Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations. 3x - 4y - 5z = -27 2x - y + 3z = 9 x - 4y - 2z = 1

The radical equation 2+√2x-3 = √x+7 has a solution set [x= a0} and an extraneous root x = a1.

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

Someone answer asap for ! a ball is rolled down a ramp. the height, f(x), in meters, of the ball x seconds after it is released is modeled by the function f(x) = x²- 10x + 25 for all values of x from 0 to 5. which statement about the ball is true? a. the maximum height of the ball is 5 meters b. the height of the ball increases from 0 to 5 meters above the ground. c. the ball has traveled 5 meters when it reaches the bottom of the ramp. d. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp
