How do you find the axis of symmetry?
The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .

7/10
The value of n in the equation -(2n + 4) + 6 = -9 + 4(2n + 1) is 7/10.
Which type’s of equation can have infinite solutions?
linear equations
A system of linear equations has infinite solutions when the graphs are the exact same line.
What is a basic math test?
ACCUPLACER ARITHMETIC TEST This test measures your ability to perform basic arithmetic operations and to solve problems that involve fundamental arithmetic concepts. Operations with decimals and percents: Topics include addition, subtraction, multiplication, and division with decimals.
How do you find the vertex and axis of symmetry?
The Vertex Form of a quadratic function is given by: f(x)=a(x−h)2+k , where (h,k) is the Vertex of the parabola. x=h is the axis of symmetry.
What is the axis of symmetry example?
The two sides of a graph on either side of the axis of symmetry look like mirror images of each other. Example: This is a graph of the parabola y = x2 – 4x + 2 together with its axis of symmetry x = 2. The axis of symmetry is the red vertical line.
What is a correct first step in solving the inequality 4 3 5x ≥ 6x 9?
The correct first step in solving the inequality -4(3 – 5x) ≥ -6x + 9 is -12 + 20x ≥ -6x + 9.
What is the final step in solving the inequality 2/5 4x 6x 4?
x < 3
The final step in solving the inequality -2 (5 – 4x) < 6x – 4 is x < 3.
What is an infinite solution?
It is possible to have more than solution in other types of equations that are not linear, but it is also possible to have no solutions or infinite solutions. No solution would mean that there is no answer to the equation. Infinite solutions would mean that any value for the variable would make the equation true.
Are infinite solutions consistent?
A system of two linear equations can have one solution, an infinite number of solutions, or no solution. If a system has at least one solution, it is said to be consistent . If a consistent system has exactly one solution, it is independent . If a consistent system has an infinite number of solutions, it is dependent .
