Answer:
x^2-6x+y^2+4y=-4
Step-by-step explanation:
I am assuming you want the equation of the circle. We know that the equation of a circle is (x-h)^2 + (y-k)^2 =r^2, where r is the radius, and h and k are the x and y coordinates of the center respectively. We can solve for this by plugging in the numbers.
(x-3)^2+(y+2)^2=3^2
x^2-6x+9+y^2+4y+4=9
x^2-6x+y^2+4y=-4
Use the formula y2-y1/x2-x1
-3 - 0/ 4 - 16 = -3/-12 = 1/4
so the slope is 1/4
Answer:
Step-by-step explanation:
Well.. First of all, the question says that we are working with a rectangle..
So, the rectangle has a length and width. I'll call them L and w.
Look at this phrase: " length that is one foot less than twice its width"
it means, in a algebraic language: L = 2w - 1
Let's analysis the next phrase: "it the area of the rectangle is 91 square feet"
So, A = 91 ft²
But you have to remember that the rectangle area is a product of L and w.
L x w = 91
They are the following equations that you could be used to solve the system of equations.
Now, you have a system of equations and I suggest you to solve it using the substituition method.
L = 2w - 1
L x w = 91
