Answer:
The given relation is a function.
Step-by-step explanation:
A relation is given.
It is required to determine whether the given relation is a function.
To determine whether the given function is a relation, identify the domain and range and then check whether the given relation is a function.
Step 1 of 1
The given relation is {(a, b),(c, d),(e, d)}.
The set of the first components of each ordered pair is called the domain.
From the relation, the domain is {a, c, e}.
The set of the second components of each ordered the range.
From the relation, the range is {b, d, d}.
The given relation is a function. But it is not a one-to-one function.
Answer:
n= 100
Step-by-step explanation:
Product is the answer when two numbers are multiplied together. So, n×-6=600.
100×-6=-600
Answer:
x>-7
Step-by-step explanation:
2x+3>-11
subtract 3 on both sides
2x>-14
divide by 2 on both sides
x>-7
Note: When dividing or multiplying by a negative number, be sure to flip the inequality symbol!
Answer: x(0.55)
Step-by-step explanation:
Because 45% of the price is being taking, off we are still paying for 55% of the market price, because 100%-45%=55%.
55/100=0.55
So the sale price is x(0.55)
