Answer:58
Step-by-step explanation:
<span>8y−5x=11
8y = 5x + 11
y = 5/8x + 11/8 has slope = 5/8
</span><span>a line that is perpendicular to the line, slope is opposite and reciprocal so slope = - 8/5
answer
slope = -8/5</span>
Answer:
option D.
Step-by-step explanation:
given,
5 married couples and we have to form the committee of 3 people such that no married couple comes together in the committee.
total number of people present = 5 × 2 = 10 people
selecting 3 people randomly = ¹⁰C₃ = 120 ways
number of ways of selecting couple = ¹⁰C₁× ⁴C₁
= 40 ways
so, ways to select committee which does not include married couple =
= 120 - 40 = 80 ways
so, the correct answer is option D.
