Answer:
see below
Step-by-step explanation:
f(x) = –(x + 6)(x + 2)
The function is increasing until it reaches the vertex, so it will increase until x=-4. The function will decrease after the vertex, so after x = -4
increasing: -∞ < x < -4
decreasing : -4 < x < ∞
Answer:
16.25$
Step-by-step explanation:
4.25 times 3 = 12.75
vase- 3.50
12.75 + 3.50 = 16.25$
with 3.25$ left.
Answer:
-21, -16, 4, 9
Step-by-step explanation:
-3: f(-3) = 5(-3)-6 = -15-6 = -21
-2: f(-2) = 5(-2)-6 = -10-6 = -16
2: f(2) = 5(2)-6 = 10 - 6 = 4
3: f(3) = 5(3)-6 = 15 - 6 = 9
Answer:
D = 51, other = 30
Step-by-step explanation:
d = | 5 1 |
|-1 10|
D = (5 x 10) - ( 1 x -1) = 50 + 1 = 51
| 2 4|
|-3 9|
(2 x 9) - (4 x -3) = 18 + 12 = 30
Estimate: 4x980= 3920
Actual Product: 3916
