So far you have mostly worked with equations. there are special types of equations, called functions, that have exactly one output for every possible input into the equation. an example of this in the real world is the amount of money you are charged at a store: the input is the item you are purchasing, and the output is the money you are charged. individual items have one price, so this is an example of a function. can you think of any other examples of functions? why might this type of equation be useful?

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
