Graph the relation. Is the relation a function? Why or why not?
{(-1, 9), (0, -1), (-1, 4), (4, 9)}

No; a domain value has two range values.

Yes; there is only one domain value for each range value.

Yes; there is only one range value for each domain value.

No; a range value has two domain values.

Answers

Answer 1

Answer:

No; a domain value has two range values.

Step-by-step explanation:

Because domain value is the x value and range value is the y value. If the x value repeats then it is not a function.

Answer 2

Answer: I think the answer is letter A . "No; a domain value has two range values".

The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6.... The range of the function is the set of all values that f takes.

Since  

x  =  − 1

produces  

y =  9

and  

y =  4 , the relation  

( − 1 , 9 ) ,     ( 0 ,  − 1 ) ,     ( − 1 ,  4 ) ,     ( 4 ,  9 )

is not a function.

The relation is not a function.

Graph.

{ ( − 1 ,  9 ) ,     ( 0 ,  − 1 ) ,     ( − 1 ,  4 ) ,     ( 4 ,  9 ) }

Step-by-step explanation: It's either A or D

what is domain value

The value of a domain name is the price any person/entity/organization has to pay in order to purchase a name for their website. The costs can range from a one-digit number to 6- or 7-digit numbers, depending on the valuation factors. Your domain could be the name of the next big start-up or brand.... The domain of a function f(x) is the set of all values for which the function is defined

The domain is the set of all the values of  

x

. The range is the set of all the values of  

y

.

Domain:

{ − 1 ,  0 ,  4 }

Range:

{ 9 ,  − 1 ,  4 }

Remove parentheses.

{ ( − 1 ,  9 ) ,     ( 0 ,  − 1 ) ,     ( − 1 ,  4 ) ,     ( 4 ,  9 ) }

Find the inverse.

No inverse can be found

Anna is following this recipe to make biscuits.
Anna uses 660 mL of syrup.
How many grams of margarine will she need?

Recipe: Makes 24 biscuits
60 g sugar
110 mL syrup
220 g oats
120 g margarine
40 g chocolate​

Answers

Answer:

720 grams

Step-by-step explanation:

660 mL(amount she used) / 110 mL (amount from the recipe) = 6 times

So Anna uses 6 times the amount of syrup from the recipe.

Therefore she also needs 6 times more margarine than it is written in the recipe, which is 120 g * 6 = 720 g

Answers

Answer:

Step-by-step explanation:

Equations

Ron and Howard work at Amazon.

Ron works x hours each week for 7 days. This means he works 7x hours a week.

Howard works one more hour per day than Ron, thus he works x+1 hours per day. This means he works 7(x+1)=7x+7 hours a week.

Howard works 7x+7 hours in a week
