One mile equals 5,280 feet, therefore you would multiply 12 x 5,280 which is 63360 feet per hour.
9 < = 6 - y
9 - 6 < = -y
3 < = -y
-3 > = y or y < = -3
solutions include : -3,-4,-6
Answer:
Step-by-step explanation:
F(x) = 7 - 5x + 7x²
f(-9) = 7 - 5*(-9) + 7*(-9)²
= 7 + 45 + 7*81
= 7 + 45 + 567
= 619
Answer:
x=0
Step-by-step explanation:

Answer:
x + y ≤
3x + 5y ≥ 1100
Step-by-step explanation:
Given:
Seating capacity of theater = 250
Cost of each child ticket = $3
Cost of each adult ticket = $5
Cost per performance = $1100 at least
Find:
System of inequalities
Computation:
Let;
x = Number of children's tickets
y = Number of adult tickets
So
x + y ≤
3x + 5y ≥ 1100
