Since The equation is
[tex]a(n)\text{ = 4n-20}[/tex]To find its inverse we have to proceed to some steps
a= 4n-20
1) Swap a for n, in this case,
n=4a-20
2) Isolate n on the left side by subtracting 4a on both sides:
n -4a =4a-4a -20
n-4a=-20
3) Subtract n on both sides
a-a-4n =-20-a
-4n=-20 -a
4) Multiply it by -1

a bucket contains 15 blue pens 35 black pins and 40 Red Pins. You pick one pin at random find the theoretical probabilities below . Express your answer as a percent to the nearest whole number p(black)=???p(blue or black)=???
The number of blue pen is 15
The number of black pens is 35
The number of red pens is 40
The total number of pens in the bucket = Blue pens + black pens + red pens
The total number of pens = 15 + 35 + 40
= 90
Therefore, the total number of pens in the bucket = 90 pens
The probability that black pen is picked is
Probablity = possible outcomes/ total outcomes
P(black) = 35 / 90 x 100%
P(black) = 0.3888 x 100%
P(black) = 38.88%
P(black) = 39%
P(blue or black)
If its pick at random without replacement then
If the first pick is blue, then the total number of pen in the bucket remains 89
For the first pick will be 15/90
Since the remaining pens is 89, then the second pick is
35/89
Then we have
15/90 + 35/89
LCM is 8010
8010 x 15 / 90 + 35 x 8010 /89 / 8010
89 x 15 + 35 x 90 / 8010
P(blue / black) = 1335 + 3150 / 8010
P(blue or black) = 4485 / 8010
P(blue or black) = 0.559 x 100%
P(blue or black) = 55.9%
P(blue or black) = 56%
Determine whether the triangles are similar. If so, what are the similarity statement and the postulate or theorem used? (image attached)thank you ! :)
ANSWER
ΔOMN ~ ΔOJK; SAS
EXPLANATION
As we can observe in the diagram, the triangles share angle O and we have information about the sides forming that angle, so the postulate to use, in case they are similar, is SAS.
If two triangles are similar, then the ratio between corresponding sides is constant.
Let's assume that the similar triangles are triangle OMN and triangle OJK. Then, the previous statement is,
[tex]\frac{OM}{OJ}=\frac{MN}{JK}=\frac{ON}{OK}[/tex]Replace the side lengths for the first and last ratios - since we don't know the lengths of sides MN and JK,
[tex]\begin{gathered} \frac{30+10}{30}=\frac{3+1}{3} \\ \\ \frac{40}{30}=\frac{4}{3} \\ \\ \frac{4}{3}=\frac{4}{3} \end{gathered}[/tex]The ratio between corresponding sides is constant, 4/3. Hence, triangles OMN and OJK are similar, by SAS.

What is function explain?
A relation between a set of inputs and a set of allowable outputs is called a function, and it has the property that every input is associated to exactly one output. When every element in set A has one end and only one image in set B, then the mapping from set A to set B is a function. Let A & B be any two non-empty sets.Four main categories can be used to classify the many sorts of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element.s(x)= x-3
t(x) = 3x+4
(s•t) = ( x -3 ) ( 3x + 4 )
= ( 3x² + 4x - 3x² - 12 )
= 4x - 12
(s-t) (x) = ( x-3 ) - ( 3x+4 )
= x-3 - 3x + 4
= -2x + 1
(s + t) (-2) = x-3 + 3x+4
= 4x + 1
(s + t) (-2) = 4 * - 2 + 1

The probability of having an even or a number greater than 9 is 2/3.
What is the probability?Probability determines the odds that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0. The more likely the event is to happen, the closer the probability value would be to 1.
The sample space of two 6-sided dice would be 36
Of this 36, there would be 18 which would have an even sum.
There would be 6 with a sum greater than 9.
The probability of having an even or a number greater than 9 = (18/36) + (6/36) = 24 / 36 = 2/3

