Answer:
Amount Jerry earned is $5
Step-by-step explanation:
Jerry is paid $6 per hour.
First we need to find the number of hours he walked the dog.
From 6.40 am to 7.30 am we have 50 minutes. Jerry walked the dog for 50 minutes.
An hour has 60 minutes.
We need to find how much Jerry gets paid for a minute.
Amount paid for a minute =
=$
Therefore,
Amount paid for 50 minutes = $ *
minutes
=$
Question 1:
For this case we have that the function is undefined or discontinuous where the denominator equals 0.
Thus, the function is undefined or discontinuous at +5 and -5.
To find the zeros of the function we match the function to zero and clear "x":
Factoring the denominator, taking into account that the roots are -5 and +5:
We multiply byon both sides of the equation:
ANswer:
Discontinuity: + 5, -5
Zero: x = 0
Question 2:
For this case we propose a system of equations:
x: Be the variable that represents the yellow fish
y: Be the variable that represents the green fish
We manipulate the second equation:
We substitute in the first equation:
So, we have 12 yellow fish in the aquarium.
So, we have 18 green fish.
Answer:
12 yellow fish
18 green fish
