Answer:
Why would you ask this in the math area?
Step-by-step explanation:
In set a, every element in the domain has only 1 image in the range. This is called a one-to-one correspondence.
However in set b, there is a many-to-one correspondence as more than 1 element in the domain has the same image.
33 ÷ 3/4 = 33 × 4/3 = 44. The answer is solved by using this equation
If you flipped the picture, it would be 60 degrees. But since its not flipped, it could possibly be 120 degrees since all sides are equal as the sides are parallel to each other.
Hope this helps.
Answer:
Step-by-step explanation:
Let b represent the number of black
ink pens that John wants to buy.
Let r represent the number of red
ink pens that John wants to buy.
John wishes to buy 20 pens. This would be expressed as
b + r = 20
The store sells black ink pens for $5 and red ink pens for $4. John doesn’t wish to spend more than $92. The inequality to show this information would be expressed as
5b + 4r ≤ 92
