Choose the two equations you would use to solve the absolute value equation below. then solve the two equations. |x – 7| = 12 a. x + 7 = –12 and x + 7 = 12; {–19, 5} b. x + 7 = –12 and x + 7 = 12; {–19, 19} c. x – 7 = 12 and x – 7 = –12; {19, –5} d. x – 7 = 12 and x – 7 = –12; {–19, 19}

A. x + 7 and x + 7 = 12{–19, 5}

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
