Question

Find a direct relationship between x and y.

x = 64t2 and y = t + 2
a. x = 64y2 - 256y +256
b. x = 64y2 + 256y + 256
c. y = 8x + 2
d. y = 64x2 + 2

Answer 1

\[\Large\rm y=t+2\]Subtracting 2 from each side will give us t in terms of y,\[\Large\rm \color{orangered}{y-2=t}\]


Do you see how we can use that information in this equation?\[\Large\rm x=64(\color{orangered}{t})^2\]
