Martha claims that " the sum of two acute angles will form another acute angle" She measured and came up with the following pairs of angles, which one is the counterexample to her statement? (Write the letter of your answer)

A . 30 degrees , 40 degrees

B. 20 degrees , 60 degrees

C. 45 degrees , 45 degrees

D. 40 degrees , 40 degrees

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

answer: ur v dumb

step-by-step explanation:

slope is 35 and 20 miles is the y-intercept.

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.
