The domain of this function is x = all real numbers.

The range of this function is that y ≥ 0.

To find the domain, you need to look for exclusions. The only numbers that you exclude are when you can't divide by 0 or have a negative square root. Since this problem has no square root symbol or fractions, it is all real numbers.

For the range, we need to find the smallest value of y. y can get no smaller in this problem than when x = 0. In that case y also = 0. Because the lead coefficient is positive (4), we know that the graph is increasing. Therefore, we know that y must always be bigger than 0.

Please help with this problem
HACTEHA [7]

Answer:

x = 2

Step-by-step explanation:

Multiply both sides by (x-5) and expand:

(x+4)/(x-5)*(x-5) = -2(x-5)

x+4 = -2x+10

Subtract 4 from both sides:

x+4-4 = -2x+10-4

x = -2x+6

Add 2x to both sides:

x+2x = -2x+6+2x

3x = 6

Divide both sides by 3:

3x/3 = 6/3

x = 2

Answer:

Empirical formula

0.34

0.33

0.33

A^c = event B or event C

Step-by-step explanation:

A = roommate A wins the game

P(A) = (Rock A and Scissors B) + (Scissors A and paper B) + (paper A and rock B)

P(A) = (0.36*0.53) + (0.32*0.25) + (0.32*0.22) = 0.3412

C = game ends in a tie :

P(C) = (RockA and rockB) + (ScissorsA and ScissorsB) + (ScissorsA and ScissorsB)

P(C) = (0.36*0.22) + (0.32*0.53) + (0.32*0.25) = 0.3288

P(B) = 1 - P(A) - P(C)

P(B) = 1 - 0.3412 - 0.3288

P(B) = 0.33

Complement of event A =event B or event C
