Common difference = 6 - 2.5 = 3.5
(B) recursive formula can be written as
U(n+1) = U(n) + 3.5n
where value of n is 0 to infinity
If two lines have the same slope, they are parallel.
If the product of 2 slopes is -1, the lines are perpendicular.
10. The lines do not have the same slope, so they are not parallel.
3 * (-1) = -3. The product is not -1, so the lines are not perpendicular.
Answer: neither
11. 2/3 and -3/2 are not equal, so the lines are not parallel.
2/3 * (-3/2) = -6/6 = -1
The product of the slopes is -1, so the lines are perpendicular.
Answer: perpendicular
12.
Plot the points (2, 16) and (5, 40).
Draw a line though them.
Then you can use the slope formula to find the slope.
m = (y2 - y1)/(x2 - x1) = (40 - 16)/(5 - 2) = 24/3 = 8
Let's assume the number as x
→ ⅔rd of x =( ⅔)x
Now ⅔ of x is greater than ⅓ of 5 .
So number will be greater than 5/2 .

Answer:
B=30
Step-by-step explanation:
B+35=65
you subtract by 35, and it cancels out on the left side.
what you do to one side you have to do to the other, so you subtract 35 from 65 and you get 30.
......
B=30
