The regular price of a child's entry ticket to a water park is $6 less than that for an adult's. The park offers half off all en

pshichka [43]

Let the price of adult's ticket be $x$
the expression for the child's ticket is $x-6$

The price of adult's ticket during off-peak season is $\frac{1}{2}x$
The price of child's ticket during off-peak season is $\frac{1}{2}(x-6)$

The total cost paid by The Sandlers is $78
The equation is $78= \frac{1}{2}x- \frac{1}{2}(2(x-6))$ = $\frac{1}{2}x+(x-6)$

rearranging to solve the equation
$78= \frac{1}{2}x+x-6$
$78= \frac{3x}{2} -6$
$78+6= \frac{3x}{2}$
$(84)(2)=3x$
$\frac{168}{3} =x$
$x=56$

The price of one adult's ticket is $56 (normal price) and the price of one child's ticket is $50

Which statement is true about the discontinuities of the function f(x)?

Tema [17]

Answer:

There are asymptotes at x = three-halves and x = negative one-third.

Step-by-step explanation:

f(x) = (x + 1)/ (6x^2 - 7x - 3)

= (x + 1)( / (6x^2 + 2x - 9x - 3)

= (x + 1) / (2x(3x + 1) - 3(3x + 1))

= (x + 1) / (2x - 3)(3x + 1)

Now x = 3/2 and x = -1/3 both make te denominator zero so these are both asymptotes.
