A movie theater sells only two types of tickets: adult tickets for $20 each and student tickets for $12 each. One weekend, the t
Yakvenalex [24]

Answer:

adults tickets=1384

kids:616 tickets

1384-616= 768 tickets

Step-by-step explanation:

let x be adult tickets and y kids

x+y=2000 ⇒x=2000-y

20x+12y=35072   solve by substitute for x=2000-y

20(2000-y)+12y=35072

40000-20y+12y=35072

-8y=35072-40000

-8y=-4928

y=-4928/-8

y=616

x=2000-616

x=1384 tickets

check:

20(1384)+12(616)=35072 ( correct)

Y= -2x-21<br> determine the intercepts of the line
puteri [66]

Answer:

The y-intercept is -21. The x-intercept is -10.5 or -\frac{21}{2}.

(0, -21) and (-10.5, 0)

Step-by-step explanation:

To find the y-intercept, you would plug in 0 for x.

y = -2x - 21

y = -2(0) - 21

y = 0 - 21

y = -21

The y-intercept is -21.

To find the x-intercept, you would plug in 0 for y.

y = -2x - 21

0 = -2x - 21

2x = -21

x = -21/2

x = -10.5 or -\frac{21}{2}

The x-intercept is -10.5 or -\frac{21}{2}.
