Xy=-36
x+y=-3
x= -36/y
-36/y + y = -3
-36 + y^2 = -3y
y^2 +3y -36 = 0
I think you have to use quadratic formula to find the 2 values of y and then plug in for x
Answer:
Step-by-step explanation:
Area of a triangle = 1/2 * Base * height | Plug in values
82.5 = 1/2 * 15 * height | Multiple both sides by 2
165 inches = 15 * height | Divide both sides by 15
Height = 165/15 = 11 inches
Highest common factor is 8
The equation for a circle with the given information would be (x - 4)^2 + (y + 1)^2 = 81.
This is because the base form of a circle is:
(x - x1)^2 + (y - y1)^2 = r^2
In which, x1 is the x coordinate of the center and y1 is the y coordinate of the center. r is the radius of the circle. So we plug in to those and simplify.
(x - 4)^2 + (y - -1)^2 = 9^2
(x - 4)^2 + (y + 1)^2 = 81
