First, determine the center of the circle by getting the midpoint of the points given for the circumference.
midpoint = ((0 + 0)/2, (3 + -4)/2)
midpoint (0, -0.5)
Then, we get the radius by determining the distance from either of the circumferential point to the center.
radius = √(0 - 0)² + (3 +4)² = 7
The equation for the circle would be,
x² + (y + 0.5)² = 7²
Answer:
For each hundred-thousand-dollar increase in the listing price, the sales price is predicted to increase by $110,000.
Step-by-step explanation:
The sales price is not predicted to increase by $1.1; it is predicted to increase by $110,000 because S is measured in hundred-thousands of dollars. The sales price will not decrease by $110,000; it is predicted to increase by $110,000.
The given inequality is 2.5x + 4y ≤ 60. x is the bags of chips and y is the jars of salsa,
Replace x and y in the equation with the possible answers and solve:
A) 10 chips and 2 salsas:
2.5(10) +4(2) = 25 + 8 = 32 This is less than 60 so is a solution.
B) 20 chips, 2 salsas:
2.5(20) + 4(2) = 50 + 8 = 58, this is less than 60 so is a solution.
C) 14 chips, 5 salsas:
2.5(14) + 4(5) = 35 + 20 = 55, this is less than 60 so is a solution.
D) 18 chips , 6 salsas:
2.5(18) + 4(6) = 45 + 24 = 69, this is greater than 60 so is not a solution.
18 bags of chips and 6 jars of salsa is not a solution.
