Answer:
x=-7

Steps:
-2(x+5)=4
First, multiply everything in the parentheses by -2:
-2x-10=4
Then add ten on the right side to isolate the -2x:
-2x=14
Then divide 14 by -2:
x=-7

The profit (in thousands of dollars) of a company is given by P(x) = -8x2 + 32x + 14.
andre [41]

Answer:

C

Step-by-step explanation:

The profit (in thousands of dollars) of a company is given by the function:

\displaystyle P(x) = -8x^2+32x+14

And we want to find the maximum profit of the company.

Since the function is a quadratic with a negative leading coefficient, the maximum profit will occur at its vertex. Recall that the vertex of a quadratic is given by:

\displaystyle \text{Vertex} = \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)

Find the <em>x-</em>coordinate of the vertex. In this case, <em>a</em> = -8, <em>b</em> = 32, and <em>c</em> = 14. Hence:

\displaystyle x=-\frac{(32)}{2(-8)}=\frac{32}{16}=2

To find the maximum profit, substitute this value back into the function. Hence:

\displaystyle P(2) = -8(2)^2+32(2) + 14 = 46

Therefore, the maximum profit of the company is 46 thousand dollars.

Our answer is C.

Answer:

p = -8.4

Step-by-step explanation:

6(p + 0.4) = 5(p - 1.2) \\ distribute \\ 6p + 2.4 = 5p - 6  \\ 6p - 5p =  - 6 - 2.4 \\ p =  - 8.4

How do you do distributive property
Wittaler [7]
<span>In abstract algebra and formal logic, the distributive property of binary operations generalizes the distributive law from elementary algebra. In propositional logic, distribution refers to two valid rules of replacement. The rules allow one to reformulate conjunctions and disjunctions within logical proofs.</span>
