Can someone solve 2x-3y=9 and give me the slope and y intercept SHOW WORK please

Dominik [7]

Answer:

The slope is 2/3 and the y-intercept is -3

Step-by-step explanation:

First you subtract 2/3 from both sides and get -3y=-2x+9. Then you divide -3 by -2 and -3 by 9 to get y=2/3-3.

Hope this helped I am not good at explaining but I did this unit like two months ago.

There is a total of 36 books on the bookshelf. The number of hardback books is 15 more than twice the number of paperback books.

uranmaximum [27]

The number of hardback books that are on the bookshelf is 29 books.

Let the total number of books be T.

Let the number of hardback books be H.

Let the number of paperback books be P.

Given the following data:

Total number of books = 36 books

To determine the number of hardback books that are on the bookshelf:

Translating the word problem into an algebraic expression, we have;

The total number of books is:

$T = H+P$

The number of hardback books is 15 more than twice the number of paperback books:

$H =2P+15$

Substituting the given parameters into the formula, we have;

$36 = 2P+15+P\\\\36=3P+15\\\\3P=36-15\\\\3P=21\\\\P=\frac{21}{3}$

P = 7 books

For number of hardback books:

$H =2P+15\\\\H=2(7)+15\\\\H=14+15$

H = 29 books
