The variables x
x
and y
y
vary directly. use the values to find the constant of proportionality, k
k
. then write an equation that relates x
x
and y
y
. write any fractions in simplest form.

y=45; x=40
y=45; x=40

response - incorrect.

k=
k=
cno response given

y=
y=

if you was gonna solve for a, a is a   < -12

correct answer is c. just did it

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
