Solve each system BY LINEAR COMBINATION/Elimination

(refer to the examples provided in today's notes).

#1) x + 10y = -7

-x +6y = -9

#2) -9x + 3y = -3

-x - 6y = -13

Acylinder with a base diameter of x units has a volume of jxcubic units which statements about the cylinder are true? check all that apply. the radius of the cylinder is 2 x units. the radius of the cylinder is 2x units. the area of the cylinder's base is 200 square units. the area of the cylinder's base is a square units. the height of the cylinder is 2x units. the height of the cylinder is 4x units. mark this and return save and exit next submit
