Question

1. Eliminate 't' by substitution method.
i) at = x ; 2at = y
ii) bt² = x ; at³ = y
iii)at³-d = 0 ; bt² + c = 0
iv)x=√3 t ; y² = √5 t
v)vf = vi + at ; s = vit +1/2 at²​

Please solve this I will give you 50 points

Answer 1

Answer:

x=y/2

Step-by-step explanation:

In eq.1 at=x

bring a to the other t=x/a

substituting the value of t in eq.2 2at=y

2×a×x/a=y

cancelling a,we get

2x=y

x=y/2

Answer 2

Answer:

(I)at =x

a/x=t

2at=y

2a×a/x=y

2a²/x=y

(ii)bt²=X;

t²=X/b

t=√x/b

at³=y

a×√x/b×x/b=y

ax/b√x/b=y

(iii) bt²+c=0

t=-√c/b

a×(-√c/b)³-d=0

-ac/b√c/b-d=0
