<span>In the function "y=x2-18x" the goal is to find the value of the letter x. We know that y equals x2-18x. First, recognize that x2 is the same thing as 2x. So changing the problem to "y=2x-18x". We can subtract 18x from 2x, which leaves us with -16x. Now the problem looks like this: y=-16x. In order to get x by itself, we will need to do the same thing to both sides of the equation. In this case, we want the answer to be x by itself, or (1x) which is the same thing. We divide both sides of the equation by (-16). We are left with the following: y/-16=x. Basically, in words, x equals y divided by negative 16.</span>
Answer:
a: the players are you and your friend. No, there are no dominant strategies. Recall that a dominant strategy is one that yields a higher payoff regardless of the strategy chosen by the other player. In this game, if your friend plays one side, you will match that side; however, if you match, your friend will then want to change strategies, and you will therefore want to change your strategy in order to receive a higher payoff. No, there is no equilibrium. As discussed in part b, if your friend plays one side, you will match that side; however, ifyou match, your friend will then want to change strategies, and you will therefore want to change your strategy in order to receive a higher payoff

Answer:
A
Step-by-step explanation:
Given 2 secants from a point outside the circle.
Then the product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is
(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)
(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides
x² + 13x + 12 = x² + 9x + 20 ← subtract x² + 9x from both sides
4x + 12 = 20 ( subtract 12 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2 → A
Answer:
Laura is 8
Step-by-step explanation:
let Laura's age now be x then Daniel's age is 2x
4years ago
Laura was x - 4 and Daniel 2x - 4, thus
2x - 4 = 3(x - 4) ← 3 times Laura's age
2x - 4 = 3x - 12 ( subtract 2x from both sides )
- 4 = x - 12 ( add 12 to both sides )
8 = x
Thus Laura is 8 years old
