A straight line is 180 degrees
$a = 180 - 40 \\ a = 140$

140 is not a straight line, it would be obtuse, 180 degrees is a straight angle

Your friend evaluates the expression when m = 10. is your friend correct? Explain your reasoning.

trapecia [35]

Answer:

yes

Step-by-step explanation:

3 * 10 (m) = 30 so 30 - 6 = 24. 3(10) - 6 is basically the same thing just written different, so it equals 24 too. 3(4) just means 3 times 4 ,which equals 13. Hope that made sense lol

Answer:

A) Enterprise: E(x) = 50 +0.25x; Hertz: H(x) = 30 +0.45x

B) see attached graph

Step-by-step explanation:

A) We choose to compare Hertz (lowest daily charge) and Enterprise (lowest mileage charge). In each case, the total charge will be the sum of the daily charge and the product of the mileage charge and number of miles (x).

Enterprise: E(x) = 50 +0.25x

Hertz: H(x) = 30 +0.45x
