What is the result of multiplying (x + 3)(x + 2) using the distributive property?

Which property states that a + b = b + a?

• Associative Property

• Distributive Property

• Commutative Property

• Identity Property

What is the Associative Property of addition?

• (a + b) + c = a + (b + c)

• a + b = b + a

• a + 0 = a

• a * (b + c) = (a * b) + (a * c)

What is the Identity property of addition?

• a + 0 = a

• a + 1 = a

• a + a = 0

• a - 0 = a

What is the recursive rule for a geometric sequence?

• a_n = a_(n-1) * r

• a_n = a_(n-1) + r

• a_n = a_(n-1) / r

• a_n = a_(n-1) - r

What is the equation of a line in slope-intercept form?

• y = mx + b

• y = bx + m

• x = my + b

• y = b + mx

What is the equation of a line in point-slope form?

• y - y_1 = m(x - x_1)

• y = mx + b

• x - x_1 = m(y - y_1)

• y = m(x + x_1)

What is the decay formula for exponential growth and decay?

• y = ab^x where a > 0 and 0 < b < 1

• y = ab^x where a > 0 and b > 1

• y = a(1 - r)^x where a > 0 and 0 < r < 1

• y = a(1 + r)^x where a > 0 and r > 0

What is the growth formula for exponential growth and decay?

• y = ab^x where a > 0 and b > 1

• y = a + bx where a > 0 and b > 1

• y = a - bx where a > 0 and b > 1

What is the function of a relation?

• function is a relation in which every domain value is paired with exactly one range value

• function is a relation where one domain value can be paired with multiple range values

• function is a relation that does not involve domain and range values

• function is a relation that only involves numerical values
