Answer:
yes
Step-by-step explanation:
Answer:
-5
Step-by-step explanation:
y intercept occurs when x = 0
f(0) = -4(0)² + 2(0) - 5
f(0) = - 5
Answer:
6 x (3-2) = (6 x 3 ) - ( 6 x 1)
Step-by-step explanation:
multiply them together and find out how to distribute it.
18 - 6
(6 x 3 ) - ( 6 x 1)
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
334 is the answer to the question
