Answer:
n=22
Step-by-step explanation:
20-9=11
0.5 x n =11
11/0.5=22
n=22
Answer:
(A)
Step-by-step explanation:
M=-2
therefore
x¹=3, y¹=-12, x²=6 y²=k
M=(y²-y¹)/(x²-x¹)
-2=(k+12)/(6-3)
-2×3=k+12
-6=k+12
k=-18
Answer:
a. y = {x+1, x≤2; x+2, x>2}
Step-by-step explanation:
The open circle at (2, 4) means the function is not defined as y=x+2 at that point. Only one answer selection correctly uses the inequality symbol > for that part of the function definition.
___
Comment on the other answer choices.
One selection (b) uses the region definitions x < 2 and x ≥ 2. That would put the open circle at (2, 3) and the filled circle at (2, 4)—not a match with the graph. The other function definitions (c, and d) have the relation defined as two different values at x=2. Such a relation is not a function.
Answer:
It is b
Step-by-step explanation:
because 1.1 is a 1% increase from 1$
Answer:
1
Step-by-step explanation:
f(x) =1
there is the equation now what you do is put a 1 in front of the x
than you figure it out what to do next
