2 is the input value, while 6 is the result.
We know the rule is Multiply the input by 6 to get the output.
= (2*5)-4
=10-4
=6.
A function rule is the equation-based relationship between dependent and independent variables. How to calculate the value of the dependent variable, say y, in terms of the independent variable, say x, is explained by the function rule of a particular function. A function table includes a function rule as well as input and output values. If we plug in various values for the input, we obtain corresponding values of output according to the function rule. The relationship between the input values x and the output values y always follows a pattern that is specified by the function rule.
Hence, the input and output value of a table is 2 and 6.

f (x) = x^2 + 1 g (x) = 5 - x ( f + g)(x) =
The value of (f + g)(x) can be find out by adding both given functions f(x) and g(x) and its value will be x² - x + 6.
What is function ?
A function is a relationship between inputs and outputs where each input has precisely one output and the output can be linked to its input.
The given functions are :
f(x) = x² + 1
g(x) = 5 - x
We now have to find the value of (f + g)(x).
We know that the value of (f + g)(x) can be calculated by simply adding the values of both given functions which are f(x) and g(x).
So ,
(f + g)(x) = f(x) + g(x)
Now , let's substitute the values of both functions f(x) and g(x) into the above equation , so we will get :
(f + g)(x) = (x² + 1 ) + (5 - x)
Rearranging and solving the terms we get the value of (f + g)(x) as :
(f + g)(x) = x² - x + 6
Therefore , the value of (f + g)(x) can be find out by adding both given functions f(x) and g(x) and its value will be x² - x + 6.

In your job as a metalworker you need to cut 2 peices from a sheet of steel that is 13 1/4 in long after u cut one peice measuring 2 3/4 in and another measuring 31/4 in. How many in of steel you got left
11/4 or 2.75 part is remaining out of 13 ¼
Total sheet of steel will be 13 ¼
So dividing the whole sheet into 3 parts : let one piece be x and other be y and the remaining be z
as per the question x=2 3/4 and y amounts to = 31/4
so we need to find z
x + y + z= 13 1/4 (equation 1)
substituting the value of x= 2 3/4 and y = 31/4 in equation 1
2 3/4 + 31/4 + z= 13 1/4
converting mixed fraction into improper fraction
11/4 + 31/4 + z =53/4
z =53/4 -(11/4 + 31/4)
z = 11/4
hence z= 11/4
Therefore, out of 13 ¼, 11/4 or 2.75 part remains

Given the system of constraints, name all vertices. Then find the maximum value of the given objective.
The maximum value of the objective C = 5x -4y over given constraints is
What is system of constraints?In any optimization problem, when we need to either maximize or minimize some objective function for that we are given some limitations or logical conditions which the objective function needs to satisfy in order to maximize or minimize.
These constraints are in the form of equalities or inequalities, where a feasible region satisfying all these equalities or inequalities is first found and then we maximize/minimize our objective on the boundary points of this feasible region.
Given problem is:
Maximize Objective function C = 5x-4y
When system of constraints are (i) x≥0 , (ii) y≥0 , (iii) 4 ≤y+ x
(iv) y ≤ (1/5)x +1
We will graph this system of constraints to find the feasible area.
x≥0,y≥0 represents that feasible area is in the 1st quadrant
For 4 ≤ x + y, we will use corresponding x+ y = 4 equality
When x= 0 then y=4 and when y=0 then x=4 , then y+ x = 4 is a line passing through (0,4) and (4,0)
When be substitute (0,0) in 4 ≤ x + y we get 4 ≤0 which is a false statement .
Therefore,4 ≤y + x is the region starting with line x+ y = 4 and area above this line in opposite direction of origin.
For y ≤ (1/5)x +1, we will use y = (1/5)x +1, put x= 0 we get y=1 and put y=0 then x= -5 , then y= (1/5)x +1 is a line passing through (0,1) and (-5,0)
And on substituting (0,0) in y ≤ (1/3)x +1 we get 0 ≤ 1 which is a true statement .
Therefore, y ≤ (1/5)x +1 is region including the line y = (1/5)x +1 and area on the side of this line that is towards origin
The feasible region is shown in the attached picture with the boundary points of the shaded area.
ABC is the shaded area is feasible area, where A= (0,4) ,B= (2.5, 1.5 ), C= (0,1)
Z at A : 5(0) -4 (4) =-16
Z at B : 5(2.5) -4(1.5) =6.5
Z at C : 5(0) -4(1) = -4
Clearly, maximum value of z in feasible area is Z= 6.5 at point (2.5, 1.5)

Each day Donna and Mary toss a coin to see who buys the other person coffee ($1.73 a cup). One tosses and the other calls the outcome. If the person who calls the outcome is correct, the other buys the coffee; otherwise the caller pays. Assume that an honest coin is used, that Mary tosses the coin, and that Donna calls the outcome. Find Mary's expected payback. Is this a fair game?
Mary's expected payback based on the information illustrated is 0.865. This isn't a fair game.
How to calculate the probability?Based on the information, the chances of Donna winning will be 1/2.
It was also stated that each day Donna and Mary toss a coin to see who buys the other person coffee ($1.73 a cup).
Therefore, Mary's expected payback will be:
= (0 × 1/2) + (1.73 × 1/2)
= 0 + 0.865
= 0.865.
Therefore, Mary's expected payback based on the information illustrated is 0.865. This isn't a fair game.

What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The magnitude of an earthquake is related to the relative intensity by which of the following formulas?
magnitude = log(relative intensity)
magnitude = relative intensity
magnitude = 10relative intensity
magnitude = 10 log(relative intensity)
The magnitude of an earthquake is related to the relative intensity by
magnitude = log(relative intensity).
Magnitude is a measure of earthquake size and remains unchanged with distance from the earthquake. Intensity, however, describes the degree of shaking caused by an earthquake at a given place and decreases with distance from the earthquake epicentre.
A better measure of the size of an earthquake is the amount of energy released by the earthquake, which is related to the Richter Scale by the following equation:
Log E = 11.8 + 1.5 M
(where Log refers to the logarithm to the base 10, E is the energy released in ergs and M the Richter magnitude).
Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location. Intensity is determined from effects on people, human structures, and the natural environment.
An earthquake's magnitude is inversely proportional to its relative intensity (magnitude = log) (relative intensity)
