The answer is 11% let me explain 18 people under the age of 15 travel by car but that's not 18% because the total is 165 not 100. so just find out what is 11% of 165 and its 18 which means 11% is the correct answer.
No. For a set of data to be points produced by a function, each value of x can produce only one value for y. Otherwise it fails what is called the "vertical line test". The definition of a function requires that only one value of y can exist or for one value of x, or in other words one input can produce only one output.
In this case you have points (1,-2) and (1, -3), obviously -2 does not equal -3 and so there are two outputs, y, for one single input, x=1. Therefore the data can not be from a function.

Answer:
perpendicular slope = -

given a line with slope m then the slope of a line perpendicular to it is
= - 
the given slope m = 4, hence
= -
Answer:
and 
Step-by-step explanation:
Given:
.......................... equation i
........................ equation ii
since y is equals to the two functions , we can equate the two values of y . That is , equate equation i and ii , we have
Add 
to both sides , we have
subtract 3 from both sides , we have
divide both sides by 4 , then
substitute into equation i to get the value of y , that is
Therefore :
and
