Prove that tanx+cotx=2sec(2x) Thank you! :)
Use the substitution method to solve the linear system. 1/8p+3/4q=7 3/2p-q=4 Thanks.
Use substitution method to solve the linear system. Can someone please check if I did this problem right? Thanks X+y=12 X+3/2y=3/2 Y=21 x=-9
I have another question. So I solved the problem but then I have to put it in an ordered pair form. If I was using the variables "x and y," then it would be (x,y) but what if I were using different variables, in this case s and t, how do I know which one is the x and...
Use the substitution method to solve the linear system. Thanks! s= t+4 2t+s=19
2sinxcosx+4sin^2xcos^2x=0 solve for x in radians between [0,2pi) (I mean that it is sine squared x and cosine squared x not sine to the power of 2x or cosine to the power of 2x)
When the mean is greater than the median, what does it suggests about the data set?
Find the plural that has been formed incorrectly. Then write it in its correct plural form. Dad was hoping to catch several bass and trouts for our suppers. I'm not sure if it's "trouts" or "suppers".
andrea cuts 62 1/2 inches of ribbon into 4 equal hair ribbons. How long was each hair ribbon?
I don't get how you would know which way to shade the inequality when it's true or false. For example the inequality 2x+3y> 12 When I solve it it's y>-2/3x+4 But when I graph the line how would I know which side to shade?
