The value is -3.

What property is illustrated by the equation 4+(3+2)=(4+3)+2?

Associative property.

True or False: An integer is also a counting number.

False.

Evaluate 3x+2y²z when x=-3, y=2, and z=-3.

The result is -33.

What is the simplified form of (2x³+7x²-4x+2)-(5x²-3x+1)?

2x³ + 2x² - x + 1.

Simplify (x-4)(2x+3). What is the result?

2x² - 5x - 12.

What is the result of simplifying 27x³y⁷ - 12x²y³z³ over 9x³y³?

3x²y⁴.

Is 2x² + 19x - 5 a quadratic equation?

No, it is classified as a quadratic.

Solve the equation: 2x-(3+6x)=3(2x-8)-20.

The solution is x = -3.

Andrew is x and Jack is 5x - 2.

How do you factor the expression 12x³y³ + 18x²y³?

The factored form is 6x²y³(2xy + 3).

What is the factored form of 64x² - 81y²?

The expression factors to (8x - 9y)(8x + 9y).

What are the solutions to the compound inequality -7≤ 10x-2<28?

x is in the interval [-3, 2.5).

Does the graph representing the relation: {(2,-1),(5,4),(3,3),(2,1)} suggest it is a function?

No, it is not a function.

What is the domain and range of the given graph?

Domain: [4, 2]; Range: [-3, 1].

What line represents the standard form of the equation 9y=18-3x?

The standard form is x + 3y = 6.

Determine if lines represented by 7x - 2y = -6 and y = 1/2x - 9 are parallel, perpendicular, or neither.

The lines are parallel.

What is the regression equation from the population data?

y = 0.2038x + 10.638.

What indicates the solution to the inequality y >= x + 2 when tested with the point (0,0)?

It is false; thus, shade the opposite side.
