Only hole of function is at <em>x=(-4)</em>
Step-by-step explanation:
Given the function is
In order to find holes of any function, you should find when function is becoming undefined or say " infinity"
Given function is polynomial function.
It will become undefined become denominator become zero
Solving for x value when denominator become zero
we get possible holes at x=(-4) and x=(-5)
Check whether you can eliminate any holes
Now, Solving for x value when numerator become zero
x=(-5) and x=(-2)
x=(-5) is common is both numerator and denominator.
So that, we can eliminate it.
Therefore, Only hole of function is at x=(-4)

We are going to continue the process; this time we are going to evaluate both functions at x=2.4:
For our first function:
For our second function:
To the nearest tenth:
We can conclude that the positive solution of our functions to the nearest tenth is
.
Answer:
70 -20x = 60 -15x
Step-by-step explanation:
The amount of money left on Josh's card is ...
70 -20x
The amount of money left on Jessica's card is ...
60 -15x
These amounts are the same when ...
70 -20x = 60 -15x
_____
<em>Additional comment</em>
The solution to this equation is ...
10 = 5x ⇒ x = 2 . . same amount after purchase of 2 pizzas
