If M is the set of all square of integers that are less than 100 and N is the set of all positive odd numbers that are under 15,

ollegr [7]

A set is simply the group of numbers.

<em>The set of M and N are: </em> $M = \{1,4,9,16,25,36,49,64,81\}$ <em> and </em> $N= \{1,3,5,7,9,11,13\}$ <em>.</em>
<em>The set of M n N is: </em> $M\ n\ N = \{1,9\}$ <em>.</em>
<em>The set of M u N is: </em> $M\ u\ N = \{1,3,4,5,7,9,11,13,16,25,36,49,64,81\}$ <em />

<u>(a) The set of M and N</u>

Given that:

M = squares of integers less than 100

N = Positive odd numbers less than 15

So, we have:

$M = \{1,4,9,16,25,36,49,64,81\}$

$N= \{1,3,5,7,9,11,13\}$

<u>(b) M n N and M u N</u>

M n N is the set of common elements between sets M and N.

So, we have:

$M\ n\ N = \{1,9\}$

M u N is the set of all elements in sets M and N.

So, we have:

$M\ u\ N = \{1,3,4,5,7,9,11,13,16,25,36,49,64,81\}$

the equation 7x - 3y = 42 relates to x and y. find three pairs of points (x,y) that make the equation true.

Sloan [31]

If it doesn't matter whether the points are integers or not you can just pick a number for either y or x and solve for the other variable. For example, if you pick 3 to be your x, plug it in and then solve for y. Start out with: $7x-3y=42$ Plug in 3 for x: $7(3)-3y=42$ . Then, $21-3y=42$ . Subtract 21 from both sides and then divide by -3 on both sides. You end up with y=-7 so one of your points is (3, -7)

How do I find the scale factor?

Gre4nikov [31]

Answer:To find a scale factor between two similar figures, find two corresponding sides and write the ratio of the two sides. If you begin with the smaller figure, your scale factor will be less than one. If you begin with the larger figure, your scale factor will be greater than one.
