Solve for x over the real numbers:2 x^2 - 3 x - 2 = x + 4
Subtract x + 4 from both sides:2 x^2 - 4 x - 6 = 0
The left hand side factors into a product with three terms:2 (x - 3) (x + 1) = 0
Divide both sides by 2:(x - 3) (x + 1) = 0
Split into two equations:x - 3 = 0 or x + 1 = 0
Add 3 to both sides:x = 3 or x + 1 = 0
Subtract 1 from both sides:Answer: x = 3 or x = -1
Step-by-step explanation:
6x + 9 = 12
6x = 12 - 9
6x = 3
x = 3/6 = 1/2

Is there a picture of the graphs...?
Step-by-step explanation:
Anyways, the answer should be y= 3/2x +4
If you show me the graphs I could possibly help you find which one is correct.

Step-by-step explanation:
Let's call:
n: the number of adults interviewed
t: number of adults who watch tennis
d: number of adults who practice some sport
x: number of adults who watch tennis and do not practice a sport
The probability that a randomly chosen adult watches tennis and does not play any sports is calculated as follows:
- We calculate the probability that a selected adult will see tennis.
P(t) = 92/140 = 0.657
- We calculate the probability that an adult plays a sport:
P(d) = 81/140 = 0.5786
- We calculate the probability that an adult will see tennis and play some sport (See diagram attached)
P (t ∩ d) = 0.657 (0.5786) = 0.3802
Finally the probability that an adult who sees tennis does not play any sport is:
P(x) = P(t) - P(t ∩ d) = 0.657 - 0.3802
P(x) = 0.277
