There are 126,720 inches in 2 miles
if f(x)=x-5, find x when f(x)=15
Answer:
x = 20
Step-by-step explanation:
we are given the value of f(x), replace it in the first equation
15 = x - 5
solve for x by adding 5 on both sides
15 + 5 = x
20 = x or x = 20
The value of x is 20.
Algebraic function :Given function is,
[tex]f(x)=x-5[/tex]
We have to find the value of x when [tex]f(x)=15[/tex]
[tex]x-5=15\\\\x=15+5\\\\x=20[/tex]

Standard Form: ax² + bx + c = 0Expand by FOIL-ing (First, Outside, Inside, Last)Step-by-step explanation:
Step 1: Define
(x - 5)²
Step 2: Expand
Rewrite: (x - 5)(x - 5)Expand [FOIL]: x² - 5x - 5x + 25Combine like terms: x² - 10x + 25Answer: x^2 -10x + 25
Step-by-step explanation:
First example the expression.
(x -5)(x-5) Now find the product

The simplified expression is:
[tex]\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)=0.2y+0.2x-8[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{2}{5}y+\frac{1}{5}x-0.2y-6+\left(-2\right)[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a[/tex]
[tex]=\frac{2}{5}y+\frac{1}{5}x-0.2y-6-2[/tex]
[tex]\mathrm{Group\:like\:terms}[/tex]
[tex]=\frac{2}{5}y-0.2y+\frac{1}{5}x-6-2[/tex]
Add similar elements
[tex]=0.2y+\frac{1}{5}x-6-2[/tex]
[tex]=0.2y+\frac{x}{5}-6-2[/tex]
[tex]=0.2y+\frac{x}{5}-8[/tex]
[tex]=0.2y+0.2x-8[/tex]
Thus, the simplified expression is:

6x - 8-10 = 2 (2x+8) + 2x + 2
Answer:
0 = 36 (No Solution)
Step-by-step explanation:
6x - 8 - 10 = 2(2x + 8) + 2x + 2
Add -8 and -10 = -18
6x + -18 = 2(2x + 8) + 2x + 2
Distributing. 2 x 2x & 2 x 8
6x + -18 = 4x + 16 + 2x + 2
Combine light terms.
6x + -18 = 6x + 18
Add 18 to both sides.
6x = 6x + 36
Subtract 6x
0 = 36
Final Answer: 0 = 36 (No Solution)

statistics what is meant by re-expressing or transforming data? what is the purpose of re expressing or transforming data
Re-expressing data means making the facts more appropriate for evaluation by our methods.
We can not use a linear version until the connection among the 2 variables is linear. Often re-expression (transformation) can save the day, straightening bent relationships in order that we are able to suit and use a easy linear version.
• Two easy approaches to re-specific facts are with logarithms and reciprocals.
• Re-expressions may be visible in regular life— all and sundry does it.
We can re-specific gas performance as gallons in step with hundred miles (a reciprocal) and get rid of the bend in the authentic scatterplot.
Therefore, re-expressing data means making the facts more appropriate for evaluation by our methods.

2. Can a triangle have sides with the given lengths? Explain.
1 ft, 3 ft, 7 ft
a. No, because 7+1>3 contradicts the triangle inequality theorem.
b. Yes, because 1+3<7 satisfies the triangle inequality theorem.
c. Yes, because 7+1>3 satisfies the triangle inequality theorem.
d. No, because 1+3<7 contradicts the triangle inequality theorem.
Answer:
option D
Step-by-step explanation:
Sum of measure of any 2 sides of a triangle should be greater than the measure of third side.
The triangle will not have the sides 1 foot, 3 feet, and 7 feet, as these sides do not satisfy the triangle inequality theorem so, option D is correct.
What is inequality?An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. It is most frequently used to compare the sizes of two numbers on the number line.
Given:
The sides of the triangle are, 1 foot, 3 feet, and 7 feet,
We know that the sum of two sides of a triangle is always greater than the third side,
Calculate the sum of sides as shown below,
1 + 3 = 4
Thus, 1 + 3 < 7.
Therefore, these are not the sides of the triangle.

The Buddha taught that just as individual states had laws, there was a universal law. Each person's station in life was a reflection of their karma, or the cumulative extent to which they had followed or broken the universal law in previous lives. Chinese leaders began to appoint skilled bureaucrats rather than solely employing hereditary officeholders, and Confucian thinkers held that people became fully developed members of society through a process of education, rather than simply by noble birth.
