Maurinko [17]3 years ago
5 0

Step-by-step explanation:

Hey there!

Given;

Midpoint is (-1,3) and one endppint is; A(4,-1).

Let the coordinates of C be (x,y).

<u>Use</u><u> </u><u>the</u><u> </u><u>midpoint</u><u> </u><u>formula</u><u>.</u>

<u>(x,y) = ( \frac{x1 + x2}{2} ,\frac{y1 + y2}{2} )</u>

<u>Put</u><u> </u><u>all values</u><u>. </u>

<u>( - 1,3) =  (\frac{4 + x}{2} ,\frac{ - 1 + y}{2} )</u>

Since, they are equal, equating with their corresponding elements we get,

- 1 =  \frac{4 + x}{2}

<u>Simplify</u><u> </u><u>it</u><u>. </u>

<u>- 2 = 4 + x</u>

<u>x =  - 6</u>

<u>Again</u><u>,</u>

<u>3 =  \frac{ - 1 + y}{2}</u>

<u>Simplify</u><u> </u><u>it</u><u>. </u>

<u>6 =  - 1 + y</u>

<u>y = 7</u>

<u>Therefore the</u><u> </u><u>another</u><u> </u><u>endpoint is</u><u> </u><u>C</u><u>(</u><u>-6</u><u>,</u><u>7</u><u>)</u><u>.</u>

<em><u>Hope it helps</u></em><em><u>.</u></em><em><u>.</u></em><em><u>.</u></em>

-25 = -4r + 5 please help
Andrej [43]
-25=-4r+5
Subtract 5 to each side
-25-5=-4r+5-5
-30=-4r
Divided -4 to each side
-30/-4=-4r/-4
7.5=r
Check:
-25=-4r+5
Substitute r with 7.5
-25=-4(7.5)+5
-25=-30+5
-25=-25. As a result, r=7.5. Hope it help!
