Use structure point B has(-4,-2). The x-coordinate of point A is 5. The distance between point A and point B is 15 units. a. What are the possible coordinates of point A? b.Find the possible coordinates of point A if point B were moved to (-7,-2)

a. The coordinates of A can be either or .

b. The coordinate of A would now be either or .

Step-by-step explanation:

Given the horizontal distance and vertical distance between two points, the distance between them would be .

a.

The horizontal distance between point A and point B is .

The vertical distance between these two points is unknown. It can be find using the distance formula.

.

Square both sides:

.

.

In other words, the vertical distance between A and B is .

In case that A is above B, the -coordinate of A would be . The -coordinates of A is 5. Hence, the coordinates of A would be .In case that A is below B, the -coordinate of A would be . The -coordinates of A is 5. Hence, the coordinates of A would be .b.

The horizontal distance between point A and point B is .

The vertical distance between these two points is unknown. It can be find using the distance formula.

.

Square both sides:

.

.

In other words, the vertical distance between A and B is .

In case that A is above B, the -coordinate of A would be . The The -coordinates of A is 5. Hence, the coordinates of A would be .In case that A is below B, the -coordinate of A would be . The -coordinates of A is 5. Hence, the coordinates of A would be .

the domain is the numbers you can use for x

x is how many papers you can buy

you can't buy negative papers

but the store only has 5 papers so the answer is all inegers from 1 to 5 including 1 and 5

integes are like -3,-2,-1,0,,2,3,4, but since we have 1 to 5 we have 1,2,3,4,5

it isn't all real numbers from 1 to 5 because you can't buy 3.141592 reams of paper

answer is first one
