Let x_1 , x_2 be the roots of the equation 3x^2-5x-7. By the Viet theorem you have that \left \{ {{x_1+x_2=- \frac{5}{3} } \atop {x_1x_2= \frac{-7}{3} }} \right..

For the equation x^2+bx+c = 0 you'll have that c=(x_1+2)(x_2+2)=x_1x_2+2(x_1+x_2)+4=\frac{-7}{3}+2\cdot(- \frac{5}{3} )+4
That is \frac{-7}{3}- \frac{10}{3} +4=- \frac{5}{3}.

Answer: - \frac{5}{3}

The table below shows the numbers of tickets sold at a movie theater on Friday.
sleet_krkn [62]

Answer:

Number of Adult's tickets sold on Saturday = 3,356

Number of Children's tickets sold on Saturday = 2, 928

Total number of tickets sold over these two days is 8,938.

Step-by-step explanation:

Here, the number of tickets sold on FRIDAY:

Adult Ticket sold = 1,678

Children's Tickets sold = 976

So, the total number of tickets sold on Friday  

= Sum of ( Adult + Children's ) tickets  = 1,678  + 976 = 2,654 ....  (1)

The number of tickets sold on SATURDAY:

Adult Ticket sold =   2 times as many as the number of adult tickets sold

on Friday

=  1,678 x 2  = 3,356

Children's Tickets sold = 3 times as many as the number of children's

tickets sold on Friday.

=  976  x 3 = 2, 928

So, the total number of tickets sold on Saturday  

= Sum of ( Adult + Children's ) tickets  = 3,356 + 2,928 = 6, 284 ....  (2)

Now, the total number of tickets booked in these two days :

Sum of tickets booked on (Friday + Saturday)

= 2,654 +  6, 284  =   8,938

Hence, total number of tickets sold over these two days is 8,938.
