15²-9²= x² use Pythagoras' theorum and square the two smaller sides to get the square of the hypotenuse (the diagonal) then rearrange this to get the above calculation
I'm sorry I can't answer that but I know something so you can answer that. search in browser 'quickmath' all your problems, equations and more can be solved
Step-by-step explanation:
I hope it helps trust me
(-infinity,-5]
(-infinity,-3]
<span>First put this into slope intercept form;
Your y-intercept is -3 and the slope is
So you would plot the y-intercept (point (0,-3) and from there move down 1 unit and to the right 1, that is your next point, then plot one more point, then connect with a solid line then shade with your pencil the area above the line.
Hope you understand
