Answer:
Domain is the set of all x values, the independent quantity, for which the function f(x) exists or is defined.
Step-by-step explanation:
i just graphed it
Answer:
Domain:
[tex]x\in\mathbb{R}[/tex]
Range:
[tex]y\geq -5[/tex]
Step-by-step explanation:
The domain is the span of x-values covered by the graph, and the range is the span of y-values covered by the graph.
From the graph, we can see that the x-values covered by the graph will extend infinitely in both directions. Therefore, the domain of the graph is all real numbers.
We can't write this as an inequality, but we can write:
[tex]x\in\mathbb{R}[/tex]
For the range, we can see from the graph that the lowest y-value is y=-5. The graph doesn't go any lower than that. However, the graph will also cover all values greater than -5. Therefore, the range of the graph is all values greater than or equal to -5. In an inequality, this is:
[tex]y\geq -5[/tex]

let the number be x
so by the question , 2x+5=13
solving this we get ,
2x=13-5
2x=8
so x=4
Answer:
the number is 4
Step-by-step explanation:
let the number be ''x''
than twice the number will be 2x
now,
2x + 5 = 13
2x = 13 - 5
2x = 8
x = 8/2
x= 4

14. The range of the data 6, 8, 16, 22, 8, 20, 7, 25 is __________.
Answers
Answer:
The range of the data is 19.
Step-by-step explanation:
To solve this problem, we must remember that to calculate the range, we subtract the smallest data point in the set from the largest data point. In this case, the largest number is 25 and the smallest number is 6.
Therefore the range is:
25 - 6
= 19
Hope this helps!
Answer:
The range is 19
Step-by-step explanation:
6, 8, 16, 22, 8, 20, 7, 25 is
List the numbers from smallest to largest
6, 7,8, 8 ,16,20, 22,25
The range is the largest number minus the smallest number

Mr. Drew wants to build a square sandbox with an area of 361 square feet. What is the total length of the wood Mr. Drew needs make the sides of the sandbox
Answers
Answer:
The Sandbox must be 19x19 for the area to be 361.
Step-by-step explanation:
(19x19=361)
The length of the sandbox will be 19 feet.
What is the area of the square?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the square in a two-dimensional plane is called the area of the square.
Given that Mr. Drew wants to build a square sandbox with an area of 361 square feet.
The length will be calculated by using the area formula for square;
Area of square = Length x width
Then the area of the square can be written as;
Area of square = ( Length )²
361= ( Length )²
( Length ) = √361
( Length ) = 19feet
Therefore, the length of the sandbox will be 19feet.

Mandy's science class counted the bones in an owl pellet.
How many more rib bones were there than skull and jaw bones combined?
Answers
You take the number of skull bones, which is 1(2), and add that to the number of jaw bones, which is 0. Giving you a total of 2 bones.
Then you are taking the rib bones 3(2) and finding out that you have 6.
So with that information, you can find out that there are 4 more rib more than skull and jaw bones combines (6-2=4)

A 3% salt solution weighing 100g represents 100g of water in which 3g of salt is dissolved (=3/10). What amount of salt would be combined in 100g of a 14% salt solution? And how many grams of water are in the same solution?
Answers
Answer:
There would be 12 g of salt (12.3 g actually but rounded) and 88g of water (88.7 g actually but rounded)
Step-by-step explanation:
From the question, a 14% salt solution means 14g of salt in 100g of water.
What this means is that, the fraction of salt to water in the solution would be 14/100 which is same as 7/50
Now, we want to know the amount of salt and the amount of water in a 100g of 14% salt solution.
Looking at the ratio salt to water, we have 7 to 50
For every 50 parts of water, there are 7 parts of salt.
So the ratio of both is 7:50
For salt, the amount in grammes present will be ;
7/(50 + 7) * 100g = 7/57 * 100 = 12.3 g or 12g to the nearest whole number
The amount in grammes of water present will be ;
50/(50 + 7) * 100g = 50/57 * 100 = 87.7g or 88g to the nearest whole number

Mario and Luigi want to purchase some extra controllers for their friends. Each controller costs $29.99. Use an algebraic expression to describe how much they will spend in total, before sales tax, based on purchasing the console, the number of games, and the number of extra controllers
Answers
Answer:
C = 299x + 59.99y + 29.99z
Step-by-step explanation:
An algebraic expression is an expression in which it involves the numbers like 1,2,3 also it includes the operations such as additions, subtraction, multiplication, etc
Fo mentioning an algebraic expression, we do have following components
x = number of consoles purchased
y = number of games purchased
z = number of controllers purchased
C = total cost
Also, the total cost would be equivalent to the sum of the price and then it multiplied with the numbers as stated above
So, the algebraic expression is
C = 299x + 59.99y + 29.99z

Lydia guessed there were 180 jelly beans in a container.
There were actually 220 jelly beans in the container.
What was Lydia's percent error?
Answers
Answer:
18.18% error
Step-by-step explanation:
Use the percent error formula,
% error = | (measured - accepted) / accepted | x 100
Plug in the values we know:
% error = | (180 - 220) / 220 | x 100
% error = | - 0.18 | x 100
% error = 18.18% error

3. The sides of a triangular birdcage are consecutive integers. If the perimeter is 114 centimeters, what is the length of each side? Label each side with an expression that represents its length.
Answers
Answer:
Sides of the triangular birdcage are 37 cm, 38 cm, 39 cm.
Step-by-step explanation:
In the given triangular birdcage, sides of the triangle are consecutive integers.
Let sides of the triangle are x, (x + 1), (x + 2) cm.
Perimeter of a triangle = Sum of all sides of the given triangle
114 = x + (x + 1) + (x + 2)
114 = 3x + 3
3x = 111
x = [tex]\frac{111}{3}[/tex]
x = 37
Therefore, sides of the triangular birdcage are 37 cm, 38 cm, 39 cm.
A canoe traveled Downstream with the current and went a distance of 15 miles in three hours. On the return trip, the canoe traveled Upstream against the current. It took 5 hours to make the return trip. Find the rate of the current
Answers
Answer:
1 mile/hr
Step-by-step explanation:
Let the Speed of the boat still in water = a
Speed of the current = b
We know from this formula that speed = distance/time
Hence,
A canoe traveled Downstream with the current and went a distance of 15 miles in three hours.
Downstream = a + b = 15/3
a + b = 5 .........Equation 1
On the return trip, the canoe traveled Upstream against the current. It took 5 hours to make the return trip.
Upstream = a - b = 15/5
a - b = 3 ..............Equation 2
Combining both Equation together
a + b = 5 .........Equation 1
a - b = 3 ..............Equation 2
Subtracting Equation 2 from Equation 1
2b = 2
b = 2/2
b = 1miles/hr
Since b = speed of the current which can also be called rate of the current, the rate of the current = 1 miles/hr
