A, because:
Hardcover: 0.35
Buys hard cover and non-fiction: 0.35 x 0.55 = 0.1925
40%
40 percent of 25 is 10
10/25x100 and you will get your answer which is 40
Answer:
y= - 5/2x - 2
Step-by-step explanation:
Y=2/5x + 2
Making it perpendicular, the slope will change to it's reciprocal and swap operations (+ becomes -). 2/5 will be -5/2. We already know the y-intercept which is -2, so simply put, the equation in slope-intercept form is y = -5/2x - 2
