This depends on the price of how much the tickets cost in total so if the 10 tickets cost $10 dollars then the unit price would be $1

Step-by-step explanation:

You need to divide the total number by the number 10 and then that would be your unit price.

Which inequality represents all values of x for which the product below is<br> defined?<br> 20 pts
timama [110]

Step-by-step explanation:

√a is defined only when a >= 0.

Therefore for √4x * √(x + 2) to be defined, both 4x and x + 2 must be non-negative.

When 4x >= 0, x >= 0.

When x + 2 >= 0, x >= -2.

x >= 0 and x >= -2, therefore we have x >= 0. (D)

Show work and solve for √ ( 5 x − 9 ) − 1 = x.
Mandarinka [93]

sqrt (5x - 9) - 1 = x

sqrt(5x - 9) = x + 1

Square both sides:_

5x - 9 = x^2 + 2x + 1

x^2 - 3x + 10 = 0

(x - 5)(x + 2) = 0

x = 5 or -2.

Lets look for for any extraneous solutions:-

x = 5 ;  sqrt (5*5-9) - 1 = sqrt16 - 1 =  3  and  x = 3  (right hand side of equation)

so x = 5 is a solution

x = -2:  sqrt(5*-2 - 9) - 1 =  sqrt (-19) - 1  and x = -2  so this is extraneous

Answer:- One solution x = 5
