What numbers are shown
in set A?
A. Whole numbers
B. Counting numbers
C. Integers
Answer:
C. integers
Step-by-step explanation:
integers are similar to whole numbers : all numbers without any fractional part, but including negative numbers.
whole numbers only include positive numbers (incl. 0) without any fractional part.
natural numbers (I guess, that is the meaning of "counting numbers") are all positive numbers (but without 0) without any fractional part.
so, C is correct, because A contains also -1.
Answer:
B
Step-by-step explanation:
it cat be a whole number because whole number are set of positive number from 0 and above excluding fraction , negative integer or decimal.
integers include both positive and negative numbers excluding fraction and decimal

Oy=8
O x = 8
O x = 4
O y = 4
Answer:
y = 8
Step-by-step explanation:
A horizontal line will have the form y = k where k is a constant and determines the distance from the x axis. All points on this line will have a constant y value for all x values
Since the line passes through (4,8) we have y = 8 as the equation for the line

What is the difference between the value of the 4 in 25.48 and 12.64
The difference between the values of 4 is 0.36.
We need to understand the place value and face value of a digit in a number.
Place value of digit is decided by putting the number of zeroes equal to the number of digits after that digit.
And the face value of a number is the number itself.
Here the two numbers given is 25.48 and 12.64. And we have to find the difference in place value of 4 in the given number.
The value of 4 in 25.48 is 0.40.
The value of 4 in 12.64 is 0.04.
Required difference = 0.40-0.04
= 0.36

By analyzing and understanding the graph of the absolute value function, we find that the function evaluated at the x-value equal to 1 is equal to the y-value equal to 3.
What is the y-value associated to a given x-value of an absolute value function?
In this problem we find the representation of an absolute value function, where the horizontal axis corresponds to the values of the domain, whereas the vertical axis is for the values of the range. In that picture we must look up for the y-value associated with a given x-value.
Then, we proceed to evaluate the absolute value function at x = 1. In accordance with the graph, the y-value , that is, from the vertical axis, associated with the x-value, that is, from the horizontal axis, equal to 1 is equal to a value of 3.

Meena and some friends are going to the movies. at the theater, they sell a bag of popcorn for $5.50 and a drink for $3.50. how much would it cost if they bought 5 bags of popcorn and 7 drinks? how much would it cost if they bought p bags of popcorn and d drinks?
It would cost-
$27.50 for the 5 bags of popcorn.$24.50 for the 7 drinks.What is cost?In common parlance, cost is the monetary value of products and services purchased by producers and consumers.
Cost is the measure of a alternative opportunities foregone when one good or activity is chosen over others in a basic economic sense. This fundamental cost is commonly known as opportunity cost.Total cost refers to all expense incurred in achieving a specific level of output; dividing such total cost by the quantity generated yields average or unit cost.Total cost = (fixed cost) x Number of units produced.
The cost of a bag of popcorn for $5.50.
The number of popcorn bags bought are 5.
Total cost for 5 bags of popcorn are-
$5.50 ×5 = $27.50.
Thus, Total cost for 5 bags of popcorn bags are $27.50.
The cost of 1 drink is $3.50.
The total number of drinks bought is 7.
Total cost = $3.50×7 = $24.50
Thus, the total cost for the drinks is $24.50.

Step-by-step explanation:
There are several ways that dilation is used in real life. Here are several:
In graphic design. I actually do some graphic design, and I use dilation a lot. It is common to dilate photos to fit the space that you want it to fit.
In police work and crime investigation. Detectives and police dilate photos to see smaller details and evidence.
In architecture. It is normal for architects to make a prototype of their design or building. In order to make the building true to the prototype, they must dilate the scale and measurements.
In the doctor's office. Dilation is used in eye exams so that the eye doctor can view the patient's eye better. After a while it will slowly reduce in size and return back to normal.

y varies directly as the square root of x, and y = 12, when x = 49. Find the value of y when x = 225.
Answer:
180/7
Step-by-step explanation:
Direct variation:
y varies directly as k
y = kx
y varies directly as √x
y = k√x
We need to find k. We use the given data to find k.
y = 12 when x = 49
12 = k√49
12 = 7k
k = 12/7
The equation of direct variation is
y = (12/7)√x
x = 225
y = (12/7)√225
y = (12/7)(15)
y = 180/7

-5(7x-9)-6=144 what is the answer.
Answer: x= -3
Step-by-step explanation:
Answer:
x=-3
Step-by-step explanation:
First you must start by multiplying the parentheses by -5. Once you do that, your equation comes out to -35x+45-6=144. Then you must combine like terms which comes out to -35x+39=144. After that you must get x by itself, so to do that subtract 39 from 144 which comes out to 105. Then you must do the opposite of multiplication and divide 105 by -35 which comes out to x=-3.

Flying to Houston with a tailwind a plane averaged 107 mph. On the return trip the plane only averaged 85 mph while flying back into the same wind. Find the speed of the plane in still air and the speed of the wind
The wind speed and plane speed is 11 and 96 mph.
It is required to find the speed of the plane in still air and the speed of the wind.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Given:
Let plane speed be "p".
Let wind speed be "w".
According to given question we have,
p + w = 107 mph
p - w = 85 mph
By the method of elimination we get,
2p = 192
p = 96 mph
The plane speed is 96 mph.
Solve for "w":
p + w = 107
96 + w = 107
w = 11 mph
The wind speed is 11 mph.
Therefore, the wind speed and plane speed is 11 and 96 mph.

D)Domain: −4 < x < 4; Range: −∞ < y < 4; x-intercept (−1, 0)
The domain of the function is -∝ < x < ∝, the range of the function is -∝ < y < ∝, and the x-intercept of the function is (-1, 0)
How to identify the domain, range, and x-intercept of the function?The equation of the function is given as
g(x) = 4x + 4
The function g(x) is a linear function.
There is no restriction on the input values and output values of a linear function
This means that the domain and the range of a linear function are the set of all real numbers
Set g(x) to 0, to determine the x-intercept
So, we have
4x + 4 = 0
Divide through by 1
So, we have
x + 1 = 0
Evaluate the like terms
x = -1
Hence, the domain of the function is -∝ < x < ∝, the range of the function is -∝ < y < ∝, and the x-intercept of the function is (-1, 0)
