Eight less than one-fourth of a number is 4
enyata [817]

1/4n-8=1/4 would be first because it says less than so you switch it. then you put the 8 since it's in the same subtraction problem. Then the word "is" indicates the equal sign. and the n represents "a number" since it is unknown.

Determine which relation is a function.
jolli1 [7]
To determine if it is a function or not, you can not have a vertical line drawn down the graph touch 2 of the graphed points. That means that you can not have 2 points with the same x value and different Y value. The first set of points satisfies this and is your answer. Hope that helps.

A taxicab service charges a flat fee of $7 plus an additional $1.25 per mile driven. Show the relationship between the total cos
Zarrin [17]

Answer with Step-by-step explanation:

We are given that

Flat fee of taxicab=$7

Cost of one mile=$1.25

1.We have to show that relationship between total cost and the number of miles driven.

2.We have to find independent variable and dependent variable

3.We have to write an equation to model the relationship and make a  table to show the cost of 4 to 10 miles.

1.Let x be the number of miles driven by taxicab and total cost y of taxicab.

According to question

y=1.25x+7

This is a relation between number of miles drive and total cost.

2. Independent variable : It is that variable which does not depend on value of another variable .

Dependent variable : it is that variable which depend on value of  another variable.

We can see that y depend on x and value of x does not depend on  any value.

Therefore, y is dependent variable and x is independent variable.

Substitute x=4 then we get

y=1.25(4)+7=$12

Substitute x=5 then  get

y=1.25(5)+7=$13.25

y=1.25(6)+7=\$14.5

y=1.25(7)+7=$15.75

y=1.25(8)+7=$17

y=1.25(9)+7=$18.25

y=1.25(10)+7=$19.5
