Which of the following relations has a domain of {−5, 0, 5}? {(−5, 0), (0, 5), (1, 0)} {(−5, 5), (0, 5), (5, 5)} {(0, −5), (0, 0
andreev551 [17]
Answer:
It's so easy. Domain is the set made up of the first elements of each ordered pair (x, y).
Look at the second relation {(-5, 5), (0, 5), (5, 5)}. It has three ordered pairs which arw (-5, 5), (0, 5) and (5, 5).
First element of the first ordered pair (-5, 5) is -5. First element of the second ordered pair (0, 5) is 0. First element of the third ordered pair (5, 5) is 5.
So, the set made up of the first elements of the ordered pairs is {-5, 0, 5} and hence it is the domain.

Step-by-step explanation:
since packages are similarsimilar packages. The ratio of the volumes is 8:125. Determine the dimensions of the bigger package. The dimensions of the smaller package are... Height= 45cm, Length= 80cm, and Width= 25cm.
Length of bigger package = <em><u>8</u></em><em><u>0</u></em><em><u>×</u></em><em><u>1</u></em><em><u>2</u></em><em><u>5</u></em><em><u>/</u></em><em><u>8</u></em><em><u>=</u></em><em><u>1</u></em><em><u>2</u></em><em><u>5</u></em><em><u>0</u></em><em><u>c</u></em><em><u>m</u></em>
Width of bigger package =<em><u>2</u></em><em><u>5</u></em><em><u>×</u></em><em><u>1</u></em><em><u>2</u></em><em><u>5</u></em><em><u>/</u></em><em><u>8</u></em><em><u>=</u></em><em><u>3</u></em><em><u>9</u></em><em><u>0</u></em><em><u>.</u></em><em><u>6</u></em><em><u>2</u></em><em><u>5</u></em><em><u>c</u></em><em><u>m</u></em>
Height of bigger package =<em><u>4</u></em><em><u>5</u></em><em><u>×</u></em><em><u>1</u></em><em><u>2</u></em><em><u>5</u></em><em><u>/</u></em><em><u>8</u></em><em><u>=</u></em><em><u>7</u></em><em><u>0</u></em><em><u>3</u></em><em><u>.</u></em><em><u>1</u></em><em><u>2</u></em><em><u>5</u></em><em><u>cm</u></em>
Y=-9x+4
-9x represents the slope . 4 is the initial value/y-intercept
Answer:
im pretty sure its the 2nd or 3rd one
