Answer:
70 percent
Step-by-step explanation:
Find how many acres were not planted with alfalfa by subtracting 27 from 90:
90 - 27
= 63
Find what percent this is by dividing it by 90:
63/90
= 0.7
So, 70 percent of the acres weren't planted with alfalfa.
Simple, since you want to find y, in y=mx+b form, move everything to the other side.
1/2x-y=4
Move 1/2x
1/2x-y=4
-1/2x -1/2x
Making it look like,
-y=4-1/2x
Divide by the negative 1 in front of the y,
-y=4-1/2x
/-1 /-1
y=-4+1/2x
or
y=1/2x-4
Thus, this written in y=mx+b form, y=1/2x-4.
