Answer: x = -1
Step-by-step explanation:
Answer:
x = - 1
Step-by-step explanation:
Given a parabola in standard form , f(x) = ax² + bx +c ( a ≠ 0 )
Then the axis of symmetry is calculated using
x = - ![\frac{b}{2a}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7B2a%7D)
f(x) = x² + 2x - 8 ← is in standard form
with a = 1 and b = 2 , then axis of symmetry is
x = -
= - 1, that is
x = - 1

Answer:
Positive Exponent form:
Expanded Form: 1/(5×5×5×5) Simplified Form: ![\frac{1}{625}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B625%7D)
Answer:
perpendicular
Step-by-step explanation:
You can use 2 1/3 and 1 4/3
11/14-n/4=4/14 subtract 11/14 from both sides...
-n/4=-7/14 multiply both sides by -4
n=28/14
n=2
