Answer:
2(n^2)+5n-3
Step-by-step explanation:
Hi (again)
So using the
2a
3a+b
a+b+c
rules you should get the answer 2(n^2)+5n-3
:) have a great day
Answer:
x
Step-by-step explanation:
5/8 is the length. Just divide 15/56 by 3/7.
Answer:
m = y/x
Step-by-step explanation:
y-y = m(x-x)
simplify:
-2y = m(-2x)
simplify again
-2y = -2mx
divide to get rid of -2 and x
-2y = -2mx
----------------
-2x
y
- = m
x
Answer:
No
Step-by-step explanation:
The constant of proportionality is k = y/x. In this case, k is 5. When you multiply k which is 5 with the x value you should get the y value. You will see that 2 X 5 = 10, 3 X 5 = 15, and 5 X 5 = 25 but 4X 5 is not equal to 24. This means the ordered pair (4, 24) does not lie on the straight line that is formed where all the other ordered pairs (2,10), (3,15), and (5,25) lie.
For a proportional relationship in a table, the k is constant for all the ordered pair x and y values. All the ordered pairs in the table should also lie on the same straight line.
So the answer is no.
