The answer is the last one; to express very large or small numbers.
We use it so we can show big or very small numbers in an easier way.
Tan(x)= 33/105
x = arctan(33/105)
x = 17.44718842 degrees.
She has 7 more roses. you can subtract to find the difference. 14-7=7
I’m not sure if you want the answer or how to do i’ll just give you both.
multiply the bottom by -4. then it should look like:
8x-6y=-6
-8x+16y=56
then cancel out the x’s and add/subtract the others, giving you: -2y=50. then divide 50 by -2 giving you: y=-25. then find x. plug in y to one of the equations. i usually do the one that hasn’t been messed with. 8x-6(25)=-6. then solve it like a normal two-step equation.
so the answer is: (18,-25)
It will be y+3y and the answer is 4y
