The solution of the equation is and
Explanation:
The equations are and
First we shall solve the equation graphically.
The image of the graph is attached below.
This contains the solution to the system of equations.
The equations and
are plotted on the graph.
The intersection of these two equations are the solutions of the system of equations.
Thus, the intersection of the two equations are and
Now, we shall solve the equation algebraically.
Let us solve the equation using substitution method.
Let us substitute in
, we get,
Adding both sides by 2x, we have,
Adding both sides by 2, we get,
Dividing both sides by 3,
Thus, the value of x is 3.
Substituting in
, we get,
Thus, the value of y is 1.
Hence, The solution of the equation is and
Answer:
y = 14.4x - 18.4

Answer:
Explanation given below.
Step-by-step explanation:
The first step is to put the parabola in the form , which is the <em>standard form of a parabola</em>
<em />
<u>Note:</u> a is the coefficient before x^2 term, b is the coefficient before x term, and c is the independent constant term
The axis of symmetry divides the parabola symmetrically. The axis of symmetry has the equation
Where <em><u>a and b are the respective values shown above</u></em>
<em><u /></em>
So, that is how you get the axis of symmetry of any parabola.
