A segment has an endpoint at (1,−2). The midpoint is at (−4,−2). What are the coordinates of the other endpoint?

Answer:

The other midpoint is located at coordinates (-9,-2) (Second option)

Step-by-step explanation:

<u>Midpoints</u>

If P(a,b) and Q(c,d) are points in $\mathbb{R} ^2$ , the midpoint between them is the point exactly in the center of the line that joins P and Q. Its coordinates are given by

$\displaystyle x_m=\frac{a+c}{2}$

$\displaystyle y_m=\frac{b+d}{2}$

We are given one endpoint at P(1,-2) and the midpoint at M(-4,-2). The other endpoint must be at an equal distance from the midpoint as it is from P. We can see both given points have the same value of y=-2. This simplifies the calculations because we only need to deal with the x-coordinate.

The x-distance from P to M is 1-(-4)=5 units. This means the other endpoint must be 5 units to the left of M:

x (other endpoint)= - 4 - 5 = - 9

So the other midpoint is located at (-9,-2) (Second option)

Jayden and Chandra are cleaning the house. It has 12 rooms, and each room is about the same size. When Jayden cleans by himself,

madam [21]

We know that

Jayden cleans 12 rooms in---------------> <span>6 hours
X rooms-------------------------------------> 4 hours
X=4*12/6--------> 48/6---------> 8 rooms
that means </span>Jayden cleans in 4 hours 8 rooms

Chandra cleans 12 rooms in---------------> 12 hours
X rooms-------------------------------------> 4 hours
X=4*12/12--------> 48/12---------> 4 rooms
that means Chandra cleans in 4 hours 4 rooms

the answer is
<span>Jayden = 8 blankrooms
</span><span>Chandra = 4 blankrooms</span>
