One number is twice another number. if the 12 is subtracted from the larger number the result is 7 more than the smaller number. find the numbers.

Graph the equation by plotting point x=2

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

Amodel rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y = -0.04x^2 + 8.6x + 4.8, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. how far horizontally from its starting point will the rocket land? a. 0.56 m b. 215.56 m c. 431.11 m d. 215.74 m
