Use a geometric representation to determine the difference of the complex numbers.

z1 = - 2 - 6i

z2 = 5 + 9i

z = -7 + 15 i
z = 7 - 15 i
z = -7 - 15 i
z = 7 + 15 i

If sec theta = 5/3 and the terminal point determined by theta is in quadrant 4, then

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.

Awasher and a dryer cost $701 combined. the washer costs $51 more than the dryer. what is the cost of the dryer?
