Answer:
6
Step-by-step explanation: You can set up the equation: 
= 
You square both sides to cancel out the squares which leaves you with 
= n - 4. Then you just solve as normal which ends you up with an answer of 6. You can check this by plugging 6 back into the equation and see that you end up with 
on both sides.
Assuming if you are looking for an equation
I can say that the X-intercept= 16/9
but with an equation it would be 9x/4(-4)
Step-by-step explanation:
1. the table on the left is a function, with the formula : y = x²
2. the table on the right is also a function, indicated by the values of the input are different each others
(V + 200) divided by 2= average of the 2 days
Answer:
-3
Step-by-step explanation:
-2(5x+1)=58+10x
=>-10x + -2 = 58 + 10x
=> -10x -10x = 58 + 2
=> -20x = 60
=> x = 60/-20
=> x = -3
