X in the first equation
because 3x + 6y = 9 can be reduced by dividing by 3, thus, giving u
x + 2y = 3.....x = -2y + 3...which u would sub in for x in the other equation
You should try this (20+7)+(10+5)=42
Answer:
A or B.
A seems like best answer so far to me.
Step-by-step explanation:
Hope this helps!
Because it’s perpendicular, the slope must be -1/2, which is the opposite of 2. You can put the points into y-3=-1/2(x-4) and simplify if need be.
