - a shorthand way to write a set
Step-by-step explanation:
The definitions of each of the terms are as follows:
Element: In a set, each member is called its element.
Inequality: The term inequality is used to compare two values. The sign used for inequalities are <, <, , .
Line graph: It gives the solution on a number line. This is the pictorial or visual representation of the solution.
Real number: All numbers that are rational, irrational positive or negative values are called real numbers.
Set: A set is a collection of data that are enclosed in two curly brackets. The data can be numbers, sets, etc.
Set builder notation: It is a shorthand notation used to represent a given set. It defines the data inside the set using appropriate mathematical symbols.
(-9x -1) x (4x+1)
use foil method
-9x * 4x - 9x - 4x - 1
collect like terms by multiplying the -9x and the 4x together, then you add together both -9x and -4x. Then you have your answer below
-36x^2 - 13x - 1
Answer:
<h2>5</h2>
Step-by-step explanation:
Convert both numbers to decimals, then multiply.
1.3333333 x 3.75 = 4.999999 or rounded 5.

Step-by-step explanation:
y= 9/8 * x - 1
The distance between their house and the school from the information given will be 777.60 meters.
<h3>How to calculate the distance?</h3>
The distance between their house and the school will be:
= 80 × 81 × 12
= 77760cm
= 777.60 meters.
When Diane takes 16 min to walk to school, the length of her steps will be:
= 77760/(16 × 90)
= 54 cm
