Answer:
Step-by-step explanation:
Answer:
2x + 4y =8
substitute 0 for x
2 (0) + 4y = 8
0 +4y = 8
subtract 0 from both sides
-0 +4y =8 - 0
4y = 8
Divide both sides by 4
Y = 2
Step-by-step explanation:
(x − 8)(y − 4) = 50, so y = 4 + 50
x−8
. Then
A(x) = x
4 + 50
x − 8
x > 8.
A
0
(x) = 4 −
400
(x − 8)2
, so A
0
(x) = 0 gives x = 18.
A
00(x) = 800
(x − 8)3
> 0
so the function is concave up, so x = 18 is the absolute minimum. When x = 18, y = 9.
Answer:
3
Step-by-step explanation:
The given data shows that only 1 row was in use. We also know that Mr. Torres is an adult. So for the ease, lets use A for Adult and S for student.
The seating must fulfill the requirements that 4 students must be between adults such that it would be "A-S-S-S-S-A"
On a row of 11 seats, this should be the searing arrangements.
A-S-S-S-S-A-S-S-S-S-A ( for 1 row).
Mr. Torres could be any A .
