solve for "k", to find the "constant of variation",
then plug it back in the y = kx, to get the equation
now
what's is y when x = -1?
well, just plug that in the equation with the found "k" value,
to get "y" :)
Answer:
-7
Step-by-step explanation:
The relative minimum is the smallest y value
The relative minimum is -7
Step-by-step explanation:
M = L + rL
a.
L = $63.80
M = $121.80
need to find r
121.80 = 63.80 + r×63.80
58 = r×63.80
r = 58/63.80 = 0.91 = 91%
b.
L = $65
M = $146.25
need to find r
146.25 = 65 + r×65
81.25 = r×65
r = 81.25/65 = 1.25 = 125%
Answer:
12 male teachers
Step-by-step explanation:
If the ratio is 3:4, and the number of female teachers is 16, then the number of male teachers must be 12. This can be confirmed by multiplying both 3 and 4 by 4, or 12/16 = 3/4.
