Hello!
Usually when solving equations you do the opposite of PEMDAS. Therefore we add as it is the opposite of addition.
Therefore, our answer is B. Add 15.9 to both sides because it is the inverse operation of addition.
I hope this helps!
12. The inverse relation has the x- and y-values swapped.
The appropriate choice is ...
D. (13, 5)
Mark 2 points on the coordinate grid and draw a line through them
One point would be when x = 0 and y = 1/2(0) + 5 = 5.
and another point is ( 10, 10)
Ok So, 5+3=8x2=16-6=10 :)
