Asurveyor finds that the cross-section of the bottom of a
circular pond has the shape of a parabola. the pond is 24 feet
in diameter. the middle of the pond is the deepest part at
8 feet deep. at a point 2 feet from the shore the water is 3 feet
deep. how deep is the pond at a point 6 feet from the shore?

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
