[tex]f(x) = x + 2[/tex]
[tex]y = x + 2[/tex]
Subtract the sides of the equation minus 2
[tex]y - 2 = x[/tex]
So ;
[tex] {f}^{ - 1}(x) = x - 2 [/tex]

Answer:
a. 8m
b. 7cm
Step-by-step explanation:
a. Area of a square is s², where s is the side length.
To find s:
s² = 64
s = √64
s = ±8
length cannot be negative, hence it is positive 8
b. Perimeter of a square is 4s = P, where P is the perimeter and s is the side length.
4s = 28
s = 7
The cost y (in dollars) of renting a segway for x hours is y=30x+25. Find the initial fee and the cost per hour.
Given:
The cost y (in dollars) of renting a segway for x hours is
[tex]y=30x+25[/tex]
To find:
The initial fee and the cost per hour.
Solution:
We have,
[tex]y=30x+25[/tex] ...(i)
The slope intercept form of a linear equation is
[tex]y=mx+b[/tex] ...(ii)
where, m is slope is b is y-intercept or initial value.
From (i) and (ii), we get
[tex]m=30,b=25[/tex]
The value of m is 30, so the slope is 30. It means cost per hour is $30.
The value of b is 25, so y-intercept is 25. It means the initial fee is $25.

Alan says that two lines in the coordinate plane are perpendicular if and only if the slopes of the lines are m and 1m. Identify and correct two errors in Alan’s statement.
Answer:
First, two lines are perpendicular if one has slope m, and the other has slope -1/m (Not 1m as Alan says)
That is the first error of Alan.
Now, there is another error.
If m = 0, then -1/m tends to minus infinity (in this case we would have a vertical line).
But we can not really divide by zero, so we should state that:
m can not be zero, if a line is horizontal, the perpendicular line must be vertical.

Answer:
c = √58
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
Because we have a right triangle, we can use the Pythagorean Theorem to help us solve for missing side lengths:
7² + 3² = c²
49 + 9 = c²
58 = c²
c = √58
Answer: c = √58

man how df you do dis
Answer:
-2.9375
Step-by-step explanation:
2x-14x+47=0
16x+47=0
16x=-47
x=-2.9375
Answer:
x=7+√ 2 or x=7-√ 2
Step-by-step explanation:
x^2-14x+47=0
Completing the square,
x^2-14x+49-2=0
x^2-14x+49=2
x^2-7x-7x+49=2
x(x-7)-7(x-7)=2
(x-7)^2=2
x-7=√ 2 or x-7=-√ 2
x=7+√ 2 or x=7-√ 2
$6.89 per pound for salmon OR $3.50 for 8 ounces (half a pound) of salmon
Answer: 6.89 per pound (assuming you meant which is the better deal)
Step-by-step explanation:
There are 16 ounces in a pound so you can multiply, 3.5 x 2 (since it is 3.5 for 8 ounces) to get 7. Therefore $6.89 for a pound is cheaper.

Alexander is a stockbroker. He earns 11% commission each week. Last week, he sold $5,400 worth of stocks. How much did he make last week in commission? If he averages that same amount each week, how much did he make in commission in 2011?
Answer: 594 and 30888
Step-by-step explanation:
5400 x 0.11 = 594
594 dollars in commission of one week
52 weeks in a year
52 x 594 = 30888 dollars made in 2011
594 dollars in commission of one week.
$30888 he make in commission in 2011.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Stocks sold= $5400
Commission each week = 11%
So, Commission on Stocks sold
= 5400 x 0.11
= 594
Thus, 594 dollars in commission of one week.
As, 1 Year = 52 weeks
So, He can make in 2011 = 52 x 594 = $30888

If three quarters of a number decreased by twenty is equal to eighty two, what is that number?
A number is :
[tex]x[/tex]
_________________________________
Three quarters of it means :
[tex] \frac{3}{4}x \\ [/tex]
_________________________________
Decrease by 20 means :
[tex] \frac{3}{4}x - 20 \\ [/tex]
_________________________________
Equals to 82 means :
[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]
_________________________________
What is that number ?
x asked so we must solve the above equation for x.
Let's do it....
[tex] \frac{3}{4}x - 20 = 82 \\ [/tex]
Plus sides 20
[tex] \frac{3}{4}x = 82 + 20 \\ [/tex]
[tex] \frac{3}{4}x = 102 \\ [/tex]
Multiply sides by 4
[tex]3x = 102 \times 4[/tex]
Divided sides by 3
[tex]x = \frac{102 \times 4}{3} \\ [/tex]
[tex]x = \frac{102}{3} \times 4 \\ [/tex]
Simplify
[tex]x = 34 \times 4[/tex]
[tex]x = 136[/tex]
So that number is 136 .
