$0.30x=y should be the answer because there is a 30cent fee for every day and x represents how many days it's kept therefore you would add 30 cents for every day it's kept so it's valid to say $0.30x=y becaue the 30 cents times the total of days it's kept = y (the toatl)
Answer:
Step-by-step explanation:
Given Data:
Length of rectangle = L = 
------->(Equation 1)
Area of rectangle = A = 
square inches ------->(Equation 2)
To find out:
Width of rectangle = W = ?
Formula:
Area = A = L×W
Solution:
For complete division check the attached image.
inches
∠s + ∠y are complementary
∴ ∠s + ∠y = 90°
∠s = 4(∠y ) -100
s + y = 90
4y - 100 + y = 90
5y = 90 + 100
5y = 190
y = 38
Ans: y = 38°
(0,5)
(4,-2)
(-16,17)
just substitute the x and y values from each coordinate into the equation
