Each equation given below describes a parabola. Which statement best compares their graphs? X=2y^2 X=8y^2 A. Both parabolas open upward, and x=8y^2 is wider than x=2y^2.
B. Both parabolas open upwards, and x=2y^2 is wider than x=8y^2.
C. Both parabolas open to the right, and x=8y^2 is wider than x=2y^2.
D. Both parabolas open to the right, and x=2y^2 is wider than x=8y^2.

D)Both parabolas open to the right, and is wider than

Step-by-step explanation:

Standard equation of parabola :

If a < 0, then the parabola open downwards and if a > 0, then the parabola open upwards.

If a < 0, then the parabola open left and if a > 0, then the parabola opens right

Given equations : and

and

in both the equations a>0

So, Both parabolas are open to the right.

Refer the attached graph

---- Red

--- blue

So, is wider than

So, Option D is true

the answer

b. they are parallel and will never intersect.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
