Answer:
x > 4.5
Step-by-step explanation:
Given the inequality :
14.4x - 28.2 > 36.6
Collect like terms
14.4x > 36.6 + 28.2
14.4x > 64.8
Divide both sides by 14.4
x > 64.8 / 14.4
x > 4.5
Answer:
DNE
Step-by-step explanation:
Given that two particles travel along the space curves

To find the points of intersection:
At points of intersection both coordinates should be equal.
i.e. r1 =r2
Equate corresponding coordinates

I equation gives t =-1
Substitute in II equation to get 
i.e. t cannot be real
Hence no point of intersection
