Which equation is an equation of a circle with a radius of 2 and its center is at (4, -2)? (x - 4)² + (y + 2)² = 4 (x - 4)² + (y + 2)² = 2 (x + 4)² + (y - 2)² = 4

Step-by-step explanation:

A circle is the set of all points on a plane at a given distance (radius) from a given point (center). The general equation of a circle with center and radius is given by:

Therefore, replacing the data provided into the previous equation:

So, the equation of a circle with a radius of 2 and its center at (4,-2) is:

I attach you the graph.

answer: 180

step-by-step explanation:

12-2=10

20-2=18

10x18=180

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
