Answer:
y = -3/1x + 4 ...............
Hi i just took the quiz and this is where your point needs to go. Idk how to explain it bc i got it wrong but the dot there is the right answer.
Answer:
2
Step-by-step explanation:
Given the circle: 
To determine the length of the radius, we complete the square.
Step 1: Subtract 4 from both sides

Step 2: Divide the coefficient of x and y by 2, square it and add it to both sides

Step 3: Factorize the Left Hand side and simplify the Right Hand side.

Comparing with the standard form of the equation of a circle

r=2
Therefore, the radius of the circle is 2.
Answer:
The expenditure would be $ 8600
Step-by-step explanation:
If the cost is given by the function
C(x)= 10x + 6 where x is the number of days
The cost for 1 day would be
C(1)= 16 *100 = 1600 $ ( the expenses are in hundreds of dollars)
Then Putting x= 8 in the given equation we get
C(8)= 10(8) + 6
= 86
Multiplying 86 by 100 because expenditure rate per day is in hundreds of dollars
The expenditure would be $ 8600
