Answer:
Step-by-step explanation: Substitute x-c for y in the ellipese equation. Then solve the resulting equation for x, with c as a remining unknown.
Pick the vaue of c that results in one value for x. That will correspond to the tangent-line situation.
hopefully this is right
Answer:
the number of adult tickets sold is
x = 89
and , the number of student tickets sold is y = 178
Step-by-step explanation:
Let the number of adult tickets sold be x and number of student tickets sold be y !
<em><u>Given</u></em><em><u>,</u></em><em><u> </u></em><em><u>:</u></em><em><u>-</u></em><em><u> </u></em> Total 267 tickets were sold
i.e, x + y = 267
x = 267 - y .... ( i )
Also, The number of student tickets sold was two times the number of adult tickets sold.
i.e, y = 2x ...... ( ii )
putting value of x from ( i ) in ( ii )
y = 2 ( 267 - y )
y = 534 - 2y
3y = 534
y = 534/3
y = 178
also, x = 267 - y
x = 267 - 178
x = 89
So, the number of adult tickets sold is
x = 89
and , the number of student tickets sold is y = 178
