Ineeed this ∠1 and ∠2 are supplementary angles. m∠1=4x+3 m∠2=3x−5 what is the value of x? a. x = 26 b. x = 178 c. x=1787 d. x=927

4x + 3 + 3x - 5 = 180

7x = 182

x = 26

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
