The parameters are ΔUVW with side UW extended to X then m ∠UVW = (3x + 4)°, m ∠VWX = (8x -12)° and m ∠WUV = (x + 20)° then the value of x = 9°.
How to estimate the value of x?The given parameters exist;
ΔUVW with side UW extended to X
m ∠UVW = (3x + 4)°, m ∠VWX = (8x -12)° and m ∠WUV = (x + 20)°
We have that m ∠UVW + m ∠WUV + m ∠VWU = 180° (Sum of the interior angles of a triangle theorem)
Therefore, m ∠VWU = 180° - (m ∠UVW + m ∠WUV)
Also, we have that m ∠VWX and m ∠VWU exist supplementary angles, (The sum of angles on a straight line)
∴ m ∠VWX + m ∠VWU = 180° (Definition of supplementary angles)
m ∠VWU = 180° - m ∠VWX
∴ m ∠VWX = (m ∠UVW + m ∠WUV)
Substituting the values in the above equation, we get;
(8x -12)° = (3x + 4)° + (x + 20)°
simplifying the above equation, we get
8x - 3x - x = 4 + 20 + 12
4x = 36
x = 36/4 = 9
Therefore, the value of x = 9°.

What is the inverse function of y=2^-x?
Answer:
Step-by-step explanation:
Find the Inverse y=2x. y=2x y = 2 x. Step 1. Interchange the variables. x=2y x = 2 y. Step 2. Solve for y y
Answer: The inverse of the function y = 2x2 + 2 is f-1(x) = √(x - 2) / √2.
If f(x) = 7(2x - 9), find f^-1(x).
The inverse of the given function is f^-1(x)= (x - 63) /14
What is an inverse?A function's reverse function F is a function that reverses the action of f (sometimes known as the inverse of f). If the inverse of f exists, it is designated by f -1 and exists only if f is bijective. The graph of the inverse of a function shows the function and the inverse of the function, which are both plotted over the line y = x. This graph's line traverses the origin and has a slope value of 1.
The first step is to open the brackets
So now we get, f(x)= 14x - 63
Let f(x) be y so this becomes y= 14x+ 63
Now interchange the variables and we will get
x= 14y+ 63
(x- 63)/14= y
Replace y by f^-1(x).

Add parenthesis and grouping symbols to each order of operations problem to make the equation true.
1. 4 ✖️ 3 + 7 - 6 ✖️ 1 + 4 = 20
2. 60 - 18 ➗ 2 + 4 + 10 ➗ 2 = 12
3. 80 - 36 ➗ 2 + 6 - 2 ✖️ 5 + 1 = 44
4. 3 ✖️ 5 + 4 - 2 ✖️ 2 + 6 - 4 = 15
The equations with parentheses added to make them true are;
(4 × (3 + 7 - 6) × 1) + 4 = 20(60 - 18) ÷ (2 + 4) + 10÷2 = 1280 - 36 ÷ (2 + 6 - 2) × (5 + 1) = 443 × (5 + 4) - (2 × (2 + 6) - 4) = 15What is the effect of parentheses in a mathematical expression?Parentheses indicate that operations within it should be completed first before those that are outside the parentheses.
The given terms of the equations can be regrouped with parentheses to make the equations true as follows;
1. 4 × 3 + 7 - 6 × 1 + 4 = 20
The above equation gives;
3 + 7 - 6 = 4
Therefore;
4 × 3 + 7 - 6 × 1 + 4 = 4 × (3 + 7 - 6) × 1 + 4
4 × (3 + 7 - 6) × 1 + 4 = (4 × 4) × 1 + 4
(4 × 4) × 1 + 4 = 16 × 1 + 4 = 16 + 4 = 20
Which gives;
(4 × (3 + 7 - 6) × 1) + 4 = 202. 60 - 18 ÷ 2 + 4 + 10 ÷ 2 = 12
60 - 18 = 42
2 + 4 = 6
The first four terms, therefore gives;
(60 - 18) ÷ (2 + 4) = 7
10÷2 = 5
Which gives;
60 - 18 ÷ 2 + 4 + 10 ÷ 2 = (60 - 18) ÷ (2 + 4) + 10÷2
(60 - 18) ÷ (2 + 4) + (10÷2) = 7 + 5 = 12
Which gives;
60 - 18 ÷ 2 + 4 + 10 ÷ 2 = (60 - 18) ÷ (2 + 4) + 10÷2 = 12
The expression is therefore;
(60 - 18) ÷ (2 + 4) + 10÷2 = 123. 80 - 36 ÷ 2 + 6 - 2 × 5 + 1 = 44
80 - 36 ÷ 2 + 6 - 2 × 5 + 1 = 80 - 36 ÷ (2 + 6 - 2) × (5 + 1)
(2 + 6 - 2) = 6, and (5 + 1) = 6
Therefore;
80 - 36 ÷ 2 + 6 - 2 × 5 + 1 = 80 - ((36 ÷ 6) × 6)
80 - ((36 ÷ 6) × 6) = 80 - ((36 × 6) ÷ 6)
80 - ((36 × 6) ÷ 6) = 80 - (36 × 1) = 44
Therefore;
80 - 36 ÷ (2 + 6 - 2) × (5 + 1) = 444. 3 × 5 + 4 - 2 × 2 + 6 - 4 = 15
3 × 5 + 4 - 2 × 2 + 6 - 4 = 3 × (5 + 4) - (2 × (2 + 6) - 4)
3 × (5 + 4) - (2 × (2 + 6) - 4) = 3 × 9 - (16 - 4)

