What is the mathematical operation?An operation, often known as "operand" or "argument," is a function in mathematics that converts zero or more input values into a clearly defined output value. The operation's arity is determined by number of operands.
Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are operations that are most frequently studied. A constant is operation with arity zero, often known as a nullary operation. An example of an operation of arity 3, sometimes known as ternary operation, is the mixed product.
The arity typically assumed to be limited. The "typical" operations of finite dimensionality are referred to finiteary operations when infinitary operations are taken into consideration.
Similar to an operation, but with partial function in place of a function, is the definition of a partial operation.
A closed or filled-in circle represents greater/lesser or equal to symbol (> or with the line at the bottom).
You must flip the inequality sign when multiplying or dividing when one of terms is negative on both sides. In inequality equations, this rule only holds when multiplying or dividing by negative value. This rule is very crucial.
-5c + 2 _< _27
subtract from both sides by 2
-5c _< _ 27
divide both sides by -5
c _< _ 5.4
flip the inequality sign
c _> _5.4

help with this math problem am stuck on please.
Identify the equation of the line that is perpendicular to y = −12x +7 and passes
through the point (8, 5).
The equation of the line that passes through the point (8, 5) and perpendicular to y = −12x +7 is y = (1/12)x + 13/3.
We know that,
The product of the slopes of two perpendicular lines is -1.
The slope intercept form of a line is given by :-
y = mx + c
Comparing it with y = -12x + 7
We get,
m = -12 (slope of the line)
c = 7 (y-intercept of the line)
Let the slope of the line perpendicular to the given line be n.
Hence, we can write,
(-12)*n = -1
n = 1/12
Also, the line passes through (8,5).
Hence, we can write,
5 = (1/12)(8) + c
5 = 2/3 + c
c = 5 - 2/3 = 13/3
Hence, the equation of the line is given by :-
y = (1/12)x + 13/3

Answer:
Part A: no. The bikes/skateboards labels are reversed
Part B: 8/25 = 0.32; Fraction of students with both bikes, skateboards
Step-by-step explanation:
Given a segmented bar chart, you want to know if it was drawn correctly, and you want to know the value and meaning of the greatest joint relative frequency.
Part AYou want to know if the given segmented bar chart is an appropriate representation of the data in the 2-way table.
The bar chart is created incorrectly.
There are at least a couple of problems with the chart.
The title suggests it will show numbers of students. Instead it shows the fraction (%) of students in each category.The column labels suggest the first column represents the distribution of skateboarders among students who have bikes. Instead, the column actually shows the distribution of bikers among students who have skateboards. (The labels are reversed.)A correctly drawn chart would be incapable of answering the question in Part B. If it is the intention to answer that question using the chart, a different type of chart is needed: a stacked bar chart showing numbers (or relative frequencies) of students in each category.Part BThe largest number in the table is 80. The fraction that is of the whole is ...
80/(70+30+80+70)
= 80/250 = 8/25 = 0.32
The greatest relative frequency is 0.32. It represents the fraction of students who have both bikes and skateboards.

Answer:
[tex]\frac{9x^{2}}{y^{2}}[/tex]
Step-by-step explanation:
First you need to do what is inside the parenthesis
Dividing by a variable with the same base means the powers subtract so if we do this for x we get.
[tex]\frac{x^{\frac{1}{2}}}{x^{-\frac{1}{2}}}=x^{\frac{1}{2}-(-\frac{1}{2})}=x^{1}=x[/tex]
That brings us to
[tex](\frac{3xy^{-\frac{1}{2}}}{y^{-\frac{1}{2}}})^2[/tex]
Then we need to do a similar process for the y variable.
[tex]\frac{y^{-\frac{1}{2}}}{y^{\frac{1}{2}}}=y^{-\frac{1}{2}-(\frac{1}{2})}=y^{-1}=\frac{1}{y}[/tex]
Which brings us to
[tex](\frac{3x}{y})^2[/tex]
From here we just need to square the top and the bottom of the fraction which brings us back to our final answer with

On subtracting "3a – 7b + 12c" from "-5a – 21b + 3c" we get -
- 8a - 14b - 9c
What is subtraction?
Subtraction is an arithmetic operation that represents the operation of removing objects from a collection. Subtraction is signified by the minus sign −.
Given is to subtract "3a – 7b + 12c" from "-5a – 21b + 3c".
Assume that -
A = 3a – 7b + 12c
B = -5a – 21b + 3c
B - A = (-5a – 21b + 3c) - (3a – 7b + 12c)
B - A = -5a - 21b + 3c - 3a + 7b - 12c
B - A = -5a - 3a - 21b + 7b + 3c - 12c
B - A = - 8a - 14b - 9c

Exit. how do I solve this ???
Tate and Nathan will leave $ 19.48 to the server to cover up the bill and the tip when they go out to dinner at Red Robin.
As given in the question,
Since Tate and Nathan both order burgers for $12.49 each,
Total amount payable is
$12.49 + $12.49= $24.98.
Now 18% tip is equal to
18% of $24.98
(18/100) × 24.98
= $4.4964
= $4.50 (rounded to nearest cent).
Total gross amount payable (including 18% tip) is
24.98 + 4.50 = $29.48.
Now subtracting the birthday coupon for $10.00 off,
the net amount payable in the bill is
29.48 - 10.00
= $ 19.48
= 19.48 cents
Therefore, after using the coupon, they will leave the server $19.48 to cover the bill and the tip.

MK= 12.5
AngleJNK=117°
AngleJNM=63°
Step-by-step explanation:
Part A:
MN = 3x + 1
JL = 2x + 9
JL and MK are the diagonals
MN = 1/2 of MK
MK =2(3x +1)
MK = 6x + 2
Therefore, JL = MK
2x + 9 = 6x +2
Collect like terms
2x-6x = 2 - 9
-4x = - 7
x = 1.75
Substituting the value of x,
MK = 6(1.75) + 2
MK = 10.5 + 2
MK = 12.5
Part B
AngleJNK = (5x +2)°
AngleJNM = (3x-6)°
Sum of interior angles of a quadrilateral = 360
Therefore, 2(5x +2)° + 2(3x-6)° = 360
(10x + 4) + (6x - 12) = 360
Collect like terms
10x + 6x - 12 + 4=360
16x = 360 + 8
16x = 368
x = 368/16
x = 23
