Answer:
The slope is $0.1774 / pounds
Step-by-step explanation:
From the question we are told that
The weight of the rat is
The cost of feeding the rat per week is $4.50
The weight of a Beagle is
The cost of feed a Beagle per week is $9.20
Now the slope can be evaluated mathematically as
substituting values
$0.1774 / pounds
Answer:
He subtracted -5 from both sides, not -6
Step-by-step explanation:
The inequality that we have to solve in this problem is
To solve the inequality, we proceed as follows:
1)
First, we isolate the term in x. To do that, we add -6 on both sides of the inequality, and we find:
So, this is now the new inequality.
2)
Then, we divide both sides of the equation by 5; we get:
3)
Finally, we change sign to the inequality, so we get:
So, the student's error is that he subtracted -5 from both sides, not -6.
