Choice 1:
= 5 * [5^3 / (2/5)]^2
= by looking at the equation, it's kinda not equal to 125
choice 2:
= [5^3 / 5^4]^-3
= 5^-9 / 5^-12
= 5^(-9 - -12)
= 5^3
= 125
choice 3:
= 5^-2 / 5^-5
= 5^(-2 - -5)
= 5^3
= 125
choice 4:
= 5 * 5^5/5^3
= 5 * 5^(5-3)
= 5 * 5^2
= 5^3
= 125
So the expression that is not equal to 125 is:
<span>5 times the quotient 5 cubed over two-fifths, raised to the second power</span>
The first hour is free, and the rest charges is $2.50
Let x be the time.
Let y be the total
Your equation will look like
When x < 2, y = 0
When x > 1, y = $2.50(x)
So:
1 < x < ∞ for hours, then equation will look like:
y = total amount
$2.50 is cost (remember that the first hour is for free, and so you subtract $2.50 from the total.
$2.50x - $2.50 = y should be your equation.
