A= {1, 2, 5, 7} b = {3, 4, 6, 7} c = {0, 5, 8, 9} find a∩b.

  {7}

Step-by-step explanation:

The only element that sets A and B have in common (their intersection) is the element 7. Thus ...

  A∩B = {7}

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
