You use the formula Interest=principle (rate) time or i=prt. If you use that formula to solve, your answer will be 3,500. After five years, the balance will be $3,500.

X= 7.5 because you subtract 2.5 from 10 and you get 7.5 which equals X
ANSWER= 30 rides
STEP-BY-STEP EXPLANATION
y=mx+b
m= $0.5 (per ride)
b= $5 (the cost)
x(rides) and y(parents money)
y= 0.5 x + 5
20= 0.5 x +5
20 - 5 = 0.5 x
15=0.5x
x= 
x=30 rides
If f(x)=-3x-5 and g(x)=4x-2, then the value of (f-g)(x) is -7x-3.
The given functions are f(x)=-3x-5 and g(x)=4x-2.
We need to find the value of (f-g)(x)
<h3>What is a function?</h3>
In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
Now, (f-g)(x)=f(x)-g(x)=(-3x-5)-(4x-2)
= -3x-5-4x+2 = (-3x-4x)+(-5 + 2)
= -7x-3
Therefore, the value of (f-g) (x) is -7x-3.
