Answer:

A function gives for each element of the domain only one element of the range.

Step-by-step explanation:

We have to choose from the statements in the options that define a function correctly.

From my point of view the statement that a function gives for each element of the domain only one element of the range, defines a function properly.

Geometrically it represents that if we draw a vertical line in the graph of the function that intersects the graph at more than one points then this is not a function, this is only a relation. (Answer)

julio has found that his new car gets 36 miles to the gallon on the highway and 31 miles per gallon in the city. he recently dro

SashulF [63]

Answer:

Miles he drove on highway = 180 miles

Miles he drove in the city = 217 miles

Step-by-step explanation:

Lets assume that gallon used on highway = x

Miles driven on highway = y

(I) 36 miles per gallon on the highway.

36x = y equation 1

(II) 31 miles per gallon in the city.He recently drove 397 miles on 12 gallons of gasoline

31(12-x)= 397-y equation 2

372-31x= 397-y

Combine the constants:

-31x= 397-372-y

y-31x = 25

Now substitute the value of equation 1 in equation 2

y-31x=25

36x-31x=25

5x=25

Now divide both sides by 5

5x/5=25/5

x=5

Now substitute the value x=5 in equation 1

36x=y

36(5)=y

180= y

Now subtract the miles driven on highway from recently drove miles to get the miles driven in the city.

397-y = 389 - 180

= 217

Therefore,

Miles he drove on highway = 180 miles

Miles he drove in the city = 217 miles ....
