The axis of symmetry in form
y=ax^2+bx+c is -b/2a
so
y=x^2-5x+4
y=1x^2-5x+4
-b/2a=-(-5)/(2*1)=5/2
the axis of symmetry is x=5/2
Answer:
The answer will be -5
You are welcome:)
Step-by-step explanation:
So remember that the <u>degree of the polynomial will indicate how many solutions there are, real or complex.</u> Since the degree of the polynomial is 2, this means that there is a maximum of 2 real solutions in this equation.
Next, we are going to apply the difference of squares rule to this polynomial, which is
. In this case:

Now, we are going to apply the Zero Product Property, which states that if a × b = 0, this means that either a or b = 0 or a and b = 0. In this case, a = x + 3 and b = x - 3. Solve each as such:

<u>In short, there are 2 real solutions: x = 3 and x = -3.</u>

The length of the measure of YZ is 80cm
<h3>Perpendicular lines</h3>
Perpendicular lines are lines that are at angle 90 degrees to each other. From the given diagram;
WX = 82cm
Required
Length. of YZ
Using the pythagoras theorem
YV = VZ = √41²-9²
YV = VZ = √1600
YV = VZ = 40
Since YZ = YV + VZ
YZ = 40cm + 40cm
YZ= 80cm
Hence the length of the measure of YZ is 80cm
