Answer:
120
Step-by-step explanation:
angle AC = 180, so 3x = 180, so x = 60. Accoding to the Adajacent Angle Theorem, 2x = AB, so AB = 120.

Answer:
The tip would be $1.44, so the total would be $13.44
Step-by-step explanation:
To find the tip you take the bill ($12), and multiply it by the percent of tip given (12%), but it has to be in decimal form. 12% in decimal form is .12. 12 times .12 is 1.44. Add $12 to that to get $13.44.
Answer:
(-1, 5)
(0, 3)
(2, -1)
Step-by-step explanation:
we have
Remember that
If a ordered pair is a solution of the given function, then the ordered pair must satisfy the given function
<u><em>Verify each case</em></u>
case a) (-2, -1)
substitute the value of x and the value of y in the given function and compare the result
---> is not true
therefore
Is not a ordered pair of the given function
case b) (-1, 5)
substitute the value of x and the value of y in the given function and compare the result
---> is true
therefore
Is a ordered pair of the given function
case c) (0, 3)
substitute the value of x and the value of y in the given function and compare the result
---> is true
therefore
Is a ordered pair of the given function
case d) (1,0)
substitute the value of x and the value of y in the given function and compare the result
---> is not true
therefore
Is not a ordered pair of the given function
case e) (2, -1)
substitute the value of x and the value of y in the given function and compare the result
---> is true
therefore
Is a ordered pair of the given function
