The inverse of 1 is 1. If we convert 1 into a fraction number we will get 1/1 then the reciprocal of 1/1 is again 1/1 which is equal to 1.
The inverse of a number is it's reciprocal. Consider a number y where y is not equal to zero. Then the inverse of y is the reciprocal of the y that is 1/y.
The inverse is a function or an operation which reverses the order of operation of another function or an operation”.
For example, Calculate the inverse of a number 7, 17, 37 and 47.
To find out the inverse of a number, we have to take the reciprocal of the given numbers.
So, the inverse of the number 7 will be 1/7.
The inverse of the number 17 will be 1/17.
The inverse of the number 37 will be 1/37.
The inverse of the number 47 will be 1/47.

The minimum number of $5-notes she has 32/3
Now, According to the question:
Siti opened her money box to find 50 pieces of $5-notes and $2-notes.
If the total value of all the notes is more than $132.
To find the minimum number of $5-notes she has
Based on the given condition:
= 2 × (50 - x) + 5x = 132
Apply Multiplicative Distributive law:
100 - 2x + 5x = 132
Rearrange the unknown terms on left sides of the equation:
-2x + 5x = 132 - 100
Combine like terms:
3x = 132 - 100
Calculate the sum or difference:
3x = 32
Divide the both sides of the equation by the coefficient of the variable:
x = 32 ÷ 3
Rewrite as fraction :
x = 32/3
Hence, the minimum number of $5-notes she has 32/3

m∠ABC=(8x−48)°, m∠ABD=44°
Answer: m∠ABC and m∠ABD are the measures of angles in a triangle. The sum of the measures of the angles in a triangle is always 180°.
So if we know two of the angles, we can use this information to find the measure of the third angle.
Given that m∠ABC= (8x-48)°, m∠ABD=44°
we can find the measure of the third angle, m∠BCD by:
m∠ABC + m∠ABD + m∠BCD = 180
(8x-48) + 44 + m∠BCD = 180
m∠BCD = 180 - (8x-48) - 44
m∠BCD = 180 - 8x + 4
m∠BCD = (180 - 8x + 4)°
However, Since we don't know the value of x, the measure of angle BCD is not determined.
Step-by-step explanation:
△DSJ≅△RCW. If m∠D=114 m∠J=42 ∘ , find m∠C.
The measure of angle m ∠C is 24°.
What are congruent triangles?Congruent triangles have both the same shape and the same size.
Given is that △DSJ ≅ △RCW and m ∠D = 114 and m ∠J = 42.
Since △DSJ ≅ △RCW, we can write -
m ∠S = m ∠C
Now, in △DSJ, we can write -
m ∠D + m ∠S + m ∠J = 180
m ∠S = 180 - 156
m ∠S = 24 = m ∠C
Therefore, the measure of angle m ∠C is 24°.

What mistake did the student make in the picture provided? How would you correct the error?
The mistake made is the error in finding the value of the slope, m, of the line.
The error can be corrected by plugging in m = 6/3 = 2 in the equation; y = m·x + b
What is the slope of a line?The slope of a line is the ratio of the rise to run of the points on the graph of the line.
The points on the graph of the line are; (0, -2), and (3, 4)
The slope of the line, m, can be found using the formula;
m = (y₂ - y₁)/(x₂ - x₁)
Where for the line in the question, we get;
(x₁, y₁) = (0, -2)(x₂, y₂) = (3, 4)Therefore;
Slope, m = (4 - (-2))/(3 - 0) = 6/3 = 2
The slope of the line = 2
The equation of the line in point-slope form is therefore;
(y - 4) = 2·(x - 3)
y = 2·x - 6 + 4 = 2·x - 2
y = 2·x - 2
The equation can also be found using the x-intercept as follows;
At the x-intercept, x = 0. The x-intercept is therefore, the point (0, -2)
The equation of the line in the slope-intercept form is, y = m·x + b, where b is the y-value at the x-intercept is therefore;
y = -2, when x = 0
-2 = 2×0 + b
b = -2
y = m·x + b, therefore; y = 2·x - 2
The mistake of the student is therefore;
The value of the slope of the graph of the line is 6/3 = 2The error can be corrected by plugging in m = 2 in the equation, y = m·x + b as follows;y = m·x + b
4 = 2·(3) + b

Zendaya invests money in an account paying a simple interest of 7.3% per year. If she invests $70 and no money will be added or removed from the investment, how much will she have in one year, in dollars and cents?
Answer: If Zendaya invests $70 in an account paying a simple interest of 7.3% per year, and no money will be added or removed from the investment, she will have $75.11 in one year.
To calculate the amount of interest earned, you can use the formula:
Interest = Principal x Rate x Time
where
Principal = $70
Rate = 7.3/100 (expressed as a decimal)
Time = 1 year
So the interest earned is:
$70 x 0.073 x 1 = $5.11
To find the total amount at the end of the year, you add the interest to the original principal:
$70 + $5.11 = $75.11

What are rational expressions ?
Rational expressions represent the relationship between two polynomials. It signifies that the numerator and denominator are both polynomials in it. It is an algebraic expression ratio with an unknown variable, similar to a fraction. We may, however, simplify this type of equation with the aid of a calculator.
Addition and subtraction: When adding or subtracting rational expressions with the same (or similar/common) denominator, keep the denominator alone. If possible, reduce the remaining expression.
If the rational expressions have different denominators, then LCM is applied first. Change each rational expression to its equivalent by changing the denominator exactly. Finally, combine or delete similar phrases. If feasible, reduce the remaining expression.
Multiplication: Factor the polynomial numerators and denominators (if any exist); then reduce wherever possible. Reduced form is obtained by multiplying the remaining numerators and denominators independently.
Division: Invert the denominator (or divisor) and multiply it with the first rational expression (i.e. dividend or numerator) since reduction can only be done simply after changing the division into multiplication, as with fractions. As previously demonstrated, further simplification is equivalent to multiplication.
Now ,
Given rational expression is =4(x-1)/(x-1)(x+5)
=4/(x+5) ( x-1 is same in numerator and denominator so cut it)

The pair of linear equations 3x + 4y + 5 = 0 and 12x + 16y + 15 = 0 has no solution.
To find the number of solutions that a pair of linear equations will have, we can use the concept of the ratio of coefficients.
For the pair of linear equations:
3x + 4y + 5 = 0
12x + 16y + 15 = 0
We can find the ratio of the coefficients of x in both equations.
In the first equation, the coefficient of x is 3 and in the second equation, the coefficient of x is 12. The ratio of these coefficients is
3/12 = 1/4
We can also find the ratio of the coefficients of y in both equations.
In the first equation, the coefficient of y is 4 and in the second equation, the coefficient of y is 16. The ratio of these coefficients is
4/16 = 1/4
As both ratio are equal, let us check ratio of constants.
