Answers:  perpendicular bisector;  image

  • The reflection of a point P across a line m is the point P' if line m is the <u>   perpendicular bisector    </u> of segment PP'
  • Point P' is called the <u>     image    </u> of point P.

=============================================================

Explanation:

If we were to reflect point P over line m to land on P', then we've gone from pre-image to image.

Let's say that Q is the point on segment PP' and it's also on line m. We consider Q the midpoint of segment PP' which means PQ and P'Q are the same length. This indicates P and P' are the same distance away from the mirror line, and that point Q bisects segment PP'. Also, line m is perpendicular to segment PP'. So that's where the "perpendicular bisector" comes from.

1.Give one number that makes the inequality x + 7 &gt; 20 true
nata0808 [166]
1. Any number above 13 works. Why? Because 20-7=13, and to be greater than 20, you must add a number larger than 13.

Examples: 14+7 > 20, 30+7 > 20, 100+7 > 20

2. Any number below 25/3 (which is also 8.3 with a repeating 3) works. Why? Because 25/3=8.3 with a repeating 3, and to remain less than 25, you must multiply by a number less than 8.3 with a repeating 3.

Examples: 3(8) < 25, 3(5) < 25, 3(0) < 25

3. 4 buses. 1 bus will hold 60 students, 2 will hold 120, 3 will hold 180, and 4 will hold 240. The question is trying to trick you into putting now 3.3333333333... buses because that's what 200/60 is, but there is no such thing as a third of a bus. So you need at least 4 buses. (There will be an extra 40 spaces for passengers on the 4th bus, but that is okay.)

To find this answer I did 200/60 and got 3.3 with a repeating 3. You must round to the higher whole number. Rounding down to 3 buses leaves you with 20 students without a bus.

4. 19 boxes. 18 boxes will only hold 288 candies. The question is trying to trick you into putting down 18.75 boxes because that's what 300/16 is, but there is no such thing as 75% of a box. So you need at least 19 boxes. (There will be an extra 4 spaces for candies in the 19th box, but that is okay.)

To find this answer I did 300/16 and got 18.75. You must round to the higher whole <span>number. Rounding down to 18 boxes leaves you with 12 candies without a box.</span>

What is the domain of the square root function graphed below?
melisa1 [442]
You can see that the function is graphed for every number x that is greater than or equal to zero.

So we write that the domain is x \leq 0.

Answer:

A.1/3

Step-by-step explanation:

 1  Pick two points on the line and determine their coordinates.

   2 Determine the difference in y-coordinates of these two points (rise).

   3 Determine the difference in x-coordinates for these two points (run).

 4 Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
