Answer:

Step-by-step explanation:
The equation of the given straight line is 2x - 3y + 15 = 0.
Now, we can express the equation as 3y = 2x + 15
⇒
..........(1)
The equation is in slope-intercept form and the slope is =
Therefore, the equation of a straight line which is perpendicular to (1) is
{Where c is any constant}
{Since, the product of slopes of two perpendicular straight lines is -1}
Now, putting c = 1, we get the equation as

Answer:
If the shelves are 4/5 full, then the total number of books in the library is 1,040 books
Step-by-step explanation:
13 roll of bookcases
All the bookcases have four shelves
Total number of shelves = 4 x 13
= 52 shelves
Each shelve holds 25 books each
Total number of books that can be in the shelves altogether = 52 x 25
= 1,300 books
If the shelves are 4/5 full, then the total number of books in the library is,
4/5 x 1300
= 1,040 books
Answer:
11/13 x 4 = 3 5/13
Step-by-step explanation:
Answer:
(4x^2 + 3)(x + 3)
Step-by-step explanation:
Split the equation in the middle so you can factor it out:
4x^3 + 12x^2 | + 3x + 9
Then factor out:
4x^2(x + 3) | 3(x + 3)
Congrats, you completed your equation:
(4x^2 + 3)(x + 3)