Answer:
5/9
Step-by-step explanation:
You want the probability that a roll of 2 dice will produce a sum that is even or greater than 9.
EvenHalf the numbers on each die are even. Their sum will be even when the dice show ...
even + even . . . . p = (1/2)(1/2) = 1/4
odd + odd . . . . . . p = (1/2)(1/2) = 1/4
So, the 36 possible outcomes will produce an even sum (1/4) +(1/4) = 1/2 of the time. That is, there are 1/2(36) = 18 outcomes with an even sum.
Greater than 9The sums that are greater than 9 are 10, 11, 12. Of these, 10 and 12 are outcomes that are even, so are already counted.
The sum 11 can be made two ways: 6 +5 or 5 +6.
So, "or greater than 9" adds 2 outcomes to the 18 we have already counted.
Final tallyThe final tally of outcomes of interest is ...
18 + 2 = 20 . . . . of 36 possible outcomes
That is ...
P(even or >9) = 20/36 = 5/9

A car was valued at $41,000 in the year 1994. The value depreciated to $13,000 by the year 2004
Firstly, we have to write the general depreciation fomula as follows;
[tex]V(t)=I(1-r)^t[/tex]where V(t) represents the value of the commodity after a certain t years
I is the initial value of the item
r is the annual percentage change (rate of depreciation)
t is the number of years
a) Here, we want to calculate the annual rate of change
According to the data given in the question;
V(t) = $13,000
I = $41,000
r = ?
t = 2004-1994 = 10 years
Now, we proceed to substitute these values, to find the find of r as follows;
[tex]\begin{gathered} 13,000=41,000(1-r)^{10} \\ (1-r)^{10\text{ }}\text{ = }\frac{13,000}{41,000} \\ (1-r)^{10\text{ }}=\text{ }\frac{13}{41} \\ \\ (1-r)\text{ = }\sqrt[10]{\frac{13}{41}} \\ \\ 1-r\text{ = 0.8915} \\ r\text{ = 1-0.8915} \\ r\text{ = 0.1085} \end{gathered}[/tex]b) To write r in percentage form, we have to multiply the answer in 'a' above by 100
We have this as ;
[tex]0.1085\times100\text{ = 10.85 \%}[/tex]c) Here, we want to get the car value by year 2009
In that instance;
V(t) = ?
I = $41,000
r = 0.1085
t = 2009-1994 = 15
Substituting these values, we have;
[tex]\begin{gathered} V(15)=41,000(1-0.1085)^{15} \\ V(15)\text{ = \$7,321.56} \end{gathered}[/tex]To the nearest 50 dollars, this is $7,300

Molly has 250 trading cards. She gives n trading cards to her friend Carol. Marcus has 430 trading cards. He gives away three times as many cards as Molly does. How many trading cards did Molly give away if Molly and Marcus have the same number of trading cards left?
Molly gave away 90 trading cards out of 250 trading cards to her friend Carol.
Initially molly had 250 cards.
She gave away n trading cards to her friend.
Now molly has (250 - n) trading cards.
Initially Marcus had 4430 trading cards.
The number of cards that Marcus gave away is is three times of molly.
Cards gave away by Marcus = 3n
Now, Marcus is left out with (430 - 3n) trading cards/
After giving away the cards,
Molly and Marcus had same number of trading cards.
So, we can write,
250-n = 430-3n
Now, we have a linear relation between the number of cards given away and the remaining cards,
Further solving,
2n = 180
n = 90.

Ken exercise at a park first he run 3 miles in 30 minutes.Then he rests for 15 minutes.Then he runs 2 miles in 15 minutes.Finally he walks 1 mile in 15 minutes.Assume each running and walking segment was done at a constant rate.skecth a graph to represent ken's exercing at the park.the fisrt segment should begin at (0,0).
The horizontal axis represents the time in hours, and the vertical axis represents the number of miles ran.
So for the first part we have 3 miles in 30 minutes (0.5 hour), so we can draw a line from point (0, 0) to point (0.5, 3)
For the second part, he rests for 15 minutes (0.25 hour), so the y-value doesn't change, therefore we have a horizontal line from (0.5, 3) to (0.75, 3).
Then, we have 2 miles in 15 minutes, so we have a line from (0.75, 3) to (1, 5).
And finally, 1 mile in 15 minutes, so a line from (1, 5) to (1.25, 6).
Sketching the graph, we have:
