Equality Properties

Step-by-step explanation:

Step 1: Define Equation

186 = 6(3n + 7)

Step 2: Solve for n

Divide 6 on both sides: 31 = 3n + 7
Isolate n term: 24 = 3n
Isolate n: 8 = n
Rewrite: n = 8

Step 3: Check

Plug in n into the original equation to verify it's a solution.

Substitute in n: 186 = 6(3(8) + 7)
Multiply: 186 = 6(24 + 7)
Add: 186 = 6(31)
Multiply: 186 = 186

Here we see that 186 does indeed equal 186.

∴ n = 8 is the solution to the equation.

Answer:

(a) $R(x)=-0.02x^2+610x$

(b) $R'(x)=-0.04x+610$

(c)R'(5400)=$394

Step-by-step explanation:

Given that x is the quantity demanded and the speaker's unit price (in dollars) is p where:

p = −0.02x + 610 (0 ≤ x ≤ 20,000)

(a)Revenue function R.

Revenue = Price X Quantity Demanded

Therefore:

R(x)=xp

$=x(-0.02x + 610)\\R(x)=-0.02x^2+610x$

(b)Marginal revenue function R'(x)

If $R(x)=-0.02x^2+610x$

Then, the marginal revenue function

$R'(x)=-0.04x+610$

(c)We want to compute R'(5,400)

$R'(5400)=-0.04(5400)+610\\R'(5400)=394$

From the above, we can infer that the revenue that will be generated on the sales of the 5401st item is $394.

Answer:

C) 1/3

Step-by-step explanation:

First look at equation: 3x+y=1

re-write as y=mx+b

y=-3x+1

so the slope of this equation i s-3

so if a line is perpendicular to the above equation,

its slope will be reciprocal negative which is 1/3
