Let x represent lower level tickets that cost $77
Let y represent upper level tickets that cost $99
Cost equation: 77x + 99y = 247,071
Tickets equation: x + y = 2615
Using the elimination method, multiply the second equation by -77:
77x + 99y = 247,071
-77x - 77y = -201,355
--> 22y = 45,716
--> y = 2,078
Now plug "y" into either equation and solve for "x". I chose the Tickets equation. x + y = 2615 → x = 2615 - y → x = 2615 - 2078 → x = 537
Answer: lower level = 537 tickets, upper level = 2078 tickets.
Answer:
None of the above, f(5) + g(-3) = 19.
Step-by-step explanation:
Given f(x)=2x+4 and g(x)=x2−4, determine the value of (5) + (−3). Assume that is supposed to be f(5) + g(-3).
f(5) + g(-3) = 2×5 + 4 + (-3)^2 - 4
= 10 + 4 - 4 + (-1)^2(3)^2
= 19
Answer:
3x - 2y = -32
Step-by-step explanation:
Ax + By = C
2y = 3x + 32
-3x -3x
-3x + 2y = 32 (the leading coefficient needs to be positive)
-1(-3x + 2y = 32)
3x - 2y = -32
Hope this helps!
