bearing in mind that perpendicular lines have <u>negative reciprocal</u> slopes.
now, they both intersect at 0,0, namely they both pass through it, we know the slope of the first one, so

so, we're really looking for the equation of a line whose slope is 2, and runs through (0,0).

Answer: Eric: The 10 is the initial amount, the 1/2 is the decay factor or the rate at which it decreases, and the exponent w is the number of weeks it decreases by factor 1/2, or the time. Andrea, 1 is the initial amount, 0.2 is the decay factor or rate of decrease, w is time passed or number of weeks it's decayed by the factor.

Answer:
48.9
Step-by-step explanation:
Subtract 2 from 99.8 = 97.8
Divide 97.8 by 2 - 48.9
