14x-2=6x-14
8x-2=-14
8x=-12
x=-12/8=-3/2
Answer:
t = 6 days
Step-by-step explanation:
We can model both cases with linear equations in the form:
y = ax + b
Sophie was on page 20 and she reads 10 pages per day, so her equation is:
S = 20 + 10t
Jackson was on page 50 and he reads 5 pages per day, so his equation is:
J = 50 + 5*t
The graph of those equations are in the image attached (The blue line is for Sophie and the orange line is for Jackson)
To find after how many days they will be on the same page, we can make S = J and then find the value of t:
20 + 10t = 50 + 5t
5t = 30
t = 6 days
(b+1)/2b
quotient = divided by
we're dividing a number that is 1 more than b (b + 1), with a number twice as large as b (2b).
Answer:
7x^2 -7x +3
Step-by-step explanation:
The synthetic division of the volume by the height is shown below.
(7x^3 -4x +3)/(x +1) = 7x^2 -7x +3
The area of the bottom face is 7x^2 -7x +3.
