2c - 5 < -21 - 2c |add 5 to both sides
2c < -16 - 2c |add 2c to both sides
4c < -16 |divide both sides by 4
c < -4
The answer is C - Money Market Account
Answer:
4| 7
5| 2 7 8 8
6| 1 6 6 8 8
7| 0 2 2 3 3 5 6 7
8| 4 4 4 5 6 6 7 9
9| 0 1 1 2 3 7
And with the notation 4|7 represent 47
Step-by-step explanation:
For this case we have the following dataset given:
58 52 68 86 72 66 97 89 84 91 91 92 66 68 87 86 73 61 70 75 72 73 85 84 90 57 77 76 84 93 58 47
And if we order the dataset in increasing way we got:
47 52 57 58 58 61 66 66 68 68 70 72 72 73 73 75 76 77 84 84 84 85 86 86 87 89 90 91 91 92 93 97
And if we create the stem plot we got:
4| 7
5| 2 7 8 8
6| 1 6 6 8 8
7| 0 2 2 3 3 5 6 7
8| 4 4 4 5 6 6 7 9
9| 0 1 1 2 3 7
And with the notation 4|7 represent 47
<u>Vertex</u>
y = -(x + 3)² + 1
y = -(x + 3)(x + 3) + 1
y = -(x² + 3x + 3x + 9) + 1
y = -(x² + 6x + 9) + 1
y = -x² - 6x - 9 + 1
y = -x² - 6x - 8
-x² - 6x - 8 = 0
x = <u>-(-6) +/- √((-6)² - 4(-1)(-8))</u>
2(-1)
x = <u>6 +/- √(36 - 32)</u>
-2
x = <u>6 +/- √(4)
</u> -2<u>
</u>x = <u>6 +/- 2
</u> -2
x = <u>6 + 2</u> x = <u>6 - 2</u>
-2 -2
x = <u>8</u> x = <u>4</u>
-2 -2
x = -4 x = -2
y = -x² - 6x - 8
y = -(-4)² - 6(-4) - 8
y = -(16) + 24 - 8
y = -16 + 24 - 8
y = 8 - 8
y = 0
(x, y) = (-4, 0)
or
y = -x² - 6x - 8
y = -(-2)² - 6(-2) - 8
y = -(4) + 12 - 8
y = -4 + 12 - 8
y = 8 - 8
y = 0
(x, y) = (-2, 0)
<u>Axis of Symmetry</u>
The axis of symmetry is equal to -3.

C- Evolutionarily they have adapted to their surroundings (its lighter on the beach compared to inland)
hope the helped!
