When a line is perpendicular, the slope is the negative reciprocal. Therefore, since the slope is 4, the slope of a line perpendicular is -1/4
Step-by-step explanation:
{(2)³}⁸×{(2)³}-⁵
2²⁴× 2-¹⁵
2²⁴-¹⁵. ( subtract 24 and 15)
2⁹= 512
So...
8×8×8= 512
hence
8³ Answer
I=prt.
I= $200 X 4% X 7.
I= 8 X 7.
I= 56. Her total interest earned was $56 :)
