>31

Step-by-step explanation: If you are trying to make a triangle, two sides have to be added together and have to equal more than the other side, It cannot be equal or less than so your answer might be

noncoplanar points are points that do not lie on the same line.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
