Answer:

(1, - 5)

Step-by-step explanation:

To determine which ordered pair is a solution

Substitute the x value into the right side of the equation and if the value is equal to the y- coordinate of the point then it is a solution.

(1, - 5)

y = - 4(1) - 1 = - 4 - 1 = - 5 ← True

(4, 15)

y = - 4(4) - 1 = - 16 - 1 = - 17 ≠ 15

(2, - 7)

y = - 4(2) - 1 = - 8 - 1 = - 9 ≠ - 7

(- 5, 1)

y = - 4(- 5) - 1 = 20 - 1 = 19 ≠ 1

(1, - 5) is a solution to the equation y = - 4x - 1

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $2,632 was collected on the sale of 1,128 ticket
MAVERICK [17]

Answer:

A = number of adult tickets

S = number of student tickets

1033 = total tickets sold

A + S = 1033

5A = money collected for adult tickets

S = money collected for student tickets

2265 = total money collected

5A + S = 2265

two equations and two unknowns:

5A + S = 2265

A + S = 1033

subtract 2nd equation from 1st and solve for A:

4A = 1232

A = 308

Plug in value for A in 1st equation and solve for S:

A + S = 1033

308 + S = 1033

S = 725
