Answer:
x = 3
Step-by-step explanation:
given a parabola in standard form : y = ax² + bx + c : a ≠ 0
Then the equation of the axis of symmetry is
x = - 
y = x² - 6x + 
is in standard form
with a = 1 and b = - 6, hence
x = - 
= 3
equation of axis of symmetry is x = 3

Answer:
225,623 miles (363,104 kilometers).
Step-by-step explanation:
Answer:
x=5, y=8. (5, 8).
Step-by-step explanation:
3x+5y=55
5x+4y=57
---------------
5(3x+5y)=5(55)
-3(5x+4y)=-3(57)
-------------------------
15x+25y=275
-15x-12y=-171
---------------------
13y=104
y=104/13
y=8
3x+5(8)=55
3x+40=55
3x=55-40
3x=15
x=15/3
x=5
