Up and down is vertical. At w = 0 there's a vertical asymptote.
The value of c is { c | c ∈ R, c ∉ {-1,0,2,12} }.
c is a number such that it is not in the set {-1,0,2,12} else we end up with a domain value having multiple range values, contradicting with the definition of a function.
Answer:
67/20
Step-by-step explanation:
67/20=3.35
C= .75d because when you subtract 25 from 100 you get 75 and when you will multiply .75 by d you will get the discounted price.
Y = -3/4x + 5.....the slope here is -3/4...but for a perpendicular line, we need the negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is 4/3 (see how I flipped the slope and changed the sign)
now we use y = mx + b
slope(m) = 4/3
(3,-1)...x = 3 and y = -1
now we sub and solve for b, the y int
-1 = 4/3(3) + b
-1 = 4 + b
-1 - 4 = b
-5 = b
so ur perpendicular line is : y = 4/3x - 5
