TIMER what are the x - intercepts
A. x=1,x=16
B. x=15
C. x=3, x=-5
D. x=-3, x=5

Intercepts of lines review (x-intercepts and y-intercepts) The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.

the answer is subjective. i personally agree with the first answer for this question.

if one isn't strictly talking about objects then the correct answer would be 'my eyes' since according to this riddle i am asleep and in order to answer/open the door i need to open my eyes first of all.

however, if one is specifically looking for an object, then the first thing i would open would be the door

hope this !
