Donte simplified the expression below. 4(1+3i) - (8-5i) 4 + 3i - 8 + 5i
-4 + 8i
What mistake did donte make?

7. if the value of x varies directly with the value of y, and x = 3 when y = 21. what is the valu y, and x = 3 when y = 21. what is the value of x when y = 105?

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.

If a line is defined by the equation y = 5x + 2, what is the slope?
