Answer:
r = 105
Step-by-step explanation:
Given quadratic equation:
x² − 9x − 6
Quadratic formula is given by:
(-b ± √b² - 4ac) ÷ 2a
For the equation: x² - 9x - 6
a = 1, b = -9 and c = -6
Substitute in the quadratic formula:
(-b ± √b² - 4ac) ÷ 2a
(-(-9) ± √(-9)² - 4(1*-6)) ÷ 2*1
= 9 ± √105 / 2
The solution of x² − 9x − 6 is expressed as 9 plus or minus the square root of r, all over 2
Therefore, the value of r is 105

Answer: D
Step-by-step explanation:
<u><em>When a coordinate is reflected over the y-axis, it changes from (x, y) to (-x, y)</em></u>
<em>The three coordinates of ΔCDE are</em>
- C = (-8, -1)
- D = (-6, -5)
- E = (-2, -4)
<em>After the y-axis reflection, they'll become:</em>
- C' = (-(-8), -1) = (8, -1)
- D' = (-(-6), -5) = (6, -5)
- E' = (-(-2), -4) = (2, -4)
<em>I hope this is correct :\</em>
