Most people would notice a major, expensive purchase that they did not make. A smaller, incorrect charge of $6, for example, might go unnoticed unless the entire statement was checked with a calculator. If one million credit card holders were each overcharged $6 each month for five years, what would be the total amount that debtors were overcharged, not including the extra
finance charges? million
The total amount that debtors are overcharged is 360 million dollars.
The unitary method is a technique to find the necessary value by multiplying the single unit value by finding the value of single unit value. We will use the same technique to solve this problem
According to question, $6 is charged per month for 5 years period from 1 million credit card holders
so, the total amount will be

What is limit of a function how can limit be interpreted using graph of that function?
Limit : Limit is the value that a function output approaches as the input approaches to a certain value.
For any function g(x) ,[tex]\lim_{x \to \22} g(x)[/tex] means that the value g(x) approaches as the x approaches to 2 .
From any graph we can easily see that to what value g(x)=y on the curve is approaching when the x is approaching to some value on x axis and if the graph is breaking on the value where x is approaching then the limit does not exist for that value of x.
For given graph
We can see value of value of function g at x=0 is 5 and value of function g at x=1 is 4
As the graph is breaking on x=0 into two functions then [tex]\lim_{x \to \00} g(x)[/tex] or limit of g(x) at x=0 does not exist
As the graph is not breaking at x=1 or we can say that graph of g(x)is approaching to 4 as x approaches to 1 then [tex]\lim_{x \to \11} g(x)[/tex] or limit of g(x) at x=1 is equal to g(1) that is 4

Step-by-step explanation:
Solve:

7x - 28 = 8x - 14
Substrate 8x from both sides.
7x - 28 - 8x = 8x - 14 - 8x
-x - 28 = -14
Add 28 to both sides.
-x - 28 + 28 = -14 + 28
-x = 14
Divide both sides by -1.
-x/-1 = 14/-1
x = -14
Therefore x = -14

What exactly seems to be "triangle congruency?"Two triangles are said to be congruent when their three corresponding sides and angles are the same size.To appear identical, these triangles can be moved, rotated, flipped, and turned.They will align if they are moved.Congruence exists when two triangles meet the five congruence conditions.They are the side-side-side (SSS), the side-angle-side (SAS), the angle-side-angle (ASA), the angle-angle-side (AAS), and the right angle-hypotenuse-side (RHS).So,

The distance of AB is 2√5.
Given that the point A is (2,-1) and point B is (4,3).
The distance formula gives us the shortest distance between the given two points in a plane of two dimensional.
The given points is point A(x₁,y₁)=(2,-1) and point B (x₂,y₂)=(4,3).
Now, we will use the distance formula to calculate the distance that is D=√(x₂-x₁)²+(y₂-y₁)².
Further, we will substitute the given values in the above formula, we get
D=√(4-2)²+(3-(-1))²
D=√2²+(3+1)²
D=√2²+4²
D=√4+16
D=√20

Step: Solve4x+2y=10for x:
4x+2y=10
4x+2y+−2y=10+−2y(Add -2y to both sides)
4x=−2y+10
4x/4 = −2y+10/4

Percentage is the fraction of an amount expressed as an amount out of 100. Percentage is a measure of frequency. The sign used to represent percentage is %.
Price of the skateboard after the first discount = (1 - discount) x initial price
(1 - 0.30) x 119.50
