Answer:
9
Step-by-step explanation:
if you substitute a for 3 and b for 2 you should get 9
First find slope
slope=m=(9-6)/(-5-3)
m=-3/8
now equation
(y-9)=-(3/8)*(x+5)
8y-72=-3x-15
3x+8y=57
We need to write equation for both mandy and bill on how many books they read depending on how many months passed.
Mandy's equation:
16 + 2x
she starts with 16 read books and she reads 2 books each month which is in total 2*x where x is number of months
Bill's equation:
4x
because from table we can see he is reading 4 new books each month.
now we need to make those 2 equations equal to eachother and solve for x because we want to see after how many months both will read the same that is why we set them equal.
16 + 2x = 4x
16 = 2x
x = 8
That means that in december he will catch her (if i counted months correctly :) )
Answer:
35
Step-by-step explanation:
Yes this is arithmetic; the next two sequences would follow the pattern: 4x+2 and 5x+2
