Answer:
Step-by-step explanation:
9-4(x-y)=2x+6
9 - 4x + 4y = 2x + 6
9 + 4y = 6x + 6
4y = 6x - 3
y = 3x/2 - 3/4
What you want to do is change the variable positions of X and Y
So it would be a new equation of
x = 1/2y + 3
Then you would need Y to be by itself so you solve for that
x-3 = 1/2 y
then,
2(x-3) = y
Your inverse function is 2(x-3) = y
Hope this helped :D
That mean the awner to question is 3 y is 3 just substract 6 minus 3
Answer:
Step-by-step explanation:
cos theta is 5/13
so, adjacent=5 ,hypotenuse=13 and opposite=?
hypotenuse^2=adjacent^2+opposite^2
13^2=5^2+opposite^2
169-25=opposite^2
=opposite
12=opposite
sin theta=opposite/hypotenuse
=12/13
2/5=0.4
5/8=.625
subtract .4 from .625 and get....
.225
and .225 is 9/40
