Given that y is the number of people in the line after 5 am and there are already 3 hours that have passed for 8 am, we substitute 3 to the equation to find the answer.
y = (-5.131)(3²) + 31.821(3) - 3.333
Simplifying,
y = 45.951
Thus, the answer is letter C. 46.
Answer:
x = 11
Step-by-step explanation:
16x - 8 = 14x + 14
add 8 to both sides
16x = 14x + 22
subtract 14x from both sides
2x = 22
divide both sides by 2
x = 11
Answer:
369.42
Step-by-step explanation:
A=a+b
2h=31+25.4
2·13.1≈369.42
Answer:
C. (x-3)^2
Step-by-step explanation:
x^2-6x+9 is a perfect square meaning that (a-b)^2=a^2-2ab+b^2
x^2-6x+9 --> a=x, b=3
so (a-b)^2=(x-3)^2
