At the afternoon matinee movie, 3 adult tickets and 5 child tickets cost $46, and 6 adult tickets and 3 child tickets cost $57. Which two equations can be used to determine the price of each ticket? Let x represent the cost of an adult ticket and y represent the cost of a child ticket.

A. 3x + 5y = 46
6x +y = 52
B. 3x + 6y = 46
5x + 5y = 57
C. 3x + 5y = 46
6x + 3y = 57
D. 3x + 6y = 63
5x + 3y = 40

C

Step-by-step explanation:

3x + 5y = 46

6x + 3y = 57

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
