Answer: y = 25x + 50
Explanation: the total cost if the rental is a linear function of the number of days of the rental (x). Each day costs $25, so that is the slope of the line. Since there is also a one-time fee, independent of the number of days, this amount $50 represents a vertical shift of the line on the graph, by 50. y=25x+50 is an algebraic expression of that.
Answer:
r=5
Step-by-step explanation:
5x5x5=125
Answer:
10
Step-by-step explanation:
712.9 / 10 = 71.29
Answer:
y=
x-3
Step-by-step explanation:
slope intercept form is y=mx+b
b is y intercept
so we plug the coordinate into the equation
-3=(0)+b
-3=b
so y intercept is -3
so we then write our equation which is,
y=x-3
Answer:
(y+1)/5
Step-by-step explanation:
you meant f^-1(x) ?
let y= 5x-1
Make x subject of formula
y+1=5x
x=(y+1)/5
f^-1(x)=(x+1)/5 replace y by x
