Here,
The midpoint of segment QR is M
<u>m</u><u>(</u><u>-2</u><u>,</u><u>9</u><u>)</u> x3=-2,y3=9
<u>Q</u><u>=</u><u>(</u><u>-8</u><u>,</u><u>1</u><u>2</u><u>)</u>x1=-8,y1=12
R=x2,y2
we know that,
⠀
So,
x3=
⠀
⠀
⠀
⠀
⠀
x2=4
now we find the y coordinate y2.
y3=
⠀
⠀
⠀
⠀
⠀
y2=6
<em>Now</em><em> </em><em>we</em><em> </em><em>get</em><em> </em><em>the</em><em> </em><em>two</em><em> </em><em>coordinate</em><em> </em><em>of</em><em> </em><em>R</em>
<em>so</em><em>,</em>
R=(x2,y2)=(4,6)

Step-by-step explanation:
4x² + 8x − 7 = 0
4x² + 8x = 7
x² + 2x = 7/4
x² + 2x + 1 = 11/4
(x + 1)² = 11/4
x + 1 = ±√(11/4)
x = -1 ± √(11/4)
Answer:
3 seconds.
Step-by-step explanation:
So if a number is 5 or greater you round up but if the number is 4 or less you round down so the number 6 is above five so you would round the 6 to 10 therefore making it 7.8 instead of 7.76
