What is absolute value function ?An absolute value function is always positive irrespective of what sign is inside the modulus function as we know if |x| = a then x = a OR - x = -a if we cancel both the negative signs it also becomes |x| = a.
According to the given question we have been given a number line and asked to find the correct statement from the options.
Given two absolute value points |-8| and |6|.
We know |-8| is 8 and |6| is 6.
∴ The correct relation is |-8| > |6|.

Write an equation in slope-intercept form for the line described. x-intercept (-8,0), y-intercept (0,5) The equation of the line is y nothing.
Answer:
y= 5/8 x +5

Step-by-step explanation:
x-intercept is (-8,0)
y-intercept is (0,5)
the slop of line: m= Δy/Δx = (0-5) / (-8-0) = 5/8
y=mx+b
y= 5/8 x +5

The perimeter of the triangle shown to the right is 143 meters. Find the length of each side.
Previa
Hello!
First:
write an equation.
5x + (7x+8) + (7x+2) = 143
now combine like terms
19x + 10 =143
now subtract 10 from both sides
19x = 133
divide 19 on both sides.
x = 7.
Are you done here? Nope, we need to find out what each side is, so lets plug in the number 7 for x.
-----------------------------
For the side 5(x)
5(7) = 35
This side is 35m
-----------------------
For the side 7x + 2
7(7) + 2
49 + 2
51
This side is 51m
------------------------
For the side 7x + 8
7(7) + 8
49 + 8
57
This side is 57m.

Step-by-step explanation:
[tex]8x - 3 = 5 + 4y[/tex]
Isolate y first subtract 5 from both sides
[tex]8x - 8 = 4y[/tex]
Divide both sides by 4.
[tex] \frac{8x - 8}{4} = y[/tex]
[tex]2x - 2 = y[/tex]
y= 1
Step-by-step explanation:
Solve for y:
8x - 3 = 5 + 4y
8x = 4y + 5+3
Divide both sides by 8
x = 1÷2y + 1
plug into equation
8 (1÷2y +1) - 3 = 5 + 4y
Distribute
8÷2+ 8 - 3 = 5 + 4y
4 + 5 -5 = 4y
Combine like item
4 = 4y
divide both sides by 4
y= 1
mark is going to work for his father’s pool cleaning business during the summer. mark’s father will pay him $5 each pool he helps clean. write an algebraic expression to determine how much mark will earn if he cleans n pools. then evaluate the expression for 15, 25, 35, or 45 pools
Answer:
Algebraic Expression: 5n
a. 5(15) = 75$
b. 5(25) = 125$
c. 5(35) = 175$
d. 5(45) = 225$
Step-by-step explanation:
If n represents the amount of pools Mark has cleaned, and he earns $5 for each pool, then 5n will be the algebraic expression. As n represents the number of pools he has cleaned, we need to plug in the given numbers to get the answer, hence [5(15), 5(25), 5(35), 5(45)]. Multiply $5 by the given numbers to get the amount of money Mark would earn if he cleaned the amount of pools.

The diagram represents the fencing around a backyard. The fence is formed with parallel lines and a half circle. Write and solve an equation to determine how many feet of fencing are needed. Round the answer to the nearest tenth.
The amount of fence needed is the perimeter of the fence. The amount of fence needed is 127.1ft
From the diagram of the fence, we have:
[tex]r = 15[/tex] ---- the radius
[tex]l = 40ft[/tex] -- the length of the parallel lines
First, we calculate the length of the arc surrounding the half circle
This is calculated using:
[tex]L = \frac{\theta}{360} \times 2\pi r[/tex]
Because it is a half circle
[tex]\theta = 180[/tex]
So, we have:
[tex]L = \frac{\180}{360} \times 2 \times 3.142 \times 15[/tex]
[tex]L =0.5 \times 2 \times 3.142 \times 15[/tex]
[tex]L =47.13[/tex]
The amount of fence needed is the sum of the length of parallel lines and the semicircle.
So, we have:
[tex]Amount = L + l + l[/tex]
[tex]Amount =47.13 + 40 + 40[/tex]
[tex]Amount =127.13[/tex]
Approximate
[tex]Amount =127.1[/tex]
Hence, the amount of fence needed is 127.1ft

Select three involuntary muscles:
stomach
intestinal
heart
biceps
brain
I'll give Brainliest! :D
Answers:
A) stomachB) intestinalC) heart=============================================
Explanation:
The stomach muscle helps digest food. The muscle isn't something a person can control at will. Instead, the body handles it automatically. This is why choice A is one of the answers.
The intestinal muscles work in a similar fashion to help pass nutrients into the blood stream and also pass waste out of the body. All of these processes are done automatically and you don't have to think about them. They just happen. Therefore, choice B is another answer.
Another example of an automatic or involuntary muscle doing its own thing is the heart muscle. It continuously pumps blood to help distribute nutrients and oxygen, and also dump waste byproducts (eg: carbon dioxide) out of the body. So choice C is the third and final answer.
An example of a muscle that's voluntary are the biceps. You can flex these muscles, and move them around at will. For example, when you pick up an item. So this allows us to rule out choice D.
I'm not sure why your teacher listed "brain". It has properties related to muscles such as the idea of practicing a topic to help retain it (similar to exercising to stay in shape); however, the brain itself isn't a muscle on a technical biological level.
--------------------
Extra info:
Some more involuntary muscles are:
The diaphragm muscle to help the lungs expand and contract (to breathe in oxygen or exhale carbon dioxide).The muscles that allow your eyes to blink. The technical name for them isn't coming to mind at the moment. These muscles blink at some fairly random yet consistent rate, and also blink whenever something like dust particles enter the eye (or threaten to).At some level, you could argue that the biceps are involuntary in some way. What I mean by this is that there's a reflex action to them that is automatically controlled. However, for the most part, the biceps are voluntary muscles.What is the point on the graph of f(x+5)

You have a box of tiles, each of which measures 6 by 10 inches. What is the least number of tiles you could use to form a square region? (Use this square to show how they would be arranged.) The prime factorizations of five numbers are given. Use them to find each of A and В
The least common multiple can be used to find the smallest square formed by equal sized shapes
The least number of tiles to be used is 15 tiles
The arrangement of the tiles, with the 6 inch side as base is 3 rows by 6 columns of tiles
The reason the above responses are correct is as follows:
The unit area of each square tile = 6 inches by 10 inches
Therefore, the area of the square obtained is a factor of 6 × 10 = 60 in.²
The side of the square have 6 and 10 as factors
The lowest common multiple of 6 and 10 is 30
Therefore, the smallest square has a side length of 30 inches and an area of 30 in. × 30 in. = 900 in.²
The least number of tiles = Area/(The area of each tile)
Therefore, the least number of tiles = 900 in.²/(60 in.²/tile) = 15 tiles
The least number of tiles = 15 tiles
The arrangement of the 15 tiles are as follows;
With the 6 inch width side as the base, five tiles are arranged along the base, three more rows are constructed using the same process to form the 30 inch by 30 inch square to give 3 rows by 6 columns of tiles

402 + 39 = 441
Step-by-step explanation:
Counting on means that you start with the biggest number and then count up from there. -hopefully this helped.
The solution is 441
The value of the equation A = 402 + 39 is A = 441
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first number be x = 402

Answer:
tan(205°) = asin(25°) = (a√(a²+1))/(a²+1)cos(65°) = (a√(a²+1))/(a²+1)cos(245°) = -(a√(a²+1))/(a²+1)Step-by-step explanation:
The tangent function is periodic with a period of 180°. So ...
tan(205°) = tan(25°) = a
__
The identity relating sine and tangent is ...
sin(x) = tan(x)/√(tan²(x)+1)
Rationalizing the denominator gives ...
sin(x) = tan(x)√(tan²(x)+1)/(tan²(x)+1)
sin(25°) = a√(a²+1)/(a²+1)
