WebA circle has the equation x 2 + y 2 + 3 x + 6 y + 9 = 0 (a) Find the center ( h, k) and radius r of the circle. (b) Graph the circle. (c) Find the intercepts, if any, of the graph. (a) The center of the circle is (Type an ordered pair, using integers or fractions.) WebMay 15, 2024 · First of all, the graph is of a circle. Anytime you see x^2 + y^2 = r^2, you are dealing with a circle; The center is at 0,0. If it was anything else then x or y or both would be modified. (x+4)^2 + ( y - 3)^2 = 25 does not have it's center at 0,0; Third, the radius of the circle is the square root of r^2. In this case, r^2 = 9 so r = sqrt(9 ...
How do you sketch #f(x,y) = ln(x^2+y^2)#? - Socratic.org
WebThe second inequality is y is less than 2x minus 5. So if we were to graph 2x minus 5, and something already might jump out at you that these two are parallel to each other. They have the same slope. So 2x minus 5, the y-intercept is negative 5. x is 0, y is negative 1, negative 2, negative 3, negative 4, negative 5. WebThe system is: 4y = 2x −9 −6x− 3y = 3 Explanation: Expand the first equation by 3. 6x− 27 = 12y −6x−3y = 3 ... y=2x+91 Geometric figure: Straight Line Slope = 4.000/2.000 = 2.000 x-intercept = 91/-2 = -45.50000 y-intercept = 91/1 = 91.00000 Rearrange: Rearrange the equation by subtracting what ...

Is x^2+y^2=9 a function? + Example - Socratic.org
Web3 Answers. Write it as x 2 + z 2 = y 2. Note that y is the hypotenuse of a triangle with length x and height z. So, this forms a circular cone opening as you increase in y or decrease in y. This figure is the (double) cone of equation x 2 = y 2 − z 2. The gray plane is the plane ( x, y). You can see that it is a cone noting that for any y = a ... WebJun 5, 2024 · A circle can be represented as; Where h and k are the centers of the circle and r is the radius of the circle. The given equation of the circle is; Here the center of the circle h = 0 and k = 0 so the circle passes … WebMay 13, 2024 · An ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called focus adds up to a constant. It is taken from the cone by cutting it at an angle. It is given that: The ellipse equation: x²/9 + y²/16 = 1. We can write the above equation as follows: x²/3² + y²/4² = 1. devils garden campground utah
