Answer:
<h2>d(P, Q) = 6</h2><h2>d(Q, R) = 5</h2>
Step-by-step explanation:
The formula of a distance between two points A(a) and B(b):
<h3>d = |b - a|</h3>
We have P(x + 3), Q(x- 3), R(x + 2).
Substitute:
d(P, Q) = |(x - 3) - (x + 3)| = |x - 3 - x - 3| = |-6| = 6
d(Q, R) = |(x + 2) - (x - 3)| = |x + 2 - x - (-3)| = |2 + 3| = |5| = 5
 
        
             
        
        
        
Answer:
5.75
Step-by-step explanation:
for a 15% increase, you multiply 5.00 x 1.15. you then get 5.75. hope this helps!
 
        
                    
             
        
        
        
For this problem I would change:
2x + 3y = 25 into 
-2x - 3y = -25 
Then, I would add up both equations by lining them up top of another. 
 5x + 3y = 31
+ -2x - 3y = -25
3x = 6 
x = 2
Now that you have x, solve for y. 
5x + 3y = 31
5(2) + 3y = 31 
10 + 3y = 31
3y = 21 
y = 7 
So, x is 2 and y is 7. 
Check to see if the values are correct by plugging them into the other equation. 
2x + 3y = 25
2(2) + 3(7) = 25
4 + 21 = 25
25 = 25 
Since the values are correct, the solution to this problem is A (2, 7). 
        
             
        
        
        
• Im sorry but we doesnt know the x number :( but dont worry to plot the diagram: 
- substitute the number x (given) into the equation f(x) 
- example: f(x) = x + 9 / x - 3
- then x given is 4 
- therefore, f(x) = (4) + 9 / (4) - 3
- f(x) = 13 / 1 or 13
- then you plot at 13 on the graph :)
hope this helps ;/
