Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Note ∠ Q is a right angle = 90°
Sum the angles and equate to 180
7b + 14 + 6b + 11 + 90 = 180, that is
13b + 115 = 180 ( subtract 115 from both sides )
13b = 65 ( divide both sides by 13 )
b = 5
Thus
∠ R = 6b + 11 = 6(5) + 11 = 30 + 11 = 41°
∠ S = 7b + 14 = 7(5) + 14 = 35 + 14 = 49°
∠ Q = 90°
The answer would be the greater than sign such as >... the whole equation would be 9*4-2x>2(9-x)
A function is an equation that has only one answer for y for every x. This means that:
Set A and Set C are functions because their y values don’t repeat.
Set B is NOT a function because the 2 in the y values repeats twice.

Answer:
5.50$
Step-by-step explanation: The first 5 minutes are 3$, and the additional 10 minutes are .25$ a piece. You multiply 10 minutes by .25$ to get 2.5$. Now, you add the 3$ and 2.5$ to get 5.50$.
