Answer:
y = -2x-7/9
Step-by-step explanation:
Slope-intercept form is y=mx+b where m is the slope and b is the y intercept. Start by solving for y.
-18x-9y=7
-9y=18x+7 (divide through by -9)
y=-2x-7/9
Answer:

We need approximately 1667 floppy disc to store
bytes of data.
Step-by-step explanation:
We are given the following information in the question:
A floppy disc can store 1440000 bytes of data.
We have to convert 1440000 in a standard form.
Standard Form:
- Standard form is a way of writing down very large or very small numbers easily.
- It helps us to express large numbers in powers of 10
The standard form can be written as:

We have positive power of 10 because we have to move to the right of the decimal point.
A hard disc can store
bytes of data.
Number of floppy disks needed to store the
bytes of data =

Thus, we need approximately 1667 floppy disc to store
bytes of data.
Divide total miles by number of days:
151.2 / 24 = 6.3 miles per day
It’s 6 because the full length is 12 and it’s asking for the half of it
