Hello,
H^(-1)(x)=-3/2 x+9
Answer A
Indeed:

y=-2/3x+6-->x=-2/3 y +6 ==>3x=-2y+18==>2y=-3x+18==>y=-3/2 x +9

Plug in method?I am trying to use the plug in method and I did that but then was not sure how to solve the problem after plugging in numbers.

Answers

Well, the picture is cut off below choice-C, and the whole thing is
very confusing to try and read because of trying to do all of your
work in the holes and spaces around the choices. So I'm just
going to ignore all of that, take the question, and work with it.

-- price of one book = k
-- total income if 1 book is sold = 1 · k
-- total income if 2 books are sold = 2 · k
-- total income if 100 books are sold = 100 · k

-- number of books for sale = 2b
-- total income if they're all sold = 2b · k
-- actual number that were sold = (2b - y)
-- actual total income = (2b - y) · k

You don't start with plugging in numbers. This is just testing whether you can find the right equation to plug numbers into.

the equation would be k(2b-y): he has 2b books, they sell for k each--> k*2b, but y books did not sell for k, so it's now k(2b-y)

the answer is A but I hope you understand the process now.

Taylor and Abby shared a $55 cash prize in the ratio 2:3. How much money did Taylor get?

Answers

the 2 to 3 ratio means there was 5 equal shares. because 2 plus 3 is 5

so if you divide 5 into 55 you get 11. each share is 11.

then multiply 11 by or 3 (depending on the person) in this case 2 because we want to know about Taylor

2 times 11 is 22.

Taylor got 22 dollars
