Answer:
A, B
Step-by-step explanation:
An irrational number is a number that cannot be expressed as a fraction for any integers and. Irrational numbers have decimal expansions that neither terminate nor become periodic.
A (bc sqrt7 doesn't terminate)
B (bc pi doesn't terminate)
the others are rational

Answer:
a.) 0.671
b.) 0.985
c.) 0.137
Step-by-step explanation:
Ok..this is easy when you do it a specific way....
a.)
You can easily do 5 - 4.329 and it will give you 0.671.
Now you can do 5 - 0.671 and it will give you the answer as 4.329.
And you got your answer.
The missing value for equation a = 0.671.
b.)
You can easily do 1 - 0.015 and it will give you 0.985.
Now you can do 1 - 0.985 and it will give you the answer as 0.015.
And you got your answer.
The missing vaule for equation b = 0.985.
c.)
You can easily do 1 - 0.863 and it will give you 0.137.
Now you can do 1 - 0.137 and it will give you the answer as 0.863.
And you got your answer.
The missing value for equation c = 0.137
All you have to do is subtract the first number they gave you (the top one), with the actual answer the give you (at the bottom)

x + 2x + 3 + 3 = 3(x + 2)
Answer:
x = 3
Step-by-step explanation:
cuz x + 2x + 3 + 3 = 3(x+2)
replace x with 3
3 + 2(3) + 3 + 3 = 3(3+2)
3 + 2(3) = 9 + 3 = 12 + 3 = 15
3(3+2) = 15
Pls can i be brainliest...
Answer:
Step-by-step explanation:
x + 2x + 3 + 3 = 3(x + 2)
Do the distributive property
x + 2x + 3 + 3 = 3 * x + 3 * 2
x + 2x + 3 + 3 = 3x + 6
Combine like terms
3x + 6 = 3x + 6
Subtract 6 on both sides
3x + 6 - 6 = 3x + 6 - 6
3x = 3x
As you can see, they are the same...which means
Any value of x makes the equation true. All real numbers
1, 2, 3 , 4 etc
Any value u put into the equation to represent "x" will be true...
EX:
3x = 3x
( if x were 7 we substitute that)
3(7) = 3 (7)
21 = 21 CORRECT
They will be the same answer/ have the same value.
Hope this helped!

Answer:
Elizabeth had 30 stamps originally.
Step-by-step explanation:
Let,
x be the number of stamps Elizabeth have.
Number of stamps given to John = 1/6 of x = [tex]\frac{1}{6}x[/tex]
Remaining stamps = [tex]x-\frac{1}{6}x = \frac{6x-1x}{6} = \frac{5}{6}x[/tex]
Stamps given to Peter = 1/5 of remainder = [tex]\frac{1}{5}*\frac{5}{6}x = \frac{1}{6}x[/tex]
Number of stamps left = 20
Now,
[tex]\frac{1}{6}x + \frac{1}{6}x + 20 = x\\\\\frac{1x+1x+120}{6} = x\\\\\frac{2x+120}{6} = x\\\\2x + 120 = 6x \\\\120 = 6x - 2x \\\\120 = 4x \\4x = 120[/tex]
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{120}{4}\\x=30[/tex]
Hence,
Elizabeth had 30 stamps originally.

What does 2 to the power of 8 equal?
Answer:
2^8 is equal to 256
Step-by-step explanation:
Which of the following are characteristics of the graph of the absolute value
parent function?
Check all that apply.
O A. It goes through the origin.
O B. The right half has a slope of -1.
O C. It is in quadrants I and II.
D. It is V-shaped.
Answer: C) It is in quadrants I and II
A) It goes through the origin
D) It is V-shaped
explanation: The graph of the absolute value parent function will be V-shaped. The absolute function is also known as the mode function. The value of the absolute function is always positive. The absolute function is given as f(x) = | x – h | + k
The graph of the absolute value parent function will be V-shaped.
The characteristics of the graph of the absolute value parent function are; A) It goes through the origin, C) It is in quadrants I and II and D) It is V-shaped
What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|x| = x, x ≥ 0.
|x| = -x, x < 0.
This measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0, and has vertex at (0,0). The range is from the y-coordinate of the vertex to positive infinity.
Vertex (2, 0), Range: {y | 0 ≤ y < ∞}
Since graph of the absolute value parent function will be V-shaped. The absolute function is also known as the mode function.
The value of the absolute function is always positive. therefore the absolute function is given as ;
f(x) = | x – h | + k
The graph of the absolute value parent function will be ;V-shaped.

Jim buys a skateboard for $200. The value of the skateboard depreciates by 15% each year
since buying it. Create a function to represent the value of the skateboard, f(2), in dollars,
after 3 years since buying it.
Answer: f(x)=200•(0.85)^x
Step-by-step explanation:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
Depreciation is often modeled as an exponential decay function. Since Jim bought a skateboard for Co=$200, its value will depreciate by r=15% = 0.15 each year since buying it.

In ΔLMN, n = 92 inches, ∠N=46° and ∠L=11°. Find the length of l, to the nearest inch.
Answer:
24 inches
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. The types of triangles are scalene triangle, equilateral triangle, right angled triangle and obtuse triangle.
Sine rule states that given a triangle with sides a, b, c and their corresponding angles opposite to the sides as A, B, C. Then:
[tex]\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}[/tex]
In triangle LMN:
We can find the length of l using sine rule:
[tex]\frac{l}{sinL}=\frac{n}{sinN} \\\\substituting:\\\\\frac{l}{sin(11)}=\frac{92}{sin(46)} \\\\l=\frac{92}{sin(46)}*sin(11)\\\\k=24\ inches \\[/tex]

The function f(x) is a quadratic function and a limited table of values is provided
below. Write the equation of the quadratic polynomial in standard
form.
Answer:
x^2 - x - 12
Step-by-step explanation:
The quadratic will have the form f(x) = ax^2 + bx + c
Note that when x = 0, y = -12. Thus, we have f(0) = a(0)^2 + b(0) + c = -12, and the function (so far) is f(x) = ax^2 + bx - 12.
Arbitrarily choose two more ordered pairs from the table. I've chosen (-3, 0) and (-4, 8).
For (-3, 0), the quadratic becomes 0 = a(-3)^2 + b(-3) - 12, or:
0 = 9a - 3b, and
For (4, 8), f(4) = 8 = a(4)^2 + b(8), or 8 = 16a + 8b, or 1 = 2a + b, or b = 1 - 2a
Solve 0 = 16a + 4b and b = 1 - 2a for a and b.
Let's use substitution: Substitute b = 1 - 2a into 0 = 9a - 3b or 3a - b = 0:
3a - 1 - 2a = 0, or a = 1.
Since b = 1 - 2a, we get b = 1 - 2(1) = -1
and so a = 1, b = -1 and c = -12
Then the polynomial must be: x^2 - x - 12
Point B (-4,4) and D (10,4) lie on circle G. The line segment connecting the two points
Answer:
BD = 14units
Step-by-step explanation:
To get the distance of the line connecting the two points, we will use the formula for calculating the distance between two points
D = √(x2-x1)²-(y2-y1)²
D = √(10-(-4))²-(4-4)²
D = √(10+4)²
D = √(14)²
D = 14unit
Hence the distance between the two points is 14units
