Find the equation of the parabola with vertex (-4,5) and passing through the
point (-3.1).

y==-4x^2-32x-59

Step-by-step explanation:

first,you can move the zetopoint from (0,0) to (-4,5)

then in new coordinate system, point (x,y) transform into point (x',y')

x'=x+4;

y'=y-5;

point (-3,1) transform into point (1,-4)

y'=-4(x')^2

y-5-4（x+4）^2

y=-4（x+4）^2+5

y==-4x^2-32x-59

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
