PLEASE I NEED HELP At a movie theater, the price of 2 adult tickets and 4 child tickets is $48. The price of 5 adult tickets and 2 child tickets is $64. Let x be the cost of an adult ticket and let y be the cost of a child ticket. Write and solve a system of equations to find the ticket price for one adult and for one child.

2x+4y=48

5x+2y=64

x= 10

y=7

(10, 7)

Step-by-step explanation:

5(2x+4y=48)

-2(5x+2y=64)

10x+20y=240

-10x-4y= -128

16y=112

__. ___

16. 16

y=7

2x+4(7)=48

2x+28=48

-28 -28

2x=20

__. __

2. 2

x=10

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho
