Answer: 16
Step-by-step explanation:
64/4=16
n=16
Answer: 1, 2, 5
Step-by-step explanation:
The first equation is true because angles in a triangle add to 180 degrees.
The second equation is true because both sides equal 180 degrees (left hand side is a straight angle, right hand side is the sum of angles in a triangle)
The third equation is not true because z = 180 - y, and 180-y+w+z is not 180.
The fourth equation is not true because z=180-y, and 180-y=w+y is not always true.
The fifth equation is true by the exterior angle theorem.
The domain of the first one is -3,-1,0,2,7. The range is -7,-3,-1,3,7.
For the second, the domain is -5,-4,0,1,2. The range is -4,2,2,3,4.
Domain is just the x-values
Range is just the y-values
