2 answers:
Answer:
(1,1)
Step-by-step explanation:
we have
we know that
If a ordered pair is a solution of the inequality, then the ordered pair must satisfy the inequality
<u><em>Verify each ordered pair</em></u>
case A) we have
(5,0)
Substitute the value of x and y in the inequality
----> is not true
therefore
The ordered pair is not solution to the inequality
case B) we have
(0,-2)
Substitute the value of x and y in the inequality
----> is not true
therefore
The ordered pair is not solution to the inequality
case C) we have
(1,1)
Substitute the value of x and y in the inequality
----> is true
therefore
The ordered pair is a solution to the inequality
case D) we have
(-5,-6)
Substitute the value of x and y in the inequality
----> is not true
therefore
The ordered pair is not solution to the inequality

To find both coordinates and radius we need to make this equation in circle form:
(x-a)^2 + (y-b)^2 = r^2
x^2 - 2*1/2*x + 1/4 - 1/4 + y^2 - 2*1*y + 1 - 1 = 0
Here we are adding and subtracting numbers in order to get square binomial.
(x - 1/2)^2 + (y-1)^2 = 5/4
coordinates of center are (1/2,1) and the radius is √

<h2>I. 336 ft²</h2>Step-by-step explanation:
We have
two right triangle with legs 6ft and 8ft
one rectangle 8ft × 12ft
one rectangle 6ft × 12ft
one rectangle 10ft × 12ft
The formula of an area of a right triangle:
a,b - legs
Substitute:
The formula of an area of a rectangle:
l,w - length, width (dimensions of rectangle)
Substitute:
