Course 1: CA > Chapter 7: Writing Equations in Two Variables > Section Exercises 7.4 > Exercise 12 Write and graph an equation in two variables that shows the relationship between the time t and the distance d traveled.
Moves 2 meters
every 3 hours.

d=

step-by-step explanation:

i dont get

ian gonna lie that is way to much

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

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)
