Answer:
17/5
Step-by-step explanation:
3 x 5
15+2
17/5
The formula for the axis of symmetry (AOS) is -b/2a.
The 'a' and 'b' values can be derived from examining the standard form of the quadratic,
ax^2+bx+c
In this scenario,
a=5
b=40
Now plug in the values.
-b/2a
-40/2(5)
-40/10
-4
Remember that "-4" is not your answer. Since the AOS is a vertical line of symmetry of any even degree polynomial, your answer would be<u> </u><u>x = - 4
