For one to one function each element in the domain is mapped on to an one and only one element in the co-domain.
The could be some elements in the co-domain that are not being used.
For a function to be one to one, then for
if and only if
For an onto function all the elements in the co-domain must be used up.
In order words, the
The condition is
Meaning each
<span>For the first part we have 6 people and therefore must do 6 times 27 which gives us 162.
For our second portion we have 4 people so we do 4 times 23 which give us 92.
So the sum of the ages from the last 2 people must obviously be 162 minus 92 which gives us 70.
Since the sum of the ages of the last three must be 3 times 34 > 92, the age of the 4th person has to be 92 minus 70 > This gives us 22 as our final answer.. </span>
Answer:
Are you sure it is 1830?
Or is it a typo and might 18?

Answer:
cherry street is 85 yards, while orange dr. and peach ave. is 113 yards, meaning that cherry st. is 28 yards faster
Step-by-step explanation:
85 x 85) - (77 - 77) = 1296
square root of 1296 is 36
77 + 36 = 113
113 - 85 = 28
this means that cherry st. is 28 yds faster

A.)Hey, there! If you look at the table below, you can see that the output is always 6 more than the input. This means that the rule for this is . The first one, for example, would be (4) + 6 = 10 because you are substituting for the value of x. The second would be (5) + 6 = 11 and so on.
B.) This problem is designed to trip you up. Notice how it says to write an equation for the cost of the number of razors you buy? It doesn't say anything about finding the monthly fee, which means that the number of razors (x) will be our variable. The equation will look like this: , because even if you don't buy any razors, you still have to pay the $12 monthly fee.
Hope this was helpful. :)
