Answer:
The required function is:

Step-by-step explanation:
We have to represent the given scenario as an equation or function
Let x be the number of miles driven in a week
Let C(x) be the function of the number of miles driven
As it is given that charges are 150 per week, these charges are constant so they will be used as it is.
It is also given that the cost of car is 0.45 per mile so for x miles the cost will be:
0.45x
Combining both terms, we get

Hence,
The required function is:

Its red because 25+7(1)=25+7=32, 25+7(2)=25+14=39, and so on
Answer:
120
Step-by-step explanation:
Angles opposite to equal sides are equal .
30 + 30 + x = 180 {Angle sum property of triangle}
60 + x = 180
x = 180 - 60
x = 120
The answer is 3 because percentage is out of 100. therefore 10 is 10 percent of 100, etc
