How does the perimeter and area change
if each dimension is doubled? Explain!
Answers
Answer:
By doubling the dimension R, we'll actually change the area by a factor of 4 (it will become four times as large). Notice that this same change to the radius would only change the original circle's perimeter (2πR) by a factor of 2.

PLEASE HELP WITH PART B!!
can you also explain y and x, I dont understand part B >
Answers
A. I would suggest including all units in your answer. Both answers are correct but the unit is also important.
average rate of change:
($750 - $350) / (2014 - 2010) = $400 / (4 years) = $100 per year
initial value:
$350
B. Take 2010 to be year 0. Then for year x = 0, the fee is y = $350.
If the fee increases at a rate of $100 per year, this means that when x = 1, y = $350 + $100 = $450. So the graph of the function that models the dog-walking fee is a line that passes through the points (0, 350) and (1, 450), adn the slope of this line is
(450 - 350) / (1 - 0) = 100/1 = 100
which is the same as the average rate of change.
Using the point-slope formula for a line, the equation you want is then
y - 350 = 100 (x - 0)
y - 350 = 100x
y = 100x + 350

2x+65=4x−3
Answers
Answer:
Step-by-step explanation:
Show that if 3x – 7 = 5, then x = 4.
Here, our given statement is 3x – 7 = 5, and we're asked to prove x = 4.
x=4
Statements Reasons
1. 3x – 7 = 5 Given
2. 3x – 7 + 7 = 5 + 7 Addition of 7 to equation (1)
3. 3x + 0 = 5 + 7 Substitution of –7 + 7 = 0 into (2)
4. 3x = 5 + 7 Substitution of 3x + 0 = 3x into (3)
5. 3x = 12 Substitution of 5 + 7 = 12 into (4)
6. 3x⁄3 = 12⁄3 Dividing equation (5) by 3
7. x = 12⁄3 Substitution of 3x⁄3 = x into (6)
8. x = 4 Substitution of 12⁄3 = 4 into (7)
Is there such a thing as being too descriptive? Yep, and that was it, since over half the proof was devoted to telling the reader how to do arithmetic. We'll typically take numerical computation for granted, and write proofs like this:

Answers
Answer:
The first one: the error was that the 3 shouldn’t have been moved but the 5 should have. The correct answer is k=-8
The second one: the error was that they added the 6 and 4, you would only get -10 if the 4 was - the correct answer is -2
You can check your answer by plugging in your answer to the variable and making sure both side equal each other
Step-by-step explanation:
The first one: the 5 should be - from both side so you get k=-8
The second one: the 4 should be + to both sides. And the -6 and +4 should be added together to get n=-2
Remember you always want to get the variables by themselves.

During the fall, you decide to rake leaves and charge $12 for coming to a house and raking, and then $9 for every hour you rake. If you make $57 in each of 3 houses you went to in one day, how many hours did you spend shoveling?
Answers
Answer:
15
Step-by-step explanation:
For 1 house, the charge just to go to a house is $12.
In each house you made $57.
$57 - $12 = $45
The charge per house just for raking was $45.
You charge $9/hour.
$45/($9/hr) = 5 hours
You shoveled 5 hours in each house.
3 * 5 hours = 15 hours
Answer: 15 hours

-1*-2 + -2*-4 = 10 -1*0 + -2*5 = -10
try TS by yourself
the product of two given matrices is [tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex] and [tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex].
Given that,

What is the product of two matrix?The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. If both A and B are square matrices of the same order, then both AB and BA are defined. If AB and BA are both defined, it is not necessary that AB = BA.
Now, [tex]ST=\left[\begin{array}{cc}3&4\\-1&-2\end{array}\right] \times \left[\begin{array}{cc}-2&0\\-4&5\end{array}\right][/tex]
[tex]ST=\left[\begin{array}{cc}(-6-16)&(0+20)\\(2+8)&(0-10)\end{array}\right][/tex]
[tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex]
[tex]TS= \left[\begin{array}{cc}-2&0\\-4&5\end{array}\right]\times \left[\begin{array}{cc}3&4\\-1&-2\end{array}\right][/tex]
[tex]TS=\left[\begin{array}{cc}(-6-0)&(-8-0)\\(-12-5)&(-16-10)\end{array}\right][/tex]
[tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex]
Therefore, the product of two given matrices is [tex]ST=\left[\begin{array}{cc}-22&20\\10&-10\end{array}\right][/tex] and [tex]TS=\left[\begin{array}{cc}-6&-8\\-17&-26\end{array}\right][/tex].
