Y=kx
k=constant of variation
given
k=12
y=36
36=12*x
divide both sides by 12
3=x
x=3

Step-by-step explanation:
Work Backwards!
1.- 260 - 110 = 150 children
2.- 150 X $2.50 (rate of children) = $375
3.- $815 - $375 = $440
4.- $440/$4 (rate of adults) = 110 Adults
3x^2-18+5=47
3x^2 = 60
x^2 = 20
x = 4.472 , x = - 4.472
Answer:
D) 1.0
Step-by-step explanation:
if y = 1 then x = 1
