Answer:
Axis of symmetry:
Vertex:
Step-by-step explanation:
The given quadratic equation is
By comparing to the general quadratic function;
We have a=4,b=5,c=-1
The equation of the axis of symmetry is given by the formula;
We got this formula by completing the square on the general quadratic function.
We substitute a=4 and b=5 to obtain;
is the axis of symmetry.
To find the y-value of the vertex, we put into the function to obtain;

im going to assume tomorrow means Two more.....
brilliant.
lets do opposite calculations to both sides. what is the opposite of 2? negative 2. so lets subtract 2 from both sides.
we get
ok so now we have 4 times x. what is the opposite of this? 4 DIVIDED BY x.
ok now lets do the same to the other side. what is negative 20 divided by 4?
Possible answers include what is above
I graphed these vertices myself in the attached photo, and it turned out to be a rectangle; With the thought that you perhaps made a typo and meant rectangle instead of polygon I continued on and found the perimeter of the rectangle.
The formula for finding the perimeter of a rectangle is P = 2(l+w).
I counted the units of the long side (K & J) to get the length, which is 7.
Next, I counted the units between J & H to find the width which is 4. Now we're ready to use the formula.
First I will add the length plus the width, 7 + 4 = 11.
Then I will multiply 2 x 11 to get a product of 22.
P = 22. :D
