Answer:

Step-by-step explanation:
The correct question is
Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read.
Let y represent the number of pages left to read after x hours.
Complete the equation for the relationship between the number of pages left and number of hours.
Let
x -----> the time in hours
y ----> the number of pages left to read
we know that
The linear equation in point-slope form is equal to

In this problem we have
----> is negative because the linear function is decreasing

substitute




Step-by-step explanation:
2x - 5
x+4 / 2x^2 + 3x - 1
- 2x^2 + 8x
0 -5x - 1
- -5x - 20
0 19
Quotient = 2x - 5 + 19/x+4
Remainder = 19/x+4
Answer:
-1, -12
Step-by-step explanation:
you take b which is 6 and make it negative, then you take a and multiply it by 2, which is 6. you then take the 2 numbers and put the -b over 2a in this formula -b/2a giving you -1 as your x value
after you do that, you input the -1 into the equation as x and the value you get out of that (-12) is the y value of the vertex
Step-by-step explanation:
first one c/a
second one b/a
