The answer is C, about 26 mins.
Answer:
Below in bold.
Step-by-step explanation:
x^2 - 2x - 3 = 0
(x - 3)(x + 1) = 0
The zeroes are -1, 3.
Change to vertex form:
= (x - 1)^2 - 1 - 3
= (x - 1)^2 - 4
So the axis of symmetry is x = 1.
The vertex is at (1, -4) and it is a minimum (because the coefficient of x^2 is positive).
Domain is (-∞, ∞)
Range is [-4, ∞).
Increasing when x < 1.
Decreasing when x > 1.
End behaviour x ---- -∞ , y --> ∞
x ----> ∞, y ---> ∞
Answer:
0.15
Step-by-step explanation:
0.15
Answer:
-6(a + 8) = -6a - 48
4(1 + 9x) = 4 + 36x
6(-5n + 7) = -30n + 42
(9m + 10) * 2 = 18m + 20
(-4 - 3n) * -8 = 32 + 24n
8(-b - 4) = -8b - 32
Solve all with Distributive Property of Equality.
Two numbers that are the same distance from zero on a number line are called opposite numbers.
