parallel when a=2
perpendicular when a=-1/2
Answer:
15 days
Step-by-step explanation:
You have 5 cups of food, and you give him 1/3 a day.
So, <em>5 divided by 1/3</em>, which would get you 15 days. Or you could cross-multiply, meaning you multiply across, but in this case I just made them line up so you can see how to do it.
Answer: 5/4
Step-by-step explanation:
if two number have the same denominator, then the number with the greatest numerator is the greatest.
Basically if the bottom number of two fractions are the same, the bigger top number is the bigger number.
Answer:
so times five then add five then divide by 5 however in the end there gonna cancel each other out
Step-by-step explanation:
You don't need 3 equations to get a general solution. To do this use the equations x-3y-z=0 and -x+2y+0z= -3. Start out by letting z = t. Then solving those 2 equations simultaneously, your x's cancel out leaving you with -y-z=-3. But since z=t, then -y=-3+t or y=3-t. Now sub that in for y in the first equation, along with the fact that z=t to get x-3(3-t)-t = 0 and solve for x. x=9-2t. So a general solution for this would be (9-2t, 3-t, t)
