Which shows the pre-image od quadrilateral w'x'y'z' before the figure was rotated according to the rule (x, y) -> (-x,-y)?

The pre-image of the quadrilateral is attached.

Step-by-step explanation:

Each point (x, y) is rotated with the rule (x, y) -> (-x, -y).

So, point W'(2, 3) was W(-2, -3) before rotation.

X'(6, 3) was X(-6, -3)

Y'(6, 4) was Y(-6, -4).

Z'(3, 5) was Z(-3, -5).

The pre-image of the quadrilateral is attached.

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

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
