Answer:
(x - 3)² - 16 = 0
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Subtract 7 from both sides
x² - 6x + 7 = 0 ← in standard form
with a = 1, b = - 6
Given a quadratic in standard form then the x- coordinate of the vertex is
= -
= -
= 3
Substitute x = 3 into the equation for y
y = 3² - 6(3) - 7 = 9 - 18 - 7 = - 16 ⇒ (h, k) = (3, - 16)
y = (x - 3)² - 16 = 0
Answer:
c
Step-by-step explanation:
(5/6 + 2/3) - (3/4 + 1/12
= 9/6 - 10/12
= 18/12 - 10/12
= 8/12
= SIMPLIFY: 2/3
Hope this helps!!
Answer:
Step-by-step explanation:
Answer:
B: -a > -b
Step-by-step explanation:
a = 1, -a = -1
b = 3, -a = -3
-1 > -3
Therefore, -a > -b
