latavia purchased adult and child tickets for the fall festival. tickets cost $14.88 for each adult and $8.88 for each child. let x represent the number of adult tickets purchased and y represent the number of child tickets purchased. write an expression to represent the total cost of the tickets latavia purchased.

x = adult tickets

y = child tickets

14.88 for adults

8.88 for children

14.88x + 8.88y = total for x amount of adult tickets purchased and y amounts of child tickets purchased.

Ans: 14.88x + 8.88y

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
