5.4a+8.2=9.8a-2.8  subtract 9.8a from both sides

-4.4a+8.2=-2.8  subtract 8.2 from both sides

-4.4a=-11  divide both sides by 4.4

a=11/4.4

a=2.5
...

6(m-2)=12  perform indicated operations on left side...

6m-12=12  add 12 to both sides

6m=24 divide both sides by 6

m=4

...

6-m=5m+30  subtract 5m from both sides

6-6m=30  subtract 6 from both sides

-6m=24  divide both sides by -6

m=-4

1. Change x = 4t into x = 3t

4t\cdot\frac{3}{4}=3t so

y=(\frac{3}{4}t)^2-1=\frac{9}{16}t^2-1

Answer A and D are wrong.

2. Change x = 4t into x = 2t

4t\cdot\frac{1}{2}=2t and

y=(\frac{1}{2}t)^2-1=\frac{t^2}{4}-1

Answer b is correct.

3.  Change x = 4t into x = 8t

4t\cdot2=8t and

y=(2t)^2-1=4t^2-1

Answer C. is correct, E. is wrong.
