Given:
Gil buys 4 books for $16. Then he sells 3 CDs for $27.
To find:
The equations for y, Gil’s change in money after buying a book, and for x, his change in money after selling a CD, in standard form.
Slope of each equation.
Solution:
Gil buys 4 books for $16.
4 books = $16
1 book = $4
Let n be the number of book purchased, then change in money after buying n book is

Here, negative sign represents decrease in money. Here, slope of -4 it means the money decreased by $4 after buying each book.
He sells 3 CDs for $27.
3 CDs =$27
1 CDs =$9
Let c be the number of CDs sold, then change in money after selling m CDs is

Here, slope of 9 it means the money increased by $9 after selling each CD.

Answer:
70.71m
Step-by-step explanation:
In order to find the diagonal, we can use Pythagiras theorem by splitting the field in half and creating a right angled triangle.
A^2+B^2=C^2
50^2+50^2=C^2
5000=C^2
Square root 5000= 70.71m (2dp)
Hope this helped!
Answer:
A significant figure is the first digit in a number that isn't zero. You round to this.
Step-by-step explanation:
E.g. 1959302 to 1 Sig Fig = 2000000
You round to the first figure that isn't zero, which is one
E.g 0.000001373 to 1 Sig Fig = 0.000001 because that 1 is the first digit that isn't zero
