Answer:
$103.75 for 8 hours
Step-by-step explanation:
8hr * 60min = 480min (for the total trip)
480min / 30min = 16 (30 minute intervals in her trip)
If the first half hour is a $25 dollar charge then,
$25 * 1 + $5.25 * 15 = $103.75 (for 8 hours)
Answer:
15y / 8
Step-by-step explanation:
Multiplying by 2 to get the common denominator.

The first sentence is not true in general. Consider the equation
. There are no solutions. Now consider
. There is only one solution,
.
But whatever. You're asked to demonstrate that
has two solutions (which is true; the right hand side must be a positive integer in order to have two solutions). This follows immediately from the definition of absolute value, which says
So suppose
. Then
Now suppose
. Then
So two solutions to
are
.
Answer:
4th option
Step-by-step explanation:
note that y = f(x)
locate f(x) = 1 ( output) on the y- axis, then a horizontal line passing through y = 1 intersects with the curve at (- 7, 1 ) and (2, 1 )
the input is then the x- coordinates of these 2 points , that is
x = - 7 and x = 2
