prime factors of 20 = 2 * 2 * 5

9/100 is 9/100 in its simplest form.
You can also say that 9/100=0.09
Answer:
The y-intercept is (0,-12).
Step-by-step explanation:
Given equation is
.
Now question says to find the y-intercept of the given parabola
.
We know that y-intercept means the y-value when x-value equals 0
so let's plug x=0 into given equation
then solve that for y.




Hence the y-intercept is (0,-12).
Please see below solution:
Let x = number of books that Bryan reads2x for amanda = Amanda 3x - 4 for Colin Amanda = 5/8(Bryan + Colin)2x = 5/8(x+3x-4)2x = 5/8(4x-4)
[16x = 5(4x-4)]816x = 20x - 20Subtract 20x from each side-4x =-20-4x/-4= -20/-4 divide -4 to eliminate the -4 in -4xx = 5
Therefore:
Bryan reads 5 books a month.
Since Amanda reads twice as many books a Bryan read so Amanda 10 books a month.
And Colin 11 books a month. 3(5) - 4 = 11
