Taven mixes 18 liters of 14% acid solution with a 35% acid solution, which results in 23% acid solution.
let x represent the number of liters of 35% solution used and let y represent the number of liters of mixture. which system of equations can be used to find the number of liters of 35% acid solution in the mixture

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
