Answer:
x = 0
Step-by-step explanation:
This is a vertical line, in fact the y- axis
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through
All of the x- coordinates on the y- axis are zero, then
x = 0 ← equation of line
Answer:
There are 800 total books.
Step-by-step explanation:
In order to find this, we need to create a proportion that compares the number of non-fiction books to the total. First would be the scale factor and the second would be the total.
3/10 = 240/x
Now we can cross multiply to solve
240*10 = 3 * x
2400 = 3x
800 = x
Answer:
x=1/3
Step-by-step explanation:
We can solve for x using the second equation, as it only has one variable.
3x+3=4
Subtract 3 from both sides
3x=1
Divide both sides by 3
x=1/3
