Answer:

only Y

Step-by-step explanation:

all the others have for at least 1 value of x more than one different y values defined.

but a function must be clear about the association between an x unit value and the corresponding result.

many different input values can have the same functional result. but there can be only one defined result per input value. otherwise it is not a function.

you cannot say 1+1 = 2 or 3. it is either 2 or 3, but you need to define what. you can't leave it open.

Two people can complete 60% of a task in t hours, where t must satisfy the equation t 10 + t 15 = 0.6. How long will it take for

notsponge [240]

Answer:

0.024h

Step-by-step explanation:

We have the equation:

t 10 + t 15 = 0.6

<=> 25t = 0.6

<=> t = 0.024

It means that, it takes 0.024h for two people to complete 60% of the task

I hope it will find you well.

Mary Hernandez had a policy with a $500 deductible which paid 80% of her covered charges less deductible. She had medical expens

12345 [234]

A.) The insurance company's payment is 80% of the total minus the $500 deductible, so:
(10000 - 500) * .8 = 7600

B.) To find the Copay, you do almost the same thing:
(10000 - 500) * .2 = 1900

C.) Mary's Total Cost: 1900 + 500 = 2400.00
