Answer:
ABE
Step-by-step explanation:
Perpendicular means the slope of the line and the answer are reciprocal to each other.
The slope of the line is -1/2, which means the slope of the answer should be 2.
From A we got: y=2x-1
B:y=2x
C:y=-2x+1
D:y=-1/2x-2
E:y=2x-3
So the answer is ABE
Answer: = 32
40 x 80 / 100 = 32
0.4970
I might be wrong
I thought if you try to do an exponent on a zero, then the answer would always be undefined...

Hoped this helped!
