Answer:
x = - 8 and (- 8, 0 )
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the equation of the axis of symmetry which is also the x- coordinate of the vertex is
x = - 
y = x² + 16x + 64 ← is in standard form, with
a = 1 and b = 16, then
x = - 
= - 8
Equation of axis of symmetry is x = - 8
Substitute x = - 8 into the quadratic and evaluate for y
y = (- 8)² + 16(- 8) + 64 = 64 - 128 + 64 = 0
vertex = (- 8, 0 )
Answer:
-$3800
Step-by-step explanation:
Javier lost $19 on each of his 200 shares, so his total loss was ...
... 200 shares × $19/share = $3800
The portfolio lost $3800 in value on Tuesday.
The ratio of the smaller to the larger is given as 2:4. Another way to write this is as a fraction:
which of course you can see now will reduce to
. That's your ratio.
