I would say that the "n"th term of the sequence is 41, as the pattern increases by 10 every term.

Answer: 31) d 32) c

<u>Step-by-step explanation:</u>

31)

A = {1, 3, 5, 15}

B = {2, 3, 5, 7}

A ∪ B = {1, 2, 3, 5, 7, 15}

C = {2, 4, 6, 8}

(A ∪ B) ∩ C = {1, 2, 3, 5, 7, 15} ∩ {2, 4, 6, 8} = {2}

<em>2 is the only number in both sets</em>

32)

The pattern is: reflection, add symbol, ..., reflection, add symbol.

The last image shown is: add symbol

So the next image will be: reflection (flipped to the left)

Calculate the number of hours between 4 PM and 10 AM:

4 PM to 4 AM is 12 hours.

4 AM to 10 AM is 6 hours

Total hours is 12 + 6 = 18 hours.

18 hours x 70 km/hr = 1,260 km total.

What’s this question

yKpoI14uk [10]

<h3>Hm ok, so the correct answer here would be (0,3) and heres why:</h3>

If the y would be equal to 0, everything would then just depend if you add or subtract the x:

$y-x=-3\\\\y+x=3\\\\y= 0\\x=3\\\\then:\\\\0-3=3\\and\\0+3=3$

Now the first answer could be correct for:

$y-x=-3\\because\ if\\\\y=-3 \ and \ x=0 \ then\\-3-0=-3$

However, this answer is not correct for the other equation. the same true for all the other answers except (0,3)
