Match the steps to find the equation of the parabola with focus (-1, -8.75) and directrix y=- 9.25. Find the distance from the focus to
1.
(x+1)+ y +875 ) =( y+9.25 )?
x2 + 2x+1=2y +9
the point on the parabola.
2.
X+1 + y +8.75
Choose a point on the parabola.
Find the distance from the point on

y =
X+X
Square both sides and simplify.

5.
y +9.25
Write the equation of the parabola.
Set the distance from focus to the
6.
y +9.25
point equal to the distance from directrix

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

31 v bucks

step-by-step explanation:

since you bought 25 on friday and 6 on tuesday, you can just add them up.

25+6=31

check your work.

31-6=25

i hope this !
