Front

Which property allows the last question to be written as 7 + 5x or 5x + 7?

Back

Commutative Property: This property states that the order in which two numbers are added does not change the sum.

Front

What is the value of x in the equation 4(x - 7) = 0.3(x + 2) + 2.11?

Back

x = 8.3

Front

Using the substitution method, which equivalent equation could Vito use for the system of equations y + 3x = -4 and 2x - 3y = -21?

Back

2x - 3(-3x - 4) = -21

Front

Which point lies on the graph represented by the equation 4y + 3x = 8?

Back

(4, -1) is a point on the graph.

Front

What is the slope of the line whose equation is 5x + 2y = 6?

Back

Front

What is the definition of the Commutative Property?

Back

The Commutative Property states that changing the order of the numbers in an addition or multiplication operation does not change the result.

Front

What is the definition of the Associative Property?

Back

The Associative Property states that the way in which numbers are grouped in addition or multiplication does not change the sum or product.

Front

What is the definition of the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac, meaning you can distribute a factor across a sum.

Front

How do you find the slope of a line given its equation in standard form?

Back

To find the slope from the equation Ax + By = C, rearrange it to slope-intercept form (y = mx + b) where m is the slope.

Front

What is the solution to the equation 2x + 3 = 11?

Back

x = 4.
