can someone find the domain and range in this graph i’m having trouble
To find the domain of graph, we notice at the point on the left and the right.
Domain is the set of all x-values, so we perceive in a horizontal line or x-axis.
The first point on left is at x = -1 and the second point on the right is at x = 1.
Since the points are opened and therefore, the Inequality signs can only be > or <.
Therefore, the domain is -1 < x < 1
To find the range, similar to domain but we perceive vertical line or y-axis. Range is the set of all y-values.
We notice that the minimum point is -1 or y = - 1 and maximum point at 1 or y = 1.
Therefore, the range is -1 < y < 1

drove on Monday. Write an expression that represents the total number of miles Dave drove on
both days?
Answer:
2m = 112
Step-by-step explanation:
monday = m
Tuesday = m - 112
therefore total = m + (m -112)

If four points represent the vertices of a polygon. And the four side lengths are equal, then the polygon must be a square
The given polygon can be rhombus or square.
Polygon is a two-dimensional closed figure made of straight lines.
There are two polygons with four vertices and four equal sides:
Rhombus:
Four verticesFour equal side lengthsOpposites sides are parallelUnequal diagonalsOpposites angles are equalDiagonals bisect each other at a 90-degree angle.Square:
Four verticesFour equal side lengthsOpposites sides are parallelEqual diagonalsAll angles are equal to a 90-degreeDiagonals bisect each other at a 90-degree angleGiven:
A polygon with four points representing vertices and four equal lengths
To Find:
Whether given polygon is square or not
Solution:
According to the question polygon given has four vertices and four equal side lengths.
There are two different polygons with four vertices and four equal side lengths, rhombus, and square.
In the question, we are only given vertices and the side lengths of the polygon which simply indicates that the given polygon can be either rhombus or square. But in order to prove the polygon as square, we will need more information regarding the stated polygon.
So from this, we can conclude that the given polygon can be rhombus or square.

For each ordered pair in the table, how does the second number compare to the first number... can yall tell me I need to turn it in Tomorrow!!??
Answer:
The first number in each ordered pair tells how far across the X line is to move. The second number in each ordered pair tells how far up or down the Y line is to move. The point where the X and Y lines cross is marked “0” on the graph. It is called the “origin,” and is the starting point for plotting points.

Consider the given line segment. If AC is 39cm long, answer the following questions:
A
B
9x+7
-3x+20
AB -
BC =
Is point B the midpoint? (yes or no)
The point which is equidistant from the endpoints of a line segment, hence, marking the middle point of the line is called the midpoint. Therefore, Point B is not the midpoint
AB + BC = AC
9x + 7 + (-3x + 20) = 39
9x + 7 - 3x + 20 = 39
6x + 27 = 39
6x = 39 - 27
6x = 12
x = 12 / 6
x = 2
9x + 7 = - 3x + 20
9(2) + 7 = - 3(2) + 20
25 = 15
Hence,
Since, AB ≠ BC, then B is not the midpoint

(Screen shot question number 2 "How many laps can he swim in 6 minutes?")
3.40 and 15
Step-by-step explanation:
3 for 1.50 means 1 is 50 cents each.
5 oranges for 3 dollars mean each one is 60 cents.

If the diameter of a sphere is halved , What effect does this have on its volume & its surfaces area ?
Answers:
The new volume is 1/8 of the old volume
The new surface area is 1/4 of the old surface area
======================================================
Explanation:
Volume:
Let's say the diameter is d = 60
That would make the radius r = d/2 = 60/2 = 30
The volume of the sphere is
V = (4/3)pi*r^3
V = (4/3)*pi*(30)^3
V = (4/3)*(30)^3*pi
V = 36000*pi
Now consider that d = 30 which is half of the original diameter.
So r = d/2 = 30/2 = 15
And also,
V = (4/3)pi*r^3
V = (4/3)*pi*(15)^3
V = (4/3)*(15)^3*pi
V = 4500*pi
The old volume was 36000pi and the new volume is 4500pi
Comparing the two volumes, we see that the reduction factor is
(new volume)/(old volume) = (4500pi)/(36000pi) = 1/8
The new volume is 1/8 of the old volume
smaller volume = (1/8)*(larger volume)
This is equivalent to saying the larger volume is 8 times that of the smaller volume.
------------------------------------------------------
Surface Area:
We'll use the same d and r values from earlier.
The diameter d = 60 leads to r = 30. We'll use this to find the surface area
SA = 4pi*r^2
SA = 4*pi*30^2
SA = 3600pi
For the smaller sphere (d = 30 and r = 15), we have
SA = 4pi*r^2
SA = 4*pi*15^2
SA = 900pi
The reduction factor is (900pi)/(3600pi) = 1/4
The smaller sphere has its surface area 1/4 that of the larger sphere.
smaller surface area= (1/4)*(larger surface area)
This is equivalent to saying the larger surface area is 4 times that of the smaller surface area.
