Answer:
196608
Step-by-step explanation:
3, -12, 48, -192, ... is a geometric sequence with first term 3 and common ratio -4. Note that (-12)(-4) = 48, that (48)(-4) = -192, and so on. The general formula for a geom. seq. is a(n) = a(1)r^(n-1), where a(1) is the first term and r is the common ratio. In this particular case, we have
a(n) = 3*(-4)^(9-1) = 3*(-4)^8 = 3(65536) = 196608

Answer:
-6/5
Step-by-step explanation:
Get y by itself to get the slope. So 18x+15y=90. Move 18x to the other side of the equation. Now you have 15y=-18x+90. Divide both sides by 15 to get y by itself. Now it's y= -18/15x + 6. Reduce -18/15 to the simplest fraction. You have y= -6/5x+6. Any number can replace the 6 in the equation to give you a parallel line...it's the slope that makes it parallel, not the y intercept. So y= -6/5x+10 or y=- -6/5x-1 would satisfy your parallel slope equation.
