Consider the following parametric equations.

a. eliminate the parameter to obtain an equation in x and y.

b. describe the curve and indicate the positive orientation.

x equals (t plus 2 )squaredx=(t+2)2, y equals t plus 9y=t+9; negative 10 less than or equals t less than or equals 10−10≤t≤10 .

a. eliminate the parameter to obtain an equation in x and y. yequals=startroot x endroot plus 7x+7

b. describe the curve and indicate the positive orientation. a parabolaparabola opening rightwardrightward with a vertex at (0 comma 7 )(0,7) starting at nothing and ending at nothing. (type ordered pairs. simplify your answers.)
