What are integers?
Please give your best explanation and a simple example (worth 20 points)
Integer is a subset of Real Number. It can be broken into these following:
Positive IntegerZeroNegative IntegerInteger can be any whole numbers. Keep in mind that Integers cannot be fractions, decimal, approximate value, etc. Integers can only be something like 1,2,3,-1,-2,0.
Integers are like Natural or Counting Numbers except they have 0 and negative numbers.
Positive IntegerPositive Integers are basically a natural or counting number. It starts from 1 to any positive countable infinity. Here is the example of positive integer: 1,2,3,4,5,6,7,...
ZeroZero is just a number 0. It is between the negative and positive. 0 is neither positive or negative but it is categorized as Zero.
Negative IntegersNegative Integers are opposite of Positive Integers. The opposite of plus is minus and the opposite of minus is plus. Negative Integers are less than both 0 and Positive Integers. Here is the example: -1,-2,-3,-4,-5,...
Integers are whole numbers with a positive or negative counterparts.
If that doesn't make sense let me make some examples
-4, 100, 9300 would be integers. Using my definition they all have negative or positive counterparts.
-2.3, 7.8888(etc.) 2/3 would not be integers. Even though -2.3 and 7.8888(etc.) have negative/ positive counterparts they are not whole numbers.
Hope that helped!
use the graph to estimate the solution to the system of equations shown.
A. x=5 1/2, y= 3 1/4
B. x= -3 1/2, y= -5 1/4
C. ×= 3 1/2, y= 5 1/4
D. x= -5 1/2, y= -3 1/4
==============================================================
Explanation:
The solution occurs where the two lines intersect. From this intersection point, draw a vertical line upward until you reach the x axis. We arrive somewhere between -5 and -6. A good estimate is to say that we're at the midpoint, so x = -5 & 1/2 is one possible estimate
Since only choice D has this x value, this must mean choice D is the answer. The y coordinate of y = -3 & 1/4 seems to fit as well since we can draw a horizontal line from the point of intersection to the y axis, and arrive somewhere just a little below -3.

Weekday Weekend Had an ice cream cone 232323 454545 Did not have an ice cream cone 155155155 666 Weekday Weekend Had an ice cream cone Did not have an ice cream cone Column total 1.001.001, point, 00 1.001.001, point, 00
Answer:
Answers below
Step-by-step explanation:
0.13 0.88
0.87 0.12
Hope this helps!
The two-way column relative frequency table is,
Weekday Weekend
Had an ice cream cone 0.29 0.88
Did not have an ice - 0.87 0.11
cream cone
Total 1.00 1.00
What is two-way frequency table?"It is a way to display frequencies for two categorical variables."
"One category is represented by rows and a second category is represented by columns."
Now, We need to find the column relative frequency table.
First we find the total of each column.
Weekday Weekend
Had an ice cream cone 23 45
Did not have an ice - 155 6
cream cone
Total 178 51
Now, divide each element of column by its respective total.
Weekday Weekend
Had an ice cream cone 23/178 45/51
Did not have an ice - 155/178 6/51
cream cone
Total 178/178 51/51
Therefore, the two-way column relative frequency table would be,
Weekday Weekend
Had an ice cream cone 0.29 0.88
Did not have an ice - 0.87 0.11
cream cone
Total 1.00 1.00

The equation of line g is y = 6/7x +3/5. Line h is perpendicular to line g. what is the slope of line h?
Answer:
The slope of line H is -7/6
Answer:
Step-by-step explanation:
To be perpendicular m1(m2)=-1
The original line has a slope of 6/7 so the perpendicular line will have slope of
6m/7=-1

The sales tax in one state is 3%. Write a function rule for finding the total cost of an item with selling price x. Then find the total cost of a CD player with a selling price of $150.
f(x) = x – 3; $148.97
f(x) = 3 + x; $151.03
f(x) = 0.03x; $4.50
f(x) = 1.03x; $154.50
Answer: brainly.... D. f(x) = 1.03x; $154.50
ok so the cd player cost
$150 the sales taxs is 7% so you do
7% of 150= $10.50
so you add
$150+$10.50= $160.50
so the total cost is $160.50

Solve:
-4 + x = 6
A)-24
B)-10
C)-2
D)10
Answer:
x = 10 so D
Step-by-step explanation:
-4 + x = 6
add 4 both sides to get the x by itself
so 4 + 6 = 10
then the final answer is x = 10
Answer:
You have a negative 4 being added to the variable. To solve you need to use the opposite operation (what is the opposite of addition?)
For example:
7 = -3 + h
Subtraction -3 from each side.
7 -(-3) = -3- (-3) + h

what is 153.87 divided by 23
The result of dividing 153.87 by 23 is approximately 6.6847826087.
Given that we need to determine that what is 153.87 divided by 23,
To justify this answer, we can perform the division calculation:
6.6847826087
--------------
23 | 153.87
138
-----
158
138
-----
208
207
-----
10
The division is performed by dividing 23 into 153.87. We start by dividing 23 into 153, which gives us 6 as the whole number part of the quotient. We then subtract 138 (6 multiplied by 23) from 153, which leaves us with a remainder of 15.
To obtain a decimal approximation, we bring down the decimal point from the dividend (153.87) and continue the division process.
We add a zero after the decimal point in the dividend and divide again. This time, 23 goes into 158 (the new dividend) 6 times, giving us a partial quotient of 0.6.
The remainder is 158 minus 138 (6 multiplied by 23), which equals 20.
We bring down another zero and continue dividing.
23 goes into 208 (the new dividend) 9 times, resulting in a partial quotient of 0.69. The remainder is 208 minus 207 (9 multiplied by 23), which equals 1.
At this point, we can either stop or continue dividing to obtain more decimal places.
Therefore, the result of dividing 153.87 by 23 is approximately 6.6847826087.

Answer:
If you were solving the right triangle, it would be:
m∠A = 46°
m∠B = 44°
m∠C = 90°
AB = 32
BC ≈ 23
AC ≈ 24
Step-by-step explanation:
To solve this right triangle, you can use trigonometric ratios to solve for the sides. To find the angle measures:
m∠A = 46° (given)
m∠B = x
m∠C = 90° (given)
180 - (46 + 90) = x
180 - 136 = x
44 = x
m∠B = 44°
To find the side measures, you can use tangent, sine, cosine, and the Pythagorean Theorem.
Recall that:
tangent = opposite side/adjacent side
sine = opposite side/hypotenuse
cosine = adjacent side/hypotenuse
So:
sin46 = BC/32
BC = 32 (sin46)
BC ≈ 23
tan46 = BC/AC
AC = BC/tan46
AC = (23.01887361...) (tan46)
AC ≈ 24
