What is the solution to the equation @@2(x+9)=4(x+7)+2@@?

• x = -6

• x = -4

• x = 2

• x = 0

How can you verify the solution of an equation?

• By substituting it back into the original equation to see if both sides are equal.

• By solving the equation again from scratch.

• By checking the solution against a different equation.

• By graphing the equation and seeing if the point lies on the curve.

What is the factored form of the expression @@m^2-25@@?

• @@(m-5)(m+5)@@

• @@(m-10)(m+10)@@

• @@(m-1)(m+25)@@

• @@(m-5)(m-5)@@

What is the angle of elevation?

• The angle formed by a horizontal line and the line of sight to an object above the horizontal line.

• The angle formed by a vertical line and the line of sight to an object below the horizontal line.

• The angle between two horizontal lines in the same plane.

• The angle formed by the intersection of two vertical lines.

What does it mean for an expression to be equivalent?

• Two expressions are equivalent if they have the same value for all values of the variable.

• Two expressions are equivalent if they are written in the same way.

• Two expressions are equivalent if they contain the same number of terms.

• Two expressions are equivalent if they can be simplified to the same expression.

How do you solve a quadratic equation?

• By using the quadratic formula

• By graphing the equation

• By taking the square root of both sides

• By multiplying both sides by zero

What is the difference between a maximum and minimum in a quadratic function?

• A maximum is the highest point on the graph, while a minimum is the lowest point. For the function @@y=3x^2-12x+9@@, it has a minimum at @@ (2, -3)@@.

• A maximum is the lowest point on the graph, while a minimum is the highest point.

• A maximum occurs when the function is increasing, while a minimum occurs when the function is decreasing.

• A maximum and minimum are both points where the function crosses the x-axis.

What is the sine ratio in a right triangle?

• The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse.

• The sine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse.

• The sine of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

• The sine of an angle is the ratio of the length of the hypotenuse to the length of the adjacent side.

How do you find the x-intercepts of the function @@y=3x^2-12x+9@@?

• Set @@y=0@@ and solve for @@x@@. The x-intercepts are @@ (1, 0) @@ and @@ (3, 0) @@.

• Set @@y=0@@ and solve for @@x@@. The x-intercepts are @@ (0, 0) @@ and @@ (4, 0) @@.

• Set @@y=0@@ and solve for @@x@@. The x-intercepts are @@ (2, 0) @@ and @@ (5, 0) @@.

• Set @@y=0@@ and solve for @@x@@. The x-intercepts are @@ (1, 0) @@ and @@ (2, 0) @@.

What is the relationship between the coefficients of a quadratic function and its graph?

• The coefficients determine the shape and position of the parabola.

• The coefficients only affect the position of the vertex.

• The coefficients have no effect on the graph of the function.

• The coefficients determine the color of the graph.
