Answer:
(-infinity, -2) ∪ (-2, infinity)
Step-by-step explanation:
I will have to assume that you meant
f(x)=(x-3)/(x+2). You must use parentheses to specify the order of operations in this problem.
x can take on any value except -2, at which the function is undefined.
Thus, the domain is (-infinity, -2) ∪ (-2, infinity)

When adding integers with the same sign, add the absolute values of the integers.
True or False?
Answer:
False. This only goes with integers that are both positive.
Step-by-step explanation:
For example, 7+6 is the same as |7|+|6|, which is, again, the same as 7+6.
However, when you add integers that are both negative, you're subtracting, and you'll always end up with a negative difference. Absolute values are always positive, which is why this doesn't work.
(-7)+(-6)
= -7-6
= -13
|-7|+|-6|
= 7+6
= 13

A 6-POUND BAG OF CANDY COSTS $11.28 WHAT IS THE COST PER POUND? 10
Answer:
$1.88
Step-by-step explanation:
11.28 / 6 = 1.88
Answer: $1.88
Step-by-step explanation:
We have 6 pounds of candy that cost 11.28, and we need to find the unit rate.
If we want to find the unit rate, or the cost per pound, we can use the equation 11.28 ÷ 6.
We can then divide each side by 6, or solve the equation.
11.28 ÷ 6 = 1.88.
Therefore, the each pound of candy costs $1.88.
The length of a boat is 10.8 metres. Boris buys a scale model of the boat. The scale of the model is 1/18 Work out the length of the scale model of the boat. Give answer in centimetres
Answer: 60 cm
Step-by-step explanation:
The actual length of the boat is 10.8 meters.
The scale model length is 1/18 of the actual boat.
Length of scale model will therefore be:
= 10.8 * 1/18
= 0.6 meters
A meter is 100 centimeters.
= 0.6 * 100
= 60 cm
What is the sum of the matrices shown below?
[4 19 -5]+[-8 7 0]=
[7 0 -14] [-1 17 6]
Answer:
-4 26 -5
6 17 -8
Step-by-step explanation:
The matrix addition is
First row: [-4 26 -5]
Second Row: [ 6 17 -8]
What is Matrix Addition?To add two or more matrices, the basic process is matrix addition. Matrix addition is only possible if the matrices are in the same order. By order, we mean that the matrices have the same number of rows and columns. As a result, we can add the matrices' appropriate elements. Matrix addition is not possible if the order is changed.
We will add the rows:
Addition of First row
4 + (-8) = 4- 8= -4
19 + 7 = 26
-5 + 0= -5
Addition of Second row
7 + (-1) = 7- 1= 6
0 + 17= 17
-14 + 6 = -8

which shapes have at least 1 right angle? Choose all that are correct.
Answer:
The Pink square, Green Rectangle, and the Orange figure
Step-by-step explanation:
The only one I'm not to sure about is the trapezoid, but you can rule out all the others because there is no right angle. Hope this helps!
The Pink square, Green Rectangle, and the Orange figure have at least 1 right angle.
What is rectangle?
In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle.
What is square?
A rectangle with four sides of equal length is a square.
What is right angle?
A right angle is an angle that is exactly equal to 90 degrees in measure.
According to question, we have to find which shapes have at least 1 right angle.
In the given figure, we can see that the pink square, green Rectangle, and the orange figure have at least 1 right angle or have [tex]90[/tex] degree in them.
Hence, we can conclude that the Pink square, Green Rectangle, and the Orange figure have at least 1 right angle.

Sophie found the volume of the figure below by using the steps shown.
A rectangular prism with a length of 28 millimeters, width of 21 millimeters, and height of 4 millimeters. A rectangular pyramid with a base of 28 millimeters by 21 millimeters and height of 26 millimeters.
Total Volume = B h + one-third B h = 4 (21) (28) + one-third (21) (28) (30) = 2,352 + 5,880 = 8,232 cubic millimeters.
What mistake, if any, did Sophie make?
Sophie determined the volume correctly.
Sophie used the wrong formula for the total volume.
Sophie used the wrong height for the pyramid.
Sophie did not apply the order of operatio
Answer:
(C) Sophie used the wrong height for the pyramid.
Step-by-step explanation:
she should have subtracted 4 from 30 because that was apart of the prism
The total volume is 7448 cubic millimeters. Sophie has made mistake in copying height of pyramid.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Given that, a rectangular prism with a length of 28 millimeters, width of 21 millimeters, and height of 4 millimeters.
Volume of rectangular prism = Length×Width×Height
= 28×21×4
= 2352 cubic millimeters
A rectangular pyramid with a base of 28 millimeters by 21 millimeters and height of 26 millimeters.
Volume of a rectangular pyramid = (lwh)/3
= (28×21×26)/3
= 15288/3
= 5096 cubic millimeters
Total volume = 2352+5096
= 7448 cubic millimeters
Hence, Sophie has made mistake in copying height of pyramid.
