Answer:
a, b, d
Step-by-step explanation:
For the inequality x ≥ -3 . . .
a(0, -2) . . . 0 ≥ -3, true
b(-3, 4) . . . -3 ≥ -3, true
c(-4, 2) . . . -4 ≥ -3, FALSE
d(5, -5) . . . 5 ≥ -3, true
Points a, b, d satisfy the inequality.
the vertex is (1,-1)
y = −3x^2 + 6x − 4
the vertex is at
h= -b/2a where ax^2 +bx+c
h= -6/2(-3)
h= -6/-6
h=1
substitute this in to find the y value
y = -3(1)^2 +6(1)-4
y = -3+6-4
y = -1
Answer: 16%
$25 - $21 = $4
Percentage = 100[discount / (original price)] % = 100($4 / $25) % = 16%
the distance is 3
