You want it to be greater than and equal to 2. A closed circle means to include 2 so you want a closed circle and to the right is to bigger numbers so you want to the right. So the answer is b. Number line with closed circle on 2 and shading to the right.
Answer:
5x + 2y = 9
Step-by-step explanation:
Find the slope of the line that is perpendicular to 2x - 5y = 7 :
m= 
Find the y - intercept of the function:
b = 
substitute m= and b = into y = mx + b :
y = 
+
y = 5x + 2y = 9
For this case we have the following expression:
We follow the steps below:
We subtract 4x on both sides of the equation:
We subtract 10 from both sides of the equation:
Now, we must complete squares.
When we have an equation of the form:
, if we want to complete squares we must subtract c on both sides of the equation obtaining:
The square is completed by adding to both sides of the equation:
So, we have left:
In the given expression we have:
And to complete the square we have:
Rewriting we have:
We factor the left side of the equation, that is, we look for two numbers that when added together result in -8 and when multiplied as a result 16. We have:
So, we have:
Answer:
The intermediate step is to complete squares
