Answer:
See below.
Step-by-step explanation:
a.
x = cost of adult ticket
y = cost of student ticket
cost of adult ticket is twice the cost of a student ticket
x = 2y
number of adult tickets = 64
number of student tickets = 132
cost of all adult tickets = 64x
cost of all student tickets = 132y
cost of all adult and student tickets combined: 64x + 132y
cost of all adult and student tickets combined: 1040
This gives us the equation:
64x + 132y = 1040
b.
Use substitution to solve the system of equations. Since x = 2y, where you see x in the second equation, substitute it with 2y.
64(2y) + 132y = 1040
128y + 132y = 1040
260y = 1040
y = 1040/260
y = 4
x = 2y = 2(4) = 8
adult ticket: $8
student ticket: $4
Answer:
Line segment because it is part of a line that has two endpoints which are the 0 inch mark and the 12 inches mark.
Answer:
18.25m
Step-by-step explanation:
Subtracting the two Vectors we have
= 3ti - 4ti + t^2j - - t^2j
=- 1ti + 2 t^2j
= The distance between the lines is given by
= Squaroot of ( ( -3)^2 +( 2(3)^2 )^2
= Squaroot of 9 +324
= Squaroot of 333
= 18.25m
