Answer:
S(-7,0) , 2/7
Step-by-step explanation:
To get coordinates of P we can see that
14*(2/7)=4
Now, to get coordinates of S, we have this equation :

Multiply by 7 each side :
2x=-14
x=-7
y=0
No, because 1 yard equals 3 feet so therefore 2 feet can't equal 6 yards. 18 feet equals 6 yards.
Answer:
A. $6
Step-by-step explanation:
We are given the table representing the number of days and the total charges in dollars.
So, the rate of change of the amount is given by, 
The linear equation representing the situation is,
Total charges = Fee per days + Fixed amount.
i.e. Total charges, y = Rate multiplied by x + Fixed amount (c)
So, substituting the rate and the point (0,6), we get,
6 = 10 × 0 + c
i.e. c = 10
Thus, the equation is,
Total charges, y = Rate multiplied by x + Fixed amount (c)
i.e. y = 10x + 6
Hence, the fixed amount charged is $6.
So, option A is correct.
Answer:
the y adds 9 for every one x
Step-by-step explanation:
Part A: The table does not represent y as a function of x. We can not input 1 and get 4 and 2 as outputs ( or input 3 and get 12 and 6 as outputs ).
Part B : f (120) is a cost for renting a peddleboat for 120 hours;
f (120) = 20 + 10 * 120 = 20 + 1,200 = 1,220.
