Answer:
All real numbers
Step-by-step explanation:
The domain of the function is the set of real values that can be substituted into a function to produce a valid output. Any real number can be substituted into the function (y = x), and produce a valid output. Thus, the domain is all real numbers.
Answer:
You can solve this by having 2 different equations and setting both of them to 180 because they are supplemetnary anhles
Step-by-step explanation:
so for abc the equation= 180, then solve
then for the other angle cbd=180, then solve
Answer:
9/4
Step-by-step explanation:
2 1/4 = 9/4 From mixed fraction to an improper fraction: "the numerator of the improper fraction" = "denominator" xx "the whole number" + "the numerator of the mixed fraction" The denominator remains as it is. So 2 1/4 = (4 xx 2 + 1)/4 = 9/4
Answer:
i wanna say A, but i am unsure...
Step-by-step explanation:
Step-by-step explanation:
since the 2 lives are parallel, this makes the 2 triangles (above l and the larger one above m) similar.
and that means their angles are the same.
and that means that the third angle in the small triangle above l is also y°.
and now, remember, the sum of all angles in a triangle is always 180°.
so,
180 = x + y + z = x + 20 + 60
x = 180 - 20 - 60 = 100°
so, B is correct.
