Answer:
The axis of symmetry is 
Step-by-step explanation:
we know that
In a vertical parabola, the axis of symmetry is equal to the x-coordinate of the vertex
In this problem we have a vertical parabola open upward
The x-coordinate of the vertex is equal to the midpoint between the zeros of the parabola
so

therefore
The axis of symmetry is 
The expression that gives an angle that is coterminal with 300 is 300-720. Two angles are said to be coterminal if when they are drawn in a standard position, their terminal sides are on the same location. The expression gives an angle of 420 where when it is drawn the terminal sides are on the same location with the 300.

Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 4 is in this form
with y- intercept c = 4 → A
Answer:
<h2>B. 2x + y = 4</h2>
Step-by-step explanation:
Having the system of equations in its simplest form

If

then the system of equations has infinitely many solutions.
If

then the system of equations has no solution.
If

then the system of equations has one solution.
We have the equation

Convert to the standard form Ax + By = C<em>:</em>
<em />
<em> add 2x to both sides</em>
