ANSWER
B. 1
EXPLANATION
The given function is
This is a piece-wise defined function.
We want to find f(1)
We substitute x=1 into f(x)=x because, 1 belongs to the interval,
1≤x≤5
f(1)=1
The correct answer is B.
Step-by-step explanation:
Line A : x + y = 2
The most likely equation for line B so that the set of equation has no solution is:
x + y = 4
====
x + y = 2
x = 2 - y
2-y + y = 4
0 = 4 - 2
0 ≠ 2
there is no value for x nor y. so, no solution.
It’s B
you want to get the x by itself on one side. so subtract 71 from both sides. 5x>=-85. divide both sides by 5, and x>= -17
Answer:
D. 2,880 feet.
Step-by-step explanation:
You do 775 x 2 + 665 x 2, which equals 2,880 feet.
