Answer: 6+2x
Step-by-step explanation:
6 is the fixed cost so you add six regardless of how many kilos you travel. You add the 2x because they charge 2 dollars for every extra kilometer. The x is kilometers(which you don’t know how many you travel.) so you add 6+2x to get the cost.
Linear equation is equation in which each term has at max one degree. The formula for the cost of the journey is y = $6 + $2(x).
What is linear equation?
Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form,
y = mx + c
Linear equation with two variables, when graphed on cartesian plane with axes of those variables, give a straight line.
The given condition can be modelled using a linear relationship.
It is given that there is a fixed charge of $6 and an additional charge of $2 per kilometre. Therefore, the total charge,y can be modeled as,
y = $6 + $2(x)
where x represents the number of kilometres
The formula for the cost of the journey in Words is 6 plus two times of x, where x represents the number of kilometres.
Hence, the formula for the cost of the journey is y = $6 + $2(x).
