The system of inequalities below describes the relationship between cori’s age, c, and livy’s age, l. dok 2

c + l > 43
c - 4l < 3

which of the following could be the ages of cory and livy?
livy could be 13 years old, and cori could be 35 years old.
livy could be 15 years old, and cori could be 28 years old.
livy could be 33 years old, and cori could be 10 years old.
livy could be 20 years old, and cori could be 85 years old.

Livy could be 13 years old, and Cori could be 35 years old.

Step-by-step explanation:

Given : The system of inequalities  describes the relationship between Cori’s age, C, and Livy’s age L.

C + L > 43

C - 4L < 3

We have to determine the ages of Cory and Livy.

We will plot both the inequality in a graph.

Thus, below attachment shows the graph of the two given inequality

Let x axis represent the Cori’s age, C, and y - axis Livy’s age L.

Now we plot the given ages in the graph and those points lies in intersection will given the ages of Cori and Livy.

Thus, Only  (35 , 13) lies in the intersection,

We reject other points as the lies on dotted edges of graphs.

Thus, Livy could be 13 years old, and Cori could be 35 years old.

it is d 3yz2 – 3z2 – 5y + 7
