Answer: n= 0

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8n−6(−5n−3)=18+7n

8n+(−6)(−5n)+(−6)(−3)=18+7n(Distribute)

8n+30n+18=18+7n

(8n+30n)+(18)=7n+18(Combine Like Terms)

38n+18=7n+18

38n+18=7n+18

Step 2: Subtract 7n from both sides.

38n+18−7n=7n+18−7n

31n+18=18

Step 3: Subtract 18 from both sides.

31n+18−18=18−18

31n=0

Step 4: Divide both sides by 31.

31n /31  = 0 /31

n=0

Answer:

n=0

Answer:

See attachment

Step-by-step explanation:

Isolate y in the first inequality:

2x + 4y < -16\\4y < - 16 -2 x\\y < -4 -\frac{1}{2} x\\y < -\frac{x+8}{2} \\

Now, with both x and y inequalities found, graph it.

Determine the graph of the polar equation r=4/(1-1/2cosx(theta))
crimeas [40]

Answer:

  see below

Step-by-step explanation:

We assume you want the graph of ...

  r=\dfrac{4}{1-\frac{1}{2}\cos{(\theta)}}

A graphing calculator or spreadsheet is useful for this.

__

You know cos(θ) = cos(-θ), so the graph is symmetrical about the x-axis. You can evaluate the function at a few points to find the general outline.

  r at 0° = 8

  r at 30° ≈ 7.05

  r at 45° ≈ 6.19

  r at 60° ≈ 5.33

  r at 90° = 4

  r at 120° = 3.2

  r at 135° ≈ 2.96

  r at 150° ≈ 2.79

  r at 180° ≈ 2.67

When rolling fair number cube with numbers 1 through 6 what is the probability of rolling a number less than 3
jenyasd209 [6]

Each face of the cube has an equal \dfrac16 probability of being rolled. There are 2 numbers on the cube less than 3 (1 and 2). The event of rolling a 1 and the event of rolling a 2 are mutually exclusive (you can't roll both faces at once), so

P(1\text{ or }2)=P(1)+P(2)=\dfrac16+\dfrac16=\dfrac13
