Answer:

Option D. 20 < x < 60 or x is from 20 to 60

Step-by-step explanation:

When a function is graphed, x coordinates of the points on graph show "domain" and y coordinates of the points  represent "range"

In the graph attached domain of the function will lie from 20 to 60.

It can be shown in the form of

20 < x < 60 or (20,60)

which is the interval form of domain.

Therefore, option D is the answer.

Can someone give me the answer and solution plz
Masteriza [31]

Answer: May.

Step-by-step explanation:

The chart has its highest rabbit population at January and October, so it would not be either of those because it is asking for the smallest, checking the red line and the numbers next to it, may would have the absolute smallest population around 450.

Match each term with the appropriate example
brilliants [131]

Answer:

1.   Absolute value :  d.  | - 7| = 7

2.  All real numbers :  b.  3x = 3x

3.  x = -5  : c.  5x = -25

4.  No solution : a.  |2x| = -10

5.  Adding the opposite to both sides of the equation. : e.  Canceling

Step-by-step explanation:

1.   Absolute value :  d.  | - 7| = 7

The absolute value is considered the distance to 0... so if there's a negative sign in the value, the negative sign disappears.

2.  All real numbers :  b.  3x = 3x

If we divide both sides by 3, we have x = x, which will always be true.

3.  x = -5  : c.  5x = -25

If we multiply each side by 5, we have 5(x) = 5(-5) thus 5x = -25

4.  No solution : a.  |2x| = -10

The result of an absolute value cannot be a negative number.  So, that has no solution since there's no value of x that would make this true.

5.  Adding the opposite to both sides of the equation. : e.  Canceling

If you have for example (x = -5) and you add 5 on both sides, you cancel the value on the right side... (becomes x + 5 = 0).
