The sum of the digits of a two-digit number is 9. if the digits are reversed, the new number is 27 more than the original number. find the original number.

Use the x-intercept method to find all real solutions of the equation. x^3-10x^2+27x-18=0

Simplify the expression 10/11(22z) + (a+5) -1

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.