Using the given linear function, we have that:
a) The equation in standard form is: h - 3.34r - 81.2 = 0.
b) The intercepts are given as follows: h-intercept = 81.2, r-intercept = -24.31.
c) The predicted height is of 164.7 centimeters.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In standard format, the equation is given by:
y - mx - b = 0.
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For this problem, the equation is:
h = 81.2 + 3.34r.
In standard format, the equation is:
h - 3.34r - 81.2 = 0.
From the equation, the h-intercept is of 81.2. To find the r-intercept, we have to solve for r when h = 0, hence:
3.34r + 81.2 = 0.
3.34r = -81.2
r = -81.2/3.34
r = -24.31.
For item c, the radius is given by r = 25, hence the height will be given as follows:
h = 81.2 + 3.34(25) = 164.7.

The answers to all the subparts are given below:
(A) Minimum percentage of commuters in the city: 0.75(B) Minimum percentage of commuters in the city has a commute time within 1.5 standard deviations of the mean: [16.65, 37.95](C) Minimum percentage of commuters who have commute times between 6 minutes and 48.6 minutes: 89%What is the percentage?A percentage is a number or ratio expressed as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent sign, "%," is frequently used to indicate it. A percentage is a number without dimensions and without a standard measurement. By dividing the value by the total value and multiplying the result by 100, one can determine the percentage. The percentage calculation formula is (value/total value)×100%.So, (A) Chebyshev's theorem is used:
There can only be 1/k2 values of a distribution.k deviations from the mean are used.Here k = 2So,
1/k² = 1/2² = 1/4 = 0.25Therefore, the minimum proportion of commuters who are within two standard deviations of the mean is:
1 - 0.25 = 0.75 m(B) Minimum percentage of commuters in the city has a commute time within 1.5 standard deviations of the mean:
Here, k = 1.5
1/k² = 1/1.5² = 1/2.25 = 0.444Consequently, the shortest commute within two standard deviations of the mean is:
1 - 0.444 = 0.56 = 56%Within 1.5 standard deviations, commute times:
[27.3 - (1.5 × 7.1), 27.3 + (1.5 * 7.1)[16.65, 37.95](C) Minimum percentage of commuters who have commute times between 6 minutes and 48.6 minutes:
X - m /sdX = 6= (6 - 27.3) / 7.1 = - 3X = 48.6= (48.6 - 27.3) / 7. 1 = 3So,
1/k² = 1 / 3² = 1/91 - 1/9 = 8/9= 0.888 = 0.89 = 89%Therefore, the answer to all the subparts are given below:
(A) Minimum percentage of commuters in the city: 0.75(B) Minimum percentage of commuters in the city has a commute time within 1.5 standard deviations of the mean: [16.65, 37.95](C) Minimum percentage of commuters who have commute times between 6 minutes and 48.6 minutes: 89%Know more about percentages here:
