Answer:
c=|x-7|
Step-by-step explanation:
Answer with Step-by-step explanation:
We are given that an equivalence relation P on Z as
Let 
if and only if
such that x-y=2k.
We have to show that how the reflexive property and symmetric property of an equivalence relations hold for P on Z.
We know that reflexive property
a is related to a by given relations.
If xPax then we get

Where k=0 and 0 belongs to integers.
Hence, the relation satisfied reflexive property.
Symmetric property :If a is related to b then b is related to b.
If x and y is related by the relation
where k is any integer

k belongs to integers.
Hence, relation satisfied symmetric property.

The actual cost to rent the boat per hour is $12.75 when you multiply all the other hours by 12.75 it equals the correct amount except for (D) 5 ×12.75 = 63.75
Your answer is 10 for m<5
Answer:
-28(2z - 1)
Step-by-step explanation:
Looking at the coefficients -56 and 28 in -56z + 28, we see that -28 is common to both and can be factored out:
-56z + 28 = -28(2z - 1).
