Answer:
18 minutes
Step-by-step explanation:
Because the question may not provide all the information we need to find the amount of time she spent to read 18 pages of the book. Depend on the average reading speed of a person, it is usually from 60s or 1min per page.
Therefore the time she spend reading 18 pages = 1 * 18 = 18 minutes or 1080 seconds
First, simplify the equation given into slope intercept form.
slope intercept form is y = mx + b, where b is the y intercept and m is the slope.
3x - 2y - 5 = 0
I would move the 2y to the other side.
3x - 5 = 2y
Then, since y can't have a coefficient, divide everything by 2;
y = 3/2x - 5/2
So there's your slope intercept form.
Point slope form is:
Where those with a subscript of 1 are part of the same point.
So you already known one point; -8, 8. I'll just do that as the pair with subscript 1. You know the slope as well from the slope intercept form; 3/2.
You can just plug those in.
y - 8 = 3/2 (x + 8)
Now to change this to general form.
First, distribute 3/2 to x and 8.
y - 8 = 3/2x + 12
-3/2x + y = 20
-3/2x + y - 20 = 0
Since there are no fractions, multiply everything by 2.
-3x + 2y - 40 = 0
We first need to find the difference between $70 and $49.
$70 - $49 = 21
Now we find out what percent $21 is of $70.
21/70 × 100 = 30%.
That means the discount is 30%!
Now we must find 30% of $100, which is $30.
Then we subtract $30 from $100.
$100 - $30 = 70$
