Consider the function represented by the equation x – y = 3. What is the equation written in function notation, with x as the independent variable? f(x) = y + 3
f(x) = –y – 3
f(x) = –x + 3
f(x) = x – 3

f(x) = x - 3

Step-by-step explanation:

x - y = 3

-y = 3 - x

y = x -3

f(x) = x - 3

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
