5/8+7/6+9/4

--------------------------------------------------------------------------------------------------------------------------

5/8 = 15/24

7/6 = 28/24

9/4 = 54/24

Can you finish it now ???

Correct.....!!!

Let h = the hours worked in a week....and we have

2h + 15 = 3h - 15   add 15 to both sides, subtract 2h from both sides

30 = h

She worked 30 hours each week

-(4(-10)+1)

- [ 4 * -10   + 1  ] =

- [ -40  + 1 ] =

- [ -39 ]=

39

5y+4=4y+5    subtract 4, 4y  from both sides

y = 1    

That was pretty easy, huh???

I assume you want to graph this???

If so....notice that when x = 0, y = 3

And when y = 0, x = 12

So....we have the two points   (0, 3) and (12, 0)

Plot these on a graph..........connect them with a line.......voila  !!!!!  ........there's your graph  !!!!

2+6x=1-x      add x to both sides........subtract 2 from both sides

7x = -1         divide both sides by 7

x = -1/7

I don't think you can....however.....the calculator can be set to either degree or radian mode at the bottom left......!!!!!

e ^{-x + 4}   for  x =

 [-2 , 4 , 5 ]   = [e^6, 1, 1/e]  =  [403.4287934927351226,  1,  0.3678794411714423 ] 

LOL!!!....NO, THEY ARE NOT !!!!!.......they are Melody's mis-matched "leggings"......!!!!!!
