Q

How are the quadrants in a graph set up?

A

Start top right and move counter clockwise.

2
Q

Coefficient

A

a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x y).

3
Q

Degree

A

The squared or cubed. In an equation, the biggest degree is the one that needs to be identified.

4
Q

Convex

A

No dents or indentations in the shape.

5
Q

Concave

A

There are dents or indentations in the shape.

6
Q

Dependent Variable

A

a variable (often denoted by y ) whose value depends on that of another.

7
Q

Independent Variable

A

a variable (often denoted by x ) whose variation does not depend on that of another.

8
Q

Commutative property

A

A math rule that says that the order in which we multiply numbers does not change the product

9
Q

Distributive property

A

When you multiply a factor by two addends, you can first multiply the factor with each addend, and then add the sum.

10
Q

Associative property

A

a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.

11
Q

Triangular prism vs pyramid

A

With a pyramid, all four triangles are the same size. Prisms have sets of two matching triangles with a rectangular base.

12
Q

10^0 equals

A

Middle of all the numbers placed in order.

15
Q

Mode

A

Most frequent value.

16
Q

Range

A

Difference between the highest and lowest number.

17
Q

Prime factorization

A

breaking the number down to prime numbers that when multiplied equal the number. Think of break aparts.

18
Q

Acute

A

less than 90 degrees

19
Q

Obtuse

A

greater than 90 degrees but less than 180 degrees

20
Q

A

Two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

21
Q

Variable

A

a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x, y, and z are common generic symbols used for variables.

22
Q

Terms

A

In the expression, 3a + 8, 3a and 8 are terms.

23
Q

algebraic expression vs equation

A

An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.

24
Q

Commutative property of multiplication

A

AxB=BxA

25
Q

0.7 is 1/1,000 of what number?

A

0.7 x 1,000 = 700

26
Q

monomial

A

one term (3x)

27
Q

binomial

A

two terms (3x + 2)

28
Q

trinomial

A
