Collect Like Terms
Multiply both sides by -1
Reorder
<em>Hence, the number of students that do not participate in both is 325</em>
Answer:
d= (-11-2)^2 + (-12--12)^2
d= (-13)^2 + (0)^2
d=169
square root the 169
answer is 13
that's the distance from (2, -12) (-11, -12)
hope that helps

<u>Answer:</u>
- $2,800 = Principle + Interest
<u>Step-by-step explanation:</u>
Using PRT/100, let's find the interest.
- => 2,000 x 8 x 5/100
- => 20 x 8 x 5
- => $800
<u>Conclusion: </u>
Therefore, the interest plus principle is 2,000 + 800, which is $2,800.
Hoped this helped.
