Answer:

x = -1

Step-by-step explanation:

Step 1: Distribute

-5(x + 2) = -(-5x + 1) - x

-5x - 10 = 5x - 1 - x

-5x - 10 = 4x - 1

Step 2: Solve for x

-5x - 10 + 5x = 4x - 1 + 5x

-10 + 1 = 9x - 1 + 1

-9 / 9 = 9x / 9

-1 = x

Answer: x = -1

Find a cubic function f(x) = ax^3 + bx^2 + cx + d that has a local maximum value of 3 at x = −3 and a local minimum value of 0 a

Ahat [919]

Answer:

f(x) = (3x³ + 9x² - 27x + 15)/32

Step-by-step explanation:

f'(x) = 3ax² + 2bx + c

Maximum or minimum: f'(x) = 0

Maximum: f'(-3) = 0 and f(-3) = 3

Minimum: f'(1) = 0 and f(1) = 0

f'(-3) = 0 leads 27a - 6b + c = 0 (1)

f'(1) = 0 leads 3a + 2b + c = 0 (2)

f(-3) = 3 leads -27a + 9b -3c + d = 3 (3)

f(1) = 0 leads a + b + c + d = 0 (4)

(1) - (2): 24a - 8b = 0, or 3a - b = 0, b = 3a

(3) - (4) -28a + 8b - 4c = 3 (5)

(1) * 4 + (5): 80a - 16b = 3,

use b = 3a, get 80a - 16*3a = 3, 32a = 3, a = 3/32, b = 3a = 9/32

From (2): c = -3a - 2b = -9/32 - 18/32 = -27/32

From (4): d = -a - b - c = -3/32 - 9/32 + 27/32 = 15/32

f(x) = (3x³ + 9x² - 27x + 15)/32

Write 6^8 • 6^7 as a single power

taurus [48]

<h3>Write 6^8 • 6^7 as a single power:</h3>

$6^8 \times 6^7 = 6^{15}$

Solution:

Given that,

We have to write 6^8 • 6^7 as a single power

Given is:

$6^8 \times 6^7$

Use the following law of exponent

$a^m \times a^n = a^{m+n}$

When, the base is same, powers gets added

Therefore,

$6^8 \times 6^7 = 6^{8+7}\\\\6^8 \times 6^7 = 6^{15}$

Thus the given is written as a single power
