Answer:
21+/-sqrt(253)=x
So one value for x is 21+sqrt(253)
and another is 21-sqrt(253)
Problem:
Given (21,7) and (x,1), find all x such that the distance between these two points is 17.
Step-by-step explanation:
Change in x is x-21
Change in y is 7-1=6
distance^2=(change in x)^2+(change in y)^2
17^2=(x-21)^2+(6)^2
289=(x-21)^2+36
Subtract 36 on both sides:
289-36=(x-21)^2
253=(x-21)^2
Take square root of both sides:
+/-sqrt(253)=x-21
Add 21 on both sides:
21+/-sqrt(253)=x
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Given
 A baby kitten, gained 120 grams of weight in 1/3 of a month.
he gain in 1 month
Solution
1/3 month =120gram weight
1 month =120×3
 =360 gram is the answer
 
        
             
        
        
        
Only x-intercept because if you want to know about x-intercepts so y will be zero (y=0) 
then 0 =4x^2 -12x + 9
0=(2x-3)(2x-3)
0=2x-3
so x=3/2 that is x-intercept
        
                    
             
        
        
        
It's irrational, number and intiger
        
             
        
        
        
The amount each friend does pay is £9.75
<h3>How to calculate the pay of each friend using fractions and arithmetic operations?</h3>
We are going to find 5% of the total amount paid and divide it by the numbers of all the friends to determine the amount paid by each one of them.
From the given information:
- The 5% of 130 = £6.5
 - Total amount paid = £130 + £6.5 = £136.5
 
Therefore, the cost of each friend is = 
The cost of each friend = £9.75
