Step-by-step explanation:
One inequality could be x > 3. So when x = 4 this is true because 4 is greater than 3.
1. The given rectangular equation is
.
We substitute
.

Divide through by 



2. The given rectangular equation is:

This is the same as:

We use the relation 
This implies that:



3. The given rectangular equation is:

This is the same as:
We use the relation
and 
This implies that:

Divide through by r


4. We have 
We substitute
and 

This implies that;



5. We have 
We substitute
and 

This implies that;



Answer:
Correct choice is D
Step-by-step explanation:
Given the system of two equations:

Fro mthe first equation

Substitute into the second equation
instead of y:

Note that
then the second equation will take look

you must substitute x in the equation given :)
examples:
when x is -2
therefore, y = 2(-2) + 3
y = -1
when x is 0
therefore, y = 2(0) + 3
y = 3
when x is 1
therefore, y = 2(1) + 3
y = 5
when x is 3
therefore, y = 2(3) + 3
y = 9
for (b) you only have to plot based on the table ;)
hope this helps
