Jones has already taken 1 page of notes on his own, and he will take 2 pages during each hour of class. if after 4 hours, he had 9 pages of notes completed, what is the y-intercept of the equation?
a. 2 pages
b. 4 hours
c. 1 page
d. 9 pages

c. 1 page

Step-by-step explanation:

Let x represent the number of hours that Jones takes to finish the pages

Let y represent the number of pages that Jones finishes in x hours.

Jones has already taken 1 page of notes on his own. Therefore, the equation becomes

y = 2x + 1

After 4 hours,

y = 2×4 + 1 = 8 + 1 = 9 pages.

This equation is in the slope intercept form where

m = Slope = 2 pages per hour of class

To get the y intercept, we will substitute x = 0 into the equation. It becomes

y = 2×0 + 1

y = 1

So the y intercept is 1 page

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
